Building Regulations
Requirements
All sanitary pipework and drainage
installations must satisfy the relevant
requirements of Part H1 of the
approved documents to the
England, Wales and Northern
Ireland Building Regulations 1990
and the Building Standards
(Scotland) amendment regulations
1982.
Installations in accordance with BS
EN 12056:2
Code of practice for sanitary
pipework will also meet Building
Regulations requirements.
Ventilation
The discharge stack must be
ventilated in order to prevent
pressure building up within the
system and drawing the water seals
in the traps.
Separate ventilation of branch pipes
is required only if the length and
slope of the branch exceeds the
following dimensions:
Maximum length:
(32mm) 1.7 metres
(40mm) 3 metres
(50mm) 4 metres
Slope: 18-90mm per metre
In such cases, the branch pipe
should be ventilated by a branch
ventilating pipe or an anti-syphon
trap should be fitted.
The Automatic Air Admittance Valve
reduces the number of stack
ventilating pipes required to
penetrate the roof in multi-
installations, without affecting
performance of the drainage
system.
Thermal expansion
Within a solvent-weld system it is
important to make adequate
allowance for thermal movement.
This is most easily achieved by
fitting an expansion ring seal joint
between two fixed solvent-weld
joints.
The expansion gap should be
created by pushing the spigot fully
into the ring seal socket, and
marking the position at the socket
face. Then withdraw the spigot by
10mm.
Check subsequently to ensure that
the expansion gap is not lost during
further installation work.
Branch connections
The distance between the centreline
of the lowest branch connection to
the discharge stack and the invert of
the bend at the foot of the stack
should be in accordance with the
following:
A branch pipe should not discharge
into a stack in a way which could
cause crossflow into any other
branch pipe.
Working temperatures
Terrain Soil and Waste systems may
be used to convey liquids with a
maximum temperature of 76°C
when subjected to continuous flow.
Intermittent discharges of up to
100°C may occur provided they are
of less than 2 minutes duration.
Chemical discharges
Terrain Soil and Waste systems are
generally resistant to most
commonly used acids and those
that may be discharged to the
public sewer system. The rubber
seals, however, are less resistant and
it is advised that before any
chemicals are conveyed through the
systems, checks are made to
establish their effects on the
product. Refer to BS CP 312 Part 1
Code of Practice for Plastic Pipework
for further information.
Access
Sufficient and suitable access must
be provided to enable all pipework
to be tested and maintained
effectively. Access covers, plugs or
caps should be installed in positions
to facilitate use of testing
equipment and removal of
blockages.
Fire Spread
In large commercial or housing
developments, compartmentation
may be required by the Building
Regulations 1991 (Part B 3(2)
Schedule 1). In such cases, any
penetrations by sanitary pipework
must be suitably fire stopped.
Suitable measures include the
containment of pipes from floor to
ceiling in a fire resistant enclosure
(with appropriate fire rating).
In addition, the Terrain Firebrake
Intumescent Sleeve has been
designed to meet the highest fire
stopping requirements.
Pipe support
Pipes must be adequately supported
when installed vertically or
horizontally (to falls).
Design Considerations
Design Considerations
≤ 3 storeys 450mm min.
≤ 5 storeys 750mm min.
5 storeys + Ground floor

Fabricated specials
Our Fabrication Service is able to
help you by producing Specials
to overcome those tricky
problems that arise in the design
process and on site.
Standard specials
■These are produced by
making slight modifications
to existing Terrain products
to suit frequently occurring
design problems e.g. special
gutter angles for bay
windows, conservatories etc.
■These products tend to be
required regularly, but in
small quantities.
■Delivery lead time is usually
the same as for standard
catalogue items.
■Standard Specials have an F
prefix added to the standard
number and can be found in
our price list.
Custom specials
■These are designed and
fabricated specifically to
meet the unique design
requirements created by
special architectural features.
They can be made not only
on a one-off or small batch
basis, but also in their
hundreds, subject to the
demands of your particular
project.
■They can be produced to
your precise specification in
virtually any size or shape.
■Custom Specials provide
solutions to otherwise
unsolvable design problems.
■Delivery time depends upon
the complexity of the design
and number required.
■Examples of situations in
which Custom Specials have
provided solutions include a
PVC drain outlet filter
designed to catch tiny pieces
of gold fillings positioned
beneath the operating area
in a dental surgery; and
specially designed silt traps
to deal with drainage needs
at football grounds.
Pre-fabricated stacks
With increased labour shortages,
the more aspects of the
construction process that can be
dealt with in the factory rather
than on-site, the greater the
benefits for everyone.
Solving problems at the design
and manufacturing stage
ensures ‘right first time’ quality,
increased predictability of
construction time and cost, and
improvements to both site
productivity and health and
safety.
Prefab Stacks consist of soil and
waste pipes and fittings pre-
assembled at the factory to pre-
determined lengths to provide a
modular soil and vent stack.
These offer a number of
benefits:
■Time and labour costs on
site are reduced by mini-
mising the joints to be
made.
■Highly efficient for
commercial, leisure and
housing projects where
identical plumbing
arrangements are repeated a
number of times.
■Can be quickly installed,
reducing the need to re-
locate residents, making
them ideal for refurbishment
work.
Taking a typical house as an
example, stacks are pre-welded
and supplied in four sections:
■Drain socket to kitchen
connection.
■Intermediate section
including bathroom
connection.
■Top section through roof.
■Connection to W.C.
They are available in four
colours: grey, white, black and
rustic brown. Delivery time is
dependent on quantities
required.
You provide us with architect
drawings and, ideally the
sanitaryware schedule, and we
do the rest.

TERRAIN FABRICATION
SERVICE
Specialists in
fabrication
The Terrain Fabrication team
works closely with our Technical
Services Department, employing
the latest design and
manufacturing technologies.
Together, they produce high
quality Pre-fabricated Stacks and
Specials, either by making
modifications to existing
products from the Terrain range,
or by conceiving components
from scratch to deal with
particularly awkward problems.
Where fittings are designed
specially, CAD technology is used
to provide accurate drawings,
along with indications of all
relevant dimensions.
Our fabrication team provides
services in two key areas.
Specials
There are occasions on which
even the most comprehensive
standard product system won’t
meet up to the demands of a
particularly complex design or
installation.
And at times like this, the Terrain
Fabrication Service is uniquely
placed to help you.
Pre-fabrication
Shortage of skilled labour is just
one reason for the growth of
pre-fabrication within
construction. Moving significant
elements of the process from site
to factory provides improvements
in quality, cost and time
predictability, productivity and
safety.
With unrivalled expertise in PVC
and HDPE fabrication systems,
our Fabrication Service has been
helping specifiers and
contractors overcome problems,
both at the design stage and on
site, for over 30 years.
Three easy steps for
our Special Fabrication
Service
It couldn’t be simpler to order
Specials or have a Pre-fabricated
Stack manufactured for you.
1. Send a dimensioned sketch
and specification by email,
fax or post to our Technical
Services Department.
2. We will then advise you on
design possibilities and send
you back CAD diagrams, if
necessary, complete with a
part number and price for
your approval.
If the special is being
incorporated into the design
stage of a drainage layout,
be sure to include the
unique part number with
any plans to be passed to
the contractor.
3. You place the order through
your local merchant, stating
the unique product number
and price.
Whether at the design stage or
on site, should you come up
against a problem related to
plumbing and drainage, look no
further than the Terrain Special
Fabrication Service.
