HOW SPEEDFIT WORKS

Grips before it seals

Main ʻOʼ Ring Seal

Stainless steel teeth

grip the pipe

Pipe insert gives

secondary seal

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.

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.

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.

MAKING A GOOD CONNECTION

Pipe Cutter

JG TS

Speedfit

Barrier Pipe

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.

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.

Fittings and pipe should be kept clean bagged and undamaged

before use.

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.

Gap between Cap

and Flange

Pipe mark indicates

full insertion

Twist the screwcap until it

touches the body flange.

This increases the ‘O’ ring

seal around the pipe and

locks the pipe into position.

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.

ADDED BENEFIT TWIST AND LOCK

STANDARD SPEEDFIT FITTINGS

Standard Speedfit connections are made in the same way

as Twist and Lock.

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.

Push pipe up to stop

Secondary Seal

Pipe mark indicates

full insertion.

Pull to check connection

is secure and test the

system. Our recommended

test procedure is shown

in our Technical Checklist

on page 29.

TO DISCONNECT

Ensure that the system

is depressurised.

The screwcap on Twist

and Lock Fittings will

need to be turned back

to the unlocked position.

WHAT NOT TO DO

Fitting may be gripped but not

sealed if pipe is not fully inserted.

Don’t use hacksaws to cut the

pipe or leave burrs on the end of

the pipe.

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.

✗

Don’t use

damaged or

scored pipe.

✗

PREPARE THE PIPE

05 06

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.

Don’t forget to push the

pipe fully into the fitting,

past both the collet (gripper)

and the ‘O’ ring.

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.

Collet covers for use with standard Speedfit fittings, are

available in white or in red or blue to allow colour coding of pipes.

Stops are located at the following distances from the end

of the fitting:

size 10mm 15mm 22mm 28mm

stop distance 20mm 30mm 35mm 44mm

Collet cover

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.

They are not designed to prevent accidental release and

should be fitted when the fitting is in the locked position.

Collet clip

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.

COLLET CLIPS

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

useful to allow water to be

turned back on, overnight for

instance, or if a job has to be

interrupted for another reason.

Stop end

Stop ends are also useful when pressure testing a system

before appliances are connected.

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.

A special 10mm version gives a neat

connection from concealed plumbing

a radiator.

STOP END

STEM ELBOW

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.

The valves, in 10 to 22mm,

have a 1/4 turn open/close

mechanism operated by a

screwdriver slot or a lever.

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.

Speedfit x Speedfit

Mechanism twists out of sight

SERVICE VALVE

Speedfit manufacturer a wide range of connectors

including conventional straight and bent tap connectors.

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.

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.

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.

Other benefits include better flow characteristics and a

more even distribution of hot water.

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.

SPEEDFIT MANIFOLD

The Speedfit range includes an Appliance Tap for

the permanent connection of washing machines and

dishwashers, thus enabling complete water isolation to

the appliance.

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.

APPLIANCE TAP

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.

SUPERSEAL PIPE INSERT

07 08

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.

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 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.

SYSTEM CONNECTIONS

The Speedfit Range includes couplers to connect

Speedfit Pipe to 1/2” to 1” BSP and BSPT. See page 12.

Many but not all compression fittings are suitable for use

with plastic fittings and pipe. Users should therefore

check for compatibility. Compression fittings with short

tube stop depth or brass olives should not be used with

plastic fittings or pipe.

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.

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 fittings can be connected onto chromium plated

copper pipe if the chromium plating is completely

removed to the full depth of the fitting. To ensure

maximum grip, the fitting of a collet clip is recommended.

Connection of Speedfit

pipe to supply pipe of other

materials should be via a

stop tap with a 15mm or

22mm compression outlet.

Speedfit Pipe

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.

Ensure nut and olive are in place before inserting pipe insert.

It is not possible to connect Speedfit fittings to Stainless

Steel Pipe.

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.

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.

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.

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.

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.

Speedfit recommend that mains supply pipework to unvented

water heaters (up to 15ltr capacity), be run in metal pipes.

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.

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.

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.

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.

Similarly a metal bath or radiator not connected to an

extraneous-conductive-part is not required to be connected

to the local supplementry conductors.

The most common way of running pipework to a radiator

is to run both flow and return pipes central to the

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

15mm B-PEX to BS7291 : Part 3 : 1990 Class S 12 BAR 20°C - 4 BAR 82°C - 3 BAR 92°C

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.

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.

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.

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.

ELECTRICAL CONTINUITY

UNVENTED PRESSURISED CYLINDERS

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.

JG Speedfit aluminium foil tape can be used to fulfil the

NHBC requirements for the identification of location of

plastic pipes in or behind a wall surface by a metal

detector. It features a bright aluminium finish, rubber/resin

high-tack adhesive and quality siliconised backing paper

to allow the easy handling of short, cut lengths.

METAL FOIL TAPE

There are two types of pipe clip in the Speedfit range.

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.

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.

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.

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.

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.

Instructions on the drilling of joists is given in the Building

Regulations Approved Document A, and summarised as

follows:

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

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.

Max. dia. of holes = 0.25D

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

Min 3 x hole dia.

The insulation requirements for Speedfit pipe are the same as

those for copper and should comply with BS6700 and BS5422.

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.

For surface mounted pipes

Several types of joists are available and Speedfit recommends

that specific manufacturers details are consulted.

However, the following can be used for general guidance.

•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 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.

PIPEWORK INSULATION

CONCEALED PIPEWORK

TRADITIONAL JOISTS

TIMBER I BEAM JOISTS

Speedfit is well suited for steel frame construction and

care should be taken when installing the pipework.

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.

As with all installations, make sure that any pipework passing

through walls and floors does not affect the fire resistant

properties of the structure.

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.

If incorporating fittings in this way, collet covers or collet

clips must be used with the Standard range of fittings.

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.

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.

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

It is also possible to bend Speedfit Pipe using a standard

pipe bender. The pipe should not be heated with a

blowlamp or hot air gun.

Minimum bend radii for Speedfit pipe are as follows:

Min Radius Pipe Diameter

10mm 15mm 22mm 28mm

with Cold Forming Bends 30mm 75mm 110mm -

with Clips 100mm 175mm 225mm 300mm

For bends of radii smaller than those shown, standard

elbow fittings are recommended.

Gentle bends can be made with pipe clips on either side

of the curve, positioned to maintain the bend radius.

Tighter bends can be achieved

by using the cold forming

bends shown on page 15.

Internal Bending Springs are

available in 10mm to 22mm

sizes, see page 15.

PIPE BENDING

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.

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.

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.

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.

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.

When used in locations vulnerable to rodent attack, all

plastic pipes and fittings should be adequately protected

within sealed ducts.

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

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.

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.

With existing systems, flushing prior to the use of Speedfit

essential to remove any harmful contamination or chemical

residues from elsewhere in the system.

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.

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.

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.

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.

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.

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.

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.

21 22

RADIATOR SYSTEM AND HEAT GRADIENT

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.

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.

Problem: A fitting or part of a fitting dissolved - the fitting

may have blown off the pipe and may have missing

component parts.

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.

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.

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.

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.

COMMON PROBLEMS AND IDENTIFICATION

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.

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.

By contrast, radiators transfer heat from a relatively small

area at a much higher temperature than the space being heated.

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.

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.

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.

FEATURES & BENEFITS

The Speedfit Underfloor Heating System is suitable for

most floor finishes, including ceramic tiles, carpets, vinyl

and laminate.

The thermal resistance of floor covering will have a marked

effect on the performance of the heating system.

Advice on the use of floor coverings and their effect on

the performance of a system is laid out in the Speedfit

Underfloor Heating Manual.

FLOOR FINISHES AND COVERING

SPEEDFIT SYSTEM COMPONENTS

by lagging or painting.

•

Pipe Inserts. Must be used on all installations when using plastic pipe and

should be fully inserted.

•

Electrical Components. Electrical products in the Speedfit Underfloor Heating

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.

•

System Flushing. As is usual practice for any plumbing installation,

flushing of the system prior to the use of JG Speedfit is recommended to

remove any contaminants/chemical residue from elsewhere in the system.

•

Vermin. Speedfit products should not be used in vermin infested areas.

•

Frost Protection. During the installation process it is important that pipe

TECHNICAL CHECKLIST -

UNDERFLOOR HEATING

•

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

nstalled 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.

Threads Size Maximum Torque

Plastic 1/2” 3.0 Nm

3/4” 4.0 Nm

Brass 1/2” 4.0 Nm

3/4” 5.0 Nm

It is recommended that all installations are checked prior to use to determine

that seal has been made.

•

Side Loads.

Fittings should not be subject to excessive side loads and they

should not be used as support brackets. Tubing and fittings should be adequately

supported to prevent excessive side loading.
