Quality Manufacture

Performance specifications are well within those required
for most normal domestic central heating and water
supply systems including:

Speedfit Fittings have been designed for use with both
Speedfit and copper pipe.

A commitment to quality is at the heart of the John Guest Philosophy.

• Vented and unvented hot water systems

The strictest control is maintained by virtue of the fact that design and manufacture is carried
out in modern purpose built manufacturing centres in west London and at Maidenhead in
Berkshire.

• Mains fed and indirect cold water systems

• Vented central heating systems

Maintaining control over the whole process from initial tool design and tool making through
to final assembly and testing ensuring that only products of the highest quality are produced.

• Sealed central heating systems provided
temperatures and pressures comply with
BS7291 Parts 1, 2 and 3 Class S.

The company believe it is this commitment to quality that has led to it receiving prestigious
awards from many of the world’s leading testing and approvals organisations.

• Underfloor heating

Extensive tests have shown that Speedfit products will
withstand temperatures and pressures well in excess of
normal working conditions.
JG Speedfit should be installed to conform with good
plumbing practice.

Agricultural and Horticultural. Speedfit has many
applications in agricultural and horticultural environments.
Portable Buildings (site cabins, toilets). As with caravans,
Speedfit is well suited to this application.

MAKING A GOOD CONNECTION

STANDARD SPEEDFIT FITTINGS
Push pipe up to stop

PREPARE THE PIPE
Fittings and pipe should be kept clean bagged and undamaged
before use.

HOW SPEEDFIT WORKS
Speedfit Fittings have a unique grip then seal construction made up of a collet with stainless
steel teeth to grip the pipe and an ‘O’ ring to provide a permanent leak proof seal.
Use of the Superseal Pipe Insert ensures a double ‘O’ ring seal.

Pipe Cutter
JG TS

An ‘O’ ring at the head of the insert and the shape of the stem, provide a secondary seal against
the bore of the fitting. A combination of this and the main ‘O’ ring ensure a good connection.
The stem of the insert gives greater rigidity of the length of pipe within the fitting, reducing the
chance of leaks if a side load is applied.

Speedfit
Barrier Pipe

The head of the insert has been designed for ease of insertion.
The additional benefit of Twist and Lock Fittings is that a twist of a screwcap locks the pipe in
position and gives increased compression on the ‘O’ ring for even greater security.

Pipe mark indicates
full insertion.

Secondary Seal

Ensure the pipe is free of score
marks. Cut the pipe square.
When using Speedfit Barrier Pipe
cut along an insertion mark. We
recommend the use of JG Pipe
Cutters.

Standard Speedfit connections are made in the same way
as Twist and Lock.

To prevent damage to the ‘O’ ring
remove all burrs and sharp edges.
When connecting Speedfit Pipe
use a Superseal Pipe Insert. A
twisting motion will aid insertion.
The insert should only be used
with Speedfit Pipe.

Pull to check connection
is secure and test the
system. Our recommended
test procedure is shown
in our Technical Checklist
on page 29.

Push Pipe up to Pipe Stop. If the Speedfit Pipe has been
cut correctly the insertion mark on the pipe will be level
with the collet head.

TO DISCONNECT
NEW TWIST AND LOCK FITTINGS

The fitting should be in the ‘unlocked’ position, this is
shown with a small gap between the screwcap and the
body flange.
Push the pipe fully into the fitting, up to the pipe stop. If
the Speedfit Pipe has been cut correctly the insertion
mark on the pipe will be level with the collet head. The ‘O’
ring on the Superseal Pipe Insert provides a secondary
seal against the bore of the fitting. A good connection
has been made.

secondary seal

Main ʻOʼ Ring Seal

If you are not using collet
clips, ensure that the
screwcaps are in the
locked position.
Pull to check it is secure. It is good practice to test the system
prior to leaving the site or before use. Our recommended
test procedure is shown in our Technical Checklist.

The screwcap on Twist
and Lock Fittings will
need to be turned back
to the unlocked position.
Push the collet square against the face of the fitting by
using fingers or with the help of our collet release tool.
With the collet held in position the pipe can be removed.
The fitting can be used again without the need for
replacement parts.

WHAT NOT TO DO
Don’t use hacksaws to cut the
pipe or leave burrs on the end of
the pipe.

✗
✗

ADDED BENEFIT TWIST AND LOCK
Twist the screwcap until it
touches the body flange.
This increases the ‘O’ ring
seal around the pipe and
locks the pipe into position.

Don’t use
damaged or
scored pipe.

✗
Fitting may be gripped but not
sealed if pipe is not fully inserted.

Don’t forget to push the
pipe fully into the fitting,
past both the collet (gripper)
and the ‘O’ ring.

Do not insert fingers into the fitting as the stainless steel
teeth may cause injury.

Remember to pressure test the completed installation
according to the recommendations in our Technical Checklist.

PIPE STOP DISTANCES

COLLET COVERS
Use a collet cover or collet clip to provide added security
against pipe disconnection, e.g. the fitting coming into
contact with rigid surfaces and behind dry-lining walls.

STOP END

TAP CONNECTORS

SPEEDFIT MANIFOLD

The unique feature of the
Speedfit Concept, the ability
to disconnect the fitting
should you want to, means
the Speedfit Stop End not
only provides a permanent
leakproof seal, but can be
readily removed to allow
work to restart or to allow
an extension to a system.
Thus, the fitting is especially
Stop end
useful to allow water to be
turned back on, overnight for
instance, or if a job has to be
interrupted for another reason.
Stop ends are also useful when pressure testing a system
before appliances are connected.

Speedfit manufacturer a wide range of connectors
including conventional straight and bent tap connectors.

Speedfit have introduced an innovative 22mm x 10mm 4
way manifold. Departing from the usual manifold design,
this new product has 4 in-line 10mm outlets, offering a
neater envelope size and therefore a much smaller
installation space.

STEM ELBOW
Designed to simplify pipe connection
in restricted spaces. The Speedfit
Stem Elbow provides an instant swivel
fitting so pipe can be orientated in
any direction.

Collet covers for use with standard Speedfit fittings, are
available in white or in red or blue to allow colour coding of pipes.
Collet cover

A special 10mm version gives a neat
connection from concealed plumbing to
a radiator.

Other benefits include better flow characteristics and a
more even distribution of hot water.
The range also offers a special and
unique Tap Connector that only
requires a simple hand tightening to
connect up a terminal tap, mixer or
float valve. An integral seal within the
fitting avoids the need for further
sealant. The connectors are useful
when replacing existing brassware or
in other confined spaces.

The 22mm and 10mm Speedfit push-fit connections make
for a fast and easy installation, even in confined spaces.
Whilst designed as a heating product, the manifold can
also be used in a mains pressure hot or cold domestic
plumbing system, to feed bathroom or kitchen taps and
mixers. This allows for a more efficient installation as
every terminal fitting has its own dedicated supply.

Coupling up to a supply is easy. The
pipe is simply pushed home into
the Speedfit connection and is
instantly secured, without the need
for specialist tools.

FLEXI HOSES

APPLIANCE TAP
The Speedfit range includes an Appliance Tap for
the permanent connection of washing machines and
dishwashers, thus enabling complete water isolation to
the appliance.

COLLET CLIPS
Collet clip

SERVICE VALVE
The Speedfit range of brass
chromium plated service
valves can be used on both
hot and cold water services
and central heating. Push fit
connections mean much
reduced installation time,
especially in confined spaces.

Collet clips are available in grey and white for use with
standard fittings to prevent accidental pipe
disconnection.
Red or blue collet clips provide colour coding of pipe on
twist and lock fittings.

The valves, in 10 to 22mm,
have a 1/4 turn open/close
mechanism operated by a
screwdriver slot or a lever.

They are not designed to prevent accidental release and
should be fitted when the fitting is in the locked position.

Manufactured to a quality you would expect from Speedfit,
our range of Flexi Hoses has 40 different patterns.
Available in lengths from 150mm to 1,000mm, ends are
either push fit to union nut or push fit to push fit, including
hoses with an integral service valve operated by a 1/4 turn
screwdriver slot.
Apart from being aesthetically pleasing the new white
hoses offer more flexibility and a larger through bore
for better flow characteristics.

RELEASE AID
The action of pressure in a system could increase the grip
of the collet. The release aid allows a firmer grip on the
collet whilst removing the pipe.

SUPERSEAL PIPE INSERT
The Superseal Pipe Insert has been developed to be used
with Speedfit Barrier Pipe and Speedfit Fittings to provide
an extra line of defence when installing a Speedfit Push
Fit System.
The insert has it’s own ‘O’ ring which, with a stem sliding
within the inside of the pipe, gives a secondary seal
against the inside of the fitting.

Tap connector patterns have
a union nut to connect
direct to a tap or floatvalve.
Lever operated valves are
supplied with both a blue
and a red indice.
The ability of Speedfit products
to twist whilst in situ
allows the screwdriver slot
operating valve to be turned
out of sight, helping to avoid
unauthorised tampering.

A simple push fit connection of the supply pipe and a
plastic thread on the outlet to marry well with the plastic
thread on the hose means the Speedfit Appliance Tap is very
easy to install. The large round handle is easy to grip and turn.

More specialist patterns
have been designed to help
the installation of monobloc
mixers to a 15mm supply.
Sold in pairs, each hose in
the pair has a different
spanner location to ease
connection of the threaded
end into the monobloc’s
inlets.
The hoses are suitable for cold water up to 10 Bar and
hot water (65˚C max) up to 6 Bar and approved by WRAS.

The Speedfit Connection, when made with the insert, has
a number of design features.
Sliding the stem of the insert into the pipe gives greater
compression of the main ‘O’ ring on the pipe and greater
rigidity of the length of pipe within the fitting, reducing the
chance of leaks if a side load is applied.
A connection is easier to make because the head of the
insert has been designed for ease of insertion.
Superseal Inserts are listed on page 14.

check for compatibility. Compression fittings with short
tube stop depth or brass olives should not be used with
plastic fittings or pipe.

PIPE AND PIPE ACCESSORIES

CONNECTION TO RING MAINS

When using compression fittings with Speedfit Pipe, a
Standard Pipe Insert (prefix TSM) must be used to
withstand the compressive pressure of the olive. The olive
must be located within the the length of the pipe insert
and the pipe fully inserted into the fitting. The connection
should not need more than 2 full turns after the olive has
gripped the pipe. JG Speedfit recommend the use of soft
copper olives.

Water-replenishing ring mains are typically used in hotels
and hospitals. They are maintained at a constant high
temperature to supply hot water to distribution pipes to
wards or hotel rooms which may be some way from the
heat source.
These systems are very different from more conventional
domestic hot water and central heating systems.
Speedfit Products cannot be used on ring main systems.
The exception would be those systems designed for
domestic situations which have an intermittent
temperature of less than a maximum of 65ºC. This is in
accordance with BS7291 Parts 1 and 3 Class S.

CONNECTION TO BOILERS
Speedfit pipe should never be connected directly to a boiler.
Although most modern boilers have a high limit
thermostat, residual heat can be conducted by the heat
exchanger. Therefore, Speedfit recommend a minimum of
1 metre from the boiler casing should be run in copper
pipe unless otherwise stated in the boiler manufacturers
installation literature.
A gravity primary circuit operating on an uncontrolled
cooking range or solid fuel boiler should be run entirely in
copper and the heating circuit run in copper for the first metre.
Refer to BS 5955: Part 8 for further clarification.
All appliances should have safety devices to make sure
they cannot operate above the working temperature and
pressure range set out in our Technical Checklist on page
29. If safety devices are not incorporated within the
appliance then external controls will be needed.
Water meters (and other devices) can contain check
valves that prevent the expansion of heated water back
down the main supply from a combi boiler. If plastic pipe
is to be used, a suitable expansion vessel must be fitted.
This is especially important to consider if a water meter is
fitted retrospectively. Speedfit do not recommend the use
of plastic pipe on the main supply between a water meter
and a combi boiler if an expansion vessel is not fitted.
Speedfit Products should not be fitted to a sealed system
oil boiler, back fired boiler or other uncontrolled heat source.
Please also see Drop-Pipe Systems on page 17 and
System Commissioning and Flushing on page 21.

CONNECTION TO MAINS SUPPLY
In modern properties, water enters a building usually in
blue MDPE (medium density polyethylene) pipe. In order
to comply with Water Regulation Schedule 2.10, the
internal plumbing system should be connected via a
Speedfit Stop Valve (Part Nos. 15STV and 22STV) in
conjunction with a PE-Copper Coupler from the Speedfit
range of Underground Fittings.
Speedfit Pipe

Connection of Speedfit
pipe to supply pipe of other
materials should be via a
stop tap with a 15mm or
22mm compression outlet.

As shown in the Product Range List, the Speedfit range of
fittings includes valves, taps, adaptors and connectors for
the plumbing of all typical domestic appliances and fittings.

CONNECTION TO CYLINDER & WATER HEATERS
Speedfit can be used on sealed and open vented heating
systems, where boilers are either heating a hot water
storage cylinder or instantaneous hot water such as a
combination boiler. The temperature and pressure limits
of the system must not exceed the maximum values stated
under the heading ‘Working Temperatures and Pressures’.
When using a traditional copper vented cylinder Speedfit
pipe and fittings can be installed with direct connections
to the cylinder.
16

CONNECTION TO CYLINDER & WATER
HEATERS CONTINUED
Unvented pressurised cylinders can be installed using
Speedfit Pipe and Fittings. However, insertion depths on
compression joints that form part of the cylinder must be
checked prior to installation and the use of standard pipe
inserts (Prefix TSM) is recommended.
In accordance with current U.K. Building Regulations
(Part G), discharge pipes from temperature and/or pressure
relief valves must be run in metal pipework.
Speedfit connections to combined Cylinder/Boiler
units and Thermal Storage Units must be made outside
the casing unless otherwise stated in manufacturers
installation literature.

DROP-PIPE SYSTEMS
Care should be taken when designing and installing a
central heating system where radiators are supplied by
pipe work which drops from an upper floor.
With this kind of system it is possible to trap air in the
upper floor pipe work. When the boiler is fired the increase
in pressure within the pipe caused by expanding air could
cause the pipe to burst.
It is therefore essential that the system be designed so
that any air can be removed from the system either
automatically or manually by installing automatic or
manual air vents at the highest points of the system.

ELECTRICAL CONTINUITY CONT’D

Speedfit pipe should be connected to circulating pumps,
motorised valves in accordance with the section in this
book headed, “Connecting Plastic Pipe To Compression
Fittings”. If Speedfit pipe is not mounted on a supporting
structure, the pipe must be clipped close to the components’
connections to ensure adequate support and to assist in
the reduction of vibration.

IEE Guidance Note 7 provides useful guidance on the
design of electrical installations where there is increased
risk of electric shock. It recognises that the requirement
for supplementry bonding may be relaxed where metal
taps and plastic pipes supply other bathroom fittings.

For heavier equipment, ensure that appropriate metal
brackets provide full and independent support of the
components and that it does not rely solely on the pipework
for support.

Speedfit pipe should not be used to provide the discharge
from unvented cylinders, unvented water heaters and sealed
systems via the temperature relief and pressure relief values.

CONNECTION TO COPPER PIPE
The minimum distance to make a solder connection on
copper pipe inserted into a Speedfit Fitting is 450mm
(18 inches). Ensure that any residual flux solder is not
allowed to come in contact with the fitting. That same
measurement is the safe distance to use a freezer kit to
Speedfit Pipe.

CONNECTING TO COLD WATER STORAGE TANK
To install the Speedfit Tank Connector, unscrew the nut
and push the body of the fitting through the tank hole with
the washer on the inside of the tank.
Hand tighten the nut onto the body. Push the pipe into
the connector.
Note: Hand tightening the nut onto the body is all that is
required. Further mechanical tightening will damage the fitting.

WATER HEATERS
Speedfit recommend that mains supply pipework to unvented
water heaters (up to 15ltr capacity), be run in metal pipes.
Unvented Pressurised Cylinders can be installed using
Speedfit pipe and fittings. However if the safety
parameters of the cylinder exceed those of the pipe and
fittings it is possible to fit a pressure reduction valve on
the out going hot supply pipe. This will not interfere with
any other cylinder safety devices demanded by
regulations as they are all fitted in the incoming side of the
cylinder. Run a short length of copper pipe from the
cylinder connection (about 150mm - 300mm) then fit a
Honeywell DO5F pressure reduction valve. This will
protect the pipe and fittings from excessive pressure in
the event of boiler / cylinder malfunction. The factory
fitted temperature / pressure relief valve on the cylinder
will discharge below 100˚C therefore protecting the pipe
from excessive temperature.

back siphonage, backflow or

RADIATOR CONNECTIONS

The pipes exit a single
gang box (fitted with rubber
grommets) located at the
mid height of the finished
radiator position. This also
provides a fixed point for
other trades to work to and
reduces the risk of damage
to the pipework.
Once the plasterboard is installed the pipes are passed
through the Speedfit Radiator Outlet Plate to exit
plasterboard without the need of unsightly holes.
Metal reducing sets which convert radiator valves from
15mm to 10mm are not suitable for use with Speedfit
Fittings or Pipe as they can cause damage to the plastic.

Washer

The plumbing or heating system installer should have
these aspects checked to ensure compliance with current
IEE regulations. If in doubt please contact the Speedfit
Technical Advisory Service or your local Electricity Authority.

SPEEDFIT BARRIER PIPE
Speedfit Barrier Pipe is manufactured to BS 7291 Parts 1,
2 and 3 Class S and is Kitemarked.
It is made up of 5 layers, the
centre of which is a blue
coloured oxygen barrier
which prevents the ingress
of air into the system, thereby
reducing the effect of corrosion
on metal components.
Because of it’s low thermal conductivity, when carrying
hot water, Speedfit Pipe is cooler and therefore safer to
touch. Relatively low heat loss through radiation means that
a system retains it’s heat longer and delivers hot water
more quickly and with less wastage than a metal system.

PIPE SIZING

TIMBER I BEAM JOISTS

WET PLASTER

For general guidance on pipework sizing, please refer to
BS6700 and BS5449 or the Institute of Plumbing
Engineering Services Design Guide. Speedfit fittings are
suitable for connection to pipe sizes within ± 0.1mm of
nominal size.

Several types of joists are available and Speedfit recommends
that specific manufacturers details are consulted.
However, the following can be used for general guidance.

To prevent surface damage to the plaster caused by
expansion and contraction of Speedfit pipes, it is
important to ensure that all Speedfit pipework is
channelled into the wall and protected with appropriate
sleeving. Alternatively, the pipework can be surface
mounted and boxed in if required for aesthetic appearance.

Firstly, a nail clip is used for fixing to timber
when running concealed pipe work i.e.
underfloor or in a roof space . This clip takes
less time to fit and is compact which allows
pipework to be fixed close together when
space is at a premium.
The second type uses a screw and therefore
takes a little longer to fix. When pipes are
required to cross over, it is possible to add
a spacer to the clip. This will give room
between the pipe and the wall to allow the
pipes to cross over. If pipework needs to be
insulated, using the spacer will give room for
the lagging to be applied.

• If more than one hole is to be cut in the web, the
distance between the edges of the holes must be at
least 2x diameter of the largest hole.
• Generally joists are manufactured with 38mm
perforated knockouts in the web at approximately
300mm centres along the length of the joist.

CROSS WEB JOISTS

The flexibility of Speedfit pipe gives it the ability to be
threaded through concealed or inaccessible spaces
without disruption to surrounding structures, making
major savings in installation time.

Speedfit pipe

Joist

Clips

This will also eliminate the risk of damage by floorboard
nails. There is no need for dry runs since pipe can be cut
and connections made in-situ.
Rigid pipe, such as copper, can only be fed under floor in
short lengths. However, Speedfit pipe, being flexible, can
run from one fitting to another without having to install a
connector in between.
Speedfit needs no jointing materials, eliminating the risk of
fire from the use of a blowlamp, solder and flux.

TIMBER FRAMED CONSTRUCTION
Speedfit is well suited for timber frame construction.
Ensure that the structural integrity is not compromised
when installing the pipework.
If the pipe passes through an external wall, care must be
taken not to damage the vapour barrier and should be
installed on the inside of the thermal insulation layer.
If this is not possible, the use of conduit should be specified
at the design stage.

STEEL FRAMED CONSTRUCTION

All runs should be installed through preformed holes in the
structure and protected by a rubber or plastic grommet.
Where clipping of pipework is restricted, cable ties may
be used to secure the pipe.

Instructions on the drilling of joists is given in the Building
Regulations Approved Document A, and summarised as
follows:

As with all installations, make sure that any pipework passing
through walls and floors does not affect the fire resistant
properties of the structure.

RECOMMENDED CLIP SPACING

1. Holes should be no greater than 0.25 of the depth of the joist.

For surface mounted pipes

2. Holes should be drilled at the neutral axis.

3. Holes should not be less than 3 diameters (centre to centre) apart.
4. Holes should be located between 0.25 and 0.4 times the span
from the support.

DRY LINED WALLS
Speedfit pipework can be easily cabled through studwork
and within wall systems as well as behind “dot and dab”
plasterboard installations. Speedfit 10mm Barrier Pipe is
most commonly used to feed radiators.

Min 3 x hole dia.

Max. dia. of holes = 0.25D

Speedfit Conduit Pipe is supplied
in either 15mm or 22mm in coil
lengths of 25m or 50m. The flexible
convoluted pipe has an outside
diameter of 24mm and 30mm.

On long exposed runs of pipework, the expansion of
Speedfit pipe when warm (1% on length between 20 to
82°C) can cause it to sag between clip fixings. When this
is undesirable, pipework can be boxed in or replaced with
rigid copper pipe. Speedfit pipe and fittings are stabilised
to withstand limited exposure to ultra-violet radiation in
sunlight but are not designed for permanent direct
exposure. Under such conditions painting or lagging is
required. Pipe and fittings should also be lagged to
prevent frost damage.

CHEMICAL EFFECTS
Only water or oil based paints should be used. Do not
allow Speedfit fittings to come into contact with cellulose
based paints, paint thinners or strippers, solder flux or
acid based descalents or aggressive cleaning products. If
there is a risk of any chemical treatments coming into
contact with Speedfit, please contact the Technical Advisory
Service first to check compatibility.

Speedfit is well suited for steel frame construction and
care should be taken when installing the pipework.

TRADITIONAL JOISTS

Clip Spacing

Speedfit pipe and fittings can be laid in concrete and
masonry providing they are installed in conduit pipe with
access boxes for the fittings. As stated in Water
Regulation Schedule 2.7 and BS 8000 : Part 15, fittings
and pipe should be removable for possible replacement.
Insulation is also recommended to protect against heat
loss and the effects of frost.

EXPOSED PIPEWORK

Pipework can be “cabled” through drilled holes in joists
and rafters. Therefore, pipework can be installed after
floorboards have been laid, working below the floor
before the ceiling is installed.
This makes site work far safer as the installer does not
have to balance on open joists with the risk of dropping
tools or equipment on other people below.

LAYING OF PIPE IN CONCRETE AND MASONRY

Unlike I beam joists, pipe can be cabled anywhere within
the open Web as no drilling is required. However, the top
and bottom flanges must not be notched. Avoid
damaging the outside diameter of the pipe as you cable
through the metal cross web members.

Pipe clips should not be fitted any closer than 60mm from
the end of the fitting to allow for expansion. Pipes should
always be adequately supported to prevent undue stress
or side load on the fittings.

Pipe Diameter

Headloss
m/m pipe

• Holes may be located vertically anywhere in the web,
but leave 3mm web at the top and/or bottom of hole.
Do not cut into joist flanges when cutting the web.

If incorporating fittings in this way, collet covers or collet
clips must be used with the Standard range of fittings.

FLUXES AND SPEEDFIT
JG Speedfit does not recommend that fluxes of any type
come into contact with our pipe and fittings. However, if
fluxes are to be used in an environment where Speedfit
is installed then we recommend installers use non-acidic
and zinc chloride free fluxes such as Fernox Flux.

ACOUSTIC
Properly installed, Speedfit pipes are virtually silent in
operation and do not resonate; they absorb the acoustic
vibrations and pressure waves created by cavitations,
water hammer, float operated valve oscillation and other
hydraulic effects. The inherent flexibility of Speedfit pipe
effectively eliminates these troublesome problems, including
those that occur when, due to thermal expansion, metal
pipes rub against structural members and where long,
straight runs of rigid pipe amplify water borne noise.
20

Speedfit products along with other materials such as
electrical cables may be damaged if rodents are present.
If vermin infestation is suspected then a rodent exterminator
should take appropriate action.

BIOLOGICAL
No taste, colour, odour or toxicity is imparted to water by
Speedfit components, nor do they promote
microbiological growth.
In accordance with BS7291: Part 1 Clause 6.7, the opacity
of both pipes and fittings allows insufficient light to pass
for the growth of algae
Tests within the Water Regulations Advisory Scheme,
have approved Speedfit pipe and fittings to BS 6920 for
water quality.

SYSTEM TESTING
On completion of the plumbing and heating system it is
essential that system checking and a hydraulic wet test
takes place. Connections to boilers, radiators and
sanitary ware should first be capped or plugged.
Testing should be carried out at
2 bar for 10 minutes followed by 10
bar for 10 minutes.
This testing combined with other
relevant checks, should reveal most
system problems. Any components
within the system not designed
to take these pressures should
be disconnected.
Before carrying out a pressure test
ensure all Speedfit pipe and fittings
are installed correctly. Speedfit
Barrier Pipe is printed with insertion
marks to help ensure full insertion
has been achieved.
Remember pressure testing is NOT a substitute for
making sure fittings are clean and free of any grit, dirt or
swarf and the pipe is correctly inserted (see Making a
Good Connection, on page 06.

SYSTEM COMMISSIONING AND FLUSHING

For further advice on chemical flushing agents and
inhibitor treatments, the following manufacturers should
be contacted: Fernox Manufacturing Ltd., 01799 550811
or Sentinel Betz Dearborn Ltd., 0151 420 9595.

TECHNICAL ADVISORY SERVICE
The JG Speedfit Technical Advisory Service is available to
assist and advise on all aspects of using the Speedfit
system. The service is available between 8.00am and 4.30pm,
Monday to Friday on Telephone No. 01895 425333 and
Fax No. 01895 425350. Products within this Product Guide
are designed for use within UK plumbing and heating
installations or in other countries where similar installation
requirements apply. For information on products suitable
for use in other countries please consult our Technical
Advisory Service.
We take pride in the quality of our products and all complaints
are investigated thoroughly. If you have a problem with a
Speedfit Product please return both fitting and pipe to us
for investigation. We will need at least 50mm of pipe to
ensure an accurate analysis. If there is a suspicion that the
pipe is faulty, please provide marking details from the pipe.

COMMON PROBLEMS AND IDENTIFICATION
Problem: Burst or melted pipe.
Pipe will be distorted showing either a ‘Parrot beak’ look
or a long opening with the edges of the pipe melted in a
wave shape.
Identification: A ‘Parrot beak’ will have been formed by
the pipe bursting due to the water freezing. If the Pipe has
a melted appearance it will have been subject to a
temperature in excess of 128 degrees Celsius. This will
have been caused by direct contact with a heat source
such as a blowtorch or flue pipe or by water or steam
within the system rising above safety levels.

UNDERFLOOR HEATING
The Speedfit Underfloor Heating System has been designed
to be as quick and easy as possible to install with component
parts manufactured to UK and European standards.

In concrete floors, the pipe is laid on insulation and then
covered with a screed on which can be laid almost any type
of floor covering.
For timber floors, spreader plates are laid between the joists
and the floor decking or on the underside of the floor.
Speedfit Pipe is pushed into the grooves on the plates.
The floor area is typically warmed to between 25ºC and
28ºC, providing an even distribution of heat at only slightly
higher than room temperature. The system is controlled
by one or more thermostats which signal the Pump Pack
when heat is required.

UNDERFLOOR HEATING SYSTEM
An Underfloor Heating System heats mainly by radiation.
Radiant energy is emitted by the floor giving an even
distribution of heat. No cold spots, hot ceilings or cold feet.
The overall effectiveness of an UFH heating system can
be seen below.
The heat is concentrated where it is most needed for
comfort and efficiency.

Ceiling
18°C

Identification: The fitting will have failed because of a
chemical attack. The most common attack is from acid
based solder flux running down into the fitting during
soldering of a nearby copper fitting or flux coming into
contact with the fitting in some other way.

For the installation of central heating systems flushing
procedures must be in line with BS7593 code of practice
for treatment of water in domestic hot water heating systems.

Problem: The fitting has blown off the pipe. Fitting is
missing the collet, the pipe insert is still inside the fitting
after the pipe has come out.

Flux residues used in the soldering of capillary fittings are
very corrosive. Dirt and grit, which can enter the system
when Speedfit pipe is being pushed through underfloor or
across a roof space, must be removed.

Identification: If this happens on first fix, the most likely
reason is that the pipe has not been fully inserted into the
fitting, up to the pipe stop, and the system has not been
pressure tested.
If the collet (gripping device) is missing everything will
blow out. If the collet is there and the pipe support is still
inside the connector but the pipe has still blown out, this
means that full insertion had not been accomplished.

FEATURES & BENEFITS
The Speedfit Underfloor Heating System offers many benefits
to the consumer. These include:
Installation
It is simple to install, requiring the minimum of installation
effort and little maintenance.
Comfort
The system uses radiant heat, the most comfortable form
of heating, to give a good even distribution of warmth
over the whole room.
Space
The system in unobtrusive and space saving which means
every square metre of floor and wall space can be fully
utilised giving freedom of interior design.
Noise
Compared to radiator systems the system is virtually silent running.
Health
Dust is minimised reducing the problem of house dust
mites. Reduced numbers of hot surfaces and sharp edges
minimise risk of burns or injury.
Economic
Underfloor Heating Systems are designed to operate at
lower temperatures than radiator systems, resulting in
reduced energy consumption and lower heatloss from the
building structure.
Control
The system is easy to control and the small temperature
difference between the floor and air means the system is
virtually self - regulating.

Problem: Weep from fitting.
Identification : The pipe has not been fully inserted up to
the pipe stop or one or both of the ‘O’ rings have been
damaged by burrs or sharp edges on the end of pipe. See
‘What Not to Do’ on page 06.

Ceiling
24°C

The Speedfit System has water being pumped from a
boiler to a pump pack, where it is mixed to approximately
50ºC then distributed via a manifold to heating circuits
made using Speedfit Barrier Pipe. The pipe is laid in
concrete or suspended just below the surface of the floor.

Problem: A fitting or part of a fitting dissolved - the fitting
may have blown off the pipe and may have missing
component parts.

With existing systems, flushing prior to the use of Speedfit is
essential to remove any harmful contamination or chemical
residues from elsewhere in the system.

The radiator system heats mainly by convection. This
results in the floor being the coolest place in the room,
with the mass of warm air at ceiling level.

Underfloor heating provides the most comfortable even warmth
of any heating system. It is economical to run and virtually
maintenance free. The principle has been with us since
Roman times but is still the system of choice in some
European countries, accounting for 70% of installations.

Floor
24°C

Environment
Underfloor heating is suitable for use with the most energy
efficient and environmentally friendly heating systems
including condensing boilers, solar power and heat pumps.

FLOOR FINISHES AND COVERING
The Speedfit Underfloor Heating System is suitable for
most floor finishes, including ceramic tiles, carpets, vinyl
and laminate.
1.70

When used in locations vulnerable to rodent attack, all
plastic pipes and fittings should be adequately protected
within sealed ducts.

RADIATOR SYSTEM AND HEAT GRADIENT
By contrast, radiators transfer heat from a relatively small
area at a much higher temperature than the space being heated.

2.70

PROTECTION AGAINST RODENTS

During the commissioning of a heating system, all air
must be removed from the system before the boiler is
allowed to fire. This will ensure pockets of air do not
cause localized overheating within the system as this
could have a detrimental affect on the pipework and
boiler.

The thermal resistance of floor covering will have a marked
effect on the performance of the heating system.

INSTALLATION IS QUICK AND EASY
SOLID FLOOR INSTALLATIONS

Connect the ends of the
pipes to the Manifold.

The screed is an important and integral part of the UFH
system, transferring energy from the pipes to the area to
be heated. The response of this ‘thermal mass’ will depend
on its depth and make up.
The usual depth of screed is 65 - 75mm thick but it is possible
depths can be reduced to assist in improving performance.

PIPE LAYOUT IN SOLID FLOOR INSTALLATIONS

The system is filled and
pressure tested.

The shape of the room and the position of the outside
walls and windows will determine the pattern of the pipe
layout. The counterflow pattern is recommended although
other options are shown below.

• Expansion (PEX pipe). 1% on length between 20°C and 82°C.
• Flow rates. Comparable with metal systems.

• Cleaners, inhibitors and descalents. For advice on the replenishment of
additives such as corrosion inhibitors, the following manufacturers should
be contacted: Fernox Manufacturing Limited on 01799 550811 or Sentinel,
BetzDearborn Limited on 0151 420 9595.

• Paint and Chemicals. Use only water or oil based paint. Collet covers
prevent paint ingress into fittings. DO NOT ALLOW CONTACT WITH
oil based jointing compounds, cellulose based paints, paint thinners, paint
strippers, solder flux, acid based descalents or aggressive cleaning products.

• Solder Flux. No fluxes of any types should come into contact with
JG Speedfit Pipe and Fittings. If fluxes are to be used in an environment
where Speedfit is installed, then (1) extreme care should be taken to ensure
that no such contact takes place and (2) JG recommend installers only use
fluxes tested and approved in writing in advance by JG. At the date of this
publication, the only such approved flux is Fernox Flux.

• Chlorine. Speedfit is not suitable for use in systems where the water
contains high levels of chlorine. e.g. swimming pools, fountains etc.

• Exposure to sunlight. Speedfit products, when used indoors, are not
affected by sunlight. When used outdoors protect from ultra violet light
by lagging or painting.

• Pipe clips. Pipe clips should not be fitted any closer than 60mm from the
end of the fitting. Pipe should be adequately supported by pipe clips to
prevent undue stress (side load) on fittings.

• Pipe inserts. Must be used on all installations when using plastic pipe
and should be fully inserted. Only use a Speedfit Insert with Speedfit Pipe.

• Metal Joists. When ʻcablingʼ plastic pipe through metal joists ensure rubber
grommets are in place to prevent damage to pipe. Use of collet covers or
collet clips on fittings recommended.

• Connection to boilers. A minimum 1000mm run of copper pipe must be
installed between the boiler and the Speedfit system, as per BS5955: Part 8.
• Connection to copper pipe. 450mm is the minimum distance to make
a solder connection on copper pipe inserted into a Speedfit Fitting. Ensure
that any residual flux solder does not come into contact with the fitting.

• Concrete and masonry. Speedfit pipe and fittings can be laid in concrete
and masonry providing they are installed in conduit pipe with access boxes
for the fittings. This is to enable the pipe to expand and provide accessibility
for both pipe and fittings. As stated in Water Regulation Scheme 2.7 and BS
8000 : Part 15, fittings and pipe should be removable for possible replacement.
Insulation is also recommended to protect against heat loss and the effects
of frost.

• Electrical continuity. If Speedfit is used in an existing metal system which
may have been used for earthing, electrical continuity should be reinstated.
• Valves and taps. Plastic 15mm and 22mm valves and taps available from
JG Speedfit Ltd are not suitable for central heating installations.
• Collet Covers. Collet covers provide added security against pipe
disconnection, e.g. the fittings coming into contact with rigid surfaces
and behind dry-lining walls. They are offered in white as standard and
in red or blue to provide colour coding of pipe.

• Collet Clips. Grey collet clips are used with standard fittings to prevent
accidental pipe disconnection. Red or blue clips provide colour coding
of pipe. Red and blue clips should not be used to prevent accidental
release of pipe.

• System testing. To ensure the pipework and fittings have been installed
correctly, whether it be on a new or extended system, it is essential that the
system is checked and hydraulically wet tested. Testing should be at 2 bar
for 10 minutes and 10 bar for 10 minutes. This testing, combined with other
relevant checks, should reveal installation problems and is regarded as good
plumbing practice. However, system testing should not be regarded as a
substitute for correct installation (see also “Making a Good Connection”).
• System flushing. As is usual practice for any plumbing installation, flushing
of the system prior to the use of Speedfit is recommended to remove any
contaminants/chemical residue from elsewhere in the system.

• British Gas Service has accepted the John Guest Speedfit fittings as being
suitable for open vented and sealed central heating systems and as eligible
for acceptance onto its service contracts.

• Vermin. Speedfit products will need special protection in vermin infested areas.

• Maximum Torque figures (BSP & BSPT). Plastic threads are not generally as
strong as brass threads. Customers and end users should be aware of this
when choosing products for their applications. Overtightening of plastic threads
will cause undue stress and eventual cracking and leakage. The maximum
torque figures for BSP and BSPT threads used on Speedfit plumbing products
in mating threads conforming to the relevant BS or International thread
standards are shown below.

Systems are designed only to be used in U.K. Electrical Supply situations.

• Electrical Continuity. If Speedfit is used in an existing metal system which
may have been used for earthing, electrical continuity should be reinstated.

• Collet Clips. White and Grey collet clips are used with standard fittings to
prevent accidental pipe disconnection. Red or blue clips provide colour
coding of pipe. Red and blue clips should not be used to prevent accidental
release of pipe.
• Pre-Screed System Testing. To ensure the pipework has been installed
correctly and prior to the screed being laid, it is essential that the system
is checked and hydraulically wet tested.
Testing should be carried out at 2 bar for 10 minutes and 10 bar for
10 minutes.

This testing, combined with other relevant checks, should reveal installation
problems and is regarded as good plumbing practice.
• Pressurisation During Screed Laying & Curing. In accordance with
BS1264-4, the system should be left under pressure at a minimum of 6 bar for
the duration of the laying and curing of the screed.
Under NO circumstances should the UFH System be used to quicken
the screed drying process.

• Chemical Effects. For below ground applications the fittings require
no additional preparations - coating etc. When used above ground,
avoid contact with aggressive chemical compounds. Protect from frost
where necessary. In the United Kingdom, potable water does not
contain high levels of chemicals (eg chlorine etc) that would adversely
affect Speedfit Underground Fittings.
• Exposure to sunlight. Permanent exposure to direct sunlight will
necessitate lagging the fittings.
• Pipe Inserts. Pipe inserts must be used and fully inserted on all
connections to MDPE or LDPE pipe.

• System Testing. Pressure test to 1.5 times working pressure for 10
minutes before connecting to the mains supply. It is recommended
