Introducing new Recycore Soil Pipe
Recycore® Technology is Wavin’s new and innovative technology to reduce the use of virgin materials in its products.
It has been developed to help the construction industry achieve a lower carbon footprint and improve its sustainability credentials.
Recycore® Technology uses as much recycled material as possible whilst ensuring that products have at least the same proven performance characteristics as the virgin products that they replace.
Recycore® Technology products are tested to industry standards and, where applicable, will be third-party approved, e.g. Kitemarked.
Therefore, Recycore® Technology acts as a quality assurance mark for both high quality and sustainable products.
Wavin has applied Recycore® Technology to its new multi-layer, solid-core pipes, made with over 50% recycled content.
Same PerformanceSame QualityBetter Environment
Why Recycore® Technology?
There is growing demand from the construction industry for greener products that can be more easily recycled or that are made from recycled materials; or, better still, a combination of the two.
WRAP, DEFRA and the Environment Agency are all on record saying that they would like to see greater levels of plastics recycling in the UK.
It is not just government and legislative demand that is pushing change either. Wavin’s research has revealed widespread market demand for construction products that are more environmentally friendly. Recycore® Technology is Wavin’s way of helping customers to meet tough new regulations and their own sustainability commitments.

Design l Applications l Pipe Sizing
Applications
General principles
OSMA Soil & Waste systems are designed to
convey soil drainage and waste safely away
from appliances to a soil stack or drain (see
Fig. 3). The systems are suitable for above
ground sanitary fittings and appliances in
domestic, commercial and public buildings.
However, special requirements may apply to
some trade wastes including:
l High temperature and chemical effluent
l Discharges from hospitals and laboratories
For maximum operating temperatures, see
Materials: Properties and Performance,
page 34.
Pipe Sizing
Soil systems
Stack
The internal diameter of a discharge stack
should not be less than that of the largest
trap or appliance discharging into it.
EXAMPLE: If a WC trap diameter is 110mm,
the discharge stack must be minimum
diameter 110mm.
Vent
Dry sections of vent pipe should typically
have the same internal diameter as the
discharge stack. However, for 1- or 2-storey
houses, the dry section may be 75mm
diameter without affecting performance.

Table 19: Minimum Tubular Trap SizesWaste systems
The internal diameter of the waste pipe
should not be less than that of the largest
trap or appliance discharging into it.
Minimum tubular trap sizes are given in
Table 19 opposite.
Combined waste systems
Waste pipe diameters should be increased at
the point where waste from two appliances
meet (see Fig. 4).

Maximum Pipe Runs
Waste systems
The maximum recommended pipe run from
trap to stack, serving single or combined
appliances, is as follows:
– 3m for 40mm pipe
– 4m for 50mm pipe
If the pipe run exceeds the recommended
maximum lengths above, an increased risk
of blockage and/or siphonage may occur:
Design l Pipe Runs l Thermal Movement
l The pipe run must be vented to prevent
self-siphonage or induced siphonage.
See page 98 for details of use of
OSMA Air Admittance Valve 4S303
l Access to be provided wherever possible
l Provision for thermal movement is required
in the case of Solvent Weld systems (see
below)
Thermal Movement
Push-Fit systems
Correctly made and anchored ring-seal/
push-fit joints will accommodate thermal
movement with no requirement for
expansion fittings.
Solvent Weld systems
(see Fig. 5)
Provision for thermal movement is required:
l For all pipe runs over
– 3m for 32, 40 or 50mm pipe
– 4m for 82, 110 or 160mm pipe
l Between any two fixed points 1m or more
apart
Fixed points include:
l Fittings supported by socket brackets
l Changes of direction
l Branches from other appliances
Pipe brackets allow the movement of
pipework between fixed points whilst
keeping the pipework steady.
The following components are available for
the creation of thermal expansion joints:
COMPONENTS
PVC-U Solvent Weld Soil system:
Expansion Cap 4S416 (110mm) and 6S416
(160mm)
ABS Solvent Weld Waste system:
Expansion Socket 4Z/5Z/2Z124
PVC-C Solvent Weld Waste system:
Expansion Socket 4M/5M/2M124
Expansion above highest fixed point taken up through roof.
Fixed point due to socket bracket.
Expansion between fixed point and drain connection taken up within drain socket.
If a solvent welded fitting is provided on the ground floor it should be fitted with an expansion socket.

Pipe Support
Support Centres
Pipe should be supported in accordance
with Table 20 below showing maximum
support centres for pipes installed vertically
and horizontally.
Brackets are available to meet all support
requirements for OSMA Soil & Waste
systems.
Suspended pipework
Bracket assemblies are available for
suspended sanitary and drainage
installations within a building.
The Suspended Bracketing system (see
Fig. 6) offers socket or pipe bracketing in
110mm and 160mm sizes and is adjustable
to accommodate pipe falls. For installation
details see page 106.

Access
Access points should be provided to enable
all pipework to be tested and maintained
effectively. To facilitate use of testing and
cleaning equipment, access points should
be positioned so that:
l Building structures such as walls and
ducts do not impede use of the equipment
l No danger or nuisance is likely if leakage
should occur
This can be achieved by positioning
access points above the spill-over levels
of any pipework which may be affected by
blockages.
Access fittings
A wide range of access fittings are
available, including access pipes, bends
and branches. See the Product Selector
section for full details.
Access may also be created at an
appropriate position in 110mm pipe by
installing Access Saddle 4S275 (see Fig.
7). This fitting can also be installed post
construction. For installation details see page
108.
Access to ranges of WCs
Branch pipes serving ranges of WCs should
incorporate access points:
l At the head of the run
l Wherever the pipe changes direction
Venting of these branch pipes is not normally
necessary, except:
l Where more than 8 WCs are being served
l Where there are several changes of
direction
Urinals
Waste pipe serving urinals can be subject to
build up of deposits, especially in areas of
hard water:
l Make provision for access to all areas of
the waste system
l Keep pipe runs as short as possible: less
than 3m is recommended
To increase self-cleansing, it is advisable for
wash basins with resealing bottle traps to
discharge into the waste system.
See BS EN 12056:2000 for provision of
access.

Design l Offsets
Offsets
Offsets are permitted in the dry portion of the
stack and do not require venting.
Offsets in the wet portion of a stack
should ideally be avoided. Where this is
unavoidable, use large radius bends.
A secondary ventilation stack may be
necessary to connect above and below the
offset, to reduce siphonage threat to traps.
The diameter of this ventilation stack
pipework is typically half that of the
discharge stack. (see Fig. 8)

WC Manifolds
Connecting multiple WCs
OSMA Manifold Branches can be used to
connect multiple WC outlets to a common
soil discharge float leading to the soil
and vent pipe (SVP). Up to 8 WCs (to BS
5503) can be connected, depending upon
gradient.
The Manifold Branches are designed to
be placed between the WC outlet and the
wall behind it. As WC designs vary, this
space should be checked to ensure there is
sufficient room for manifold installation.
Eleven Manifold Branches include:
COMPONENTS
l 4S602 to 4S606: Five left-hand angled
versions
l 4S612 to 4S616: Five right-hand angled
versions
l 4S601: One straight Branch
The angled Branches are graduated from 8°
to 38° in 7½° increments.
Each Branch, including the straight Branch,
incorporates a WC Connector, with integral
gasket, providing a minimum 2½° deflection
all round.
The gradient will be between 0.5° and 5° (9
to 90mm per metre). The maximum available
fall from the first WC (furthest from the SVP)
to the last WC (nearest to the SVP) is 88mm
(see Fig. 29).
Fig. 29 Left hand float for 8 WCs
Planning component needs
Use the following procedure, in conjunction
with the Graduated Scales Diagram (see Fig.
31), to determine which Manifold Branches
are required:
PROCEDURE
1. Draw 1:50 scale plan of proposed WC
positions
2. Establish Left- or Right-hand orientation.
Facing the WCs:
– If the SVP will be at the Left end, use
Section A of the Scales
– If the SVP will be at the Right end, use
Section B of the Scales
3. Select the Scale for the required gradient
of the float run
4. Align arrowhead with first WC (furthest
from SVP)
5. Provided all WCs fall within the Scale,
proceed to Step 6. If not, select a
shallower gradient and return to Step 4
6. Note each part number where the centre
line of the WC outlet concerned falls
within a section
NOTE: If the centre line of the WC outlet
falls between two sections, either Manifold
Branch is suitable. In some cases, with
shallow gradients and close-set WCs, the
same Manifold Branch will be appropriate
(see example illustrated).

Ventilation
General principles
Discharge pipework must be vented
to prevent self-siphonage or induced
siphonage, and to protect traps.
Use of a separate ventilation stack to
atmosphere is generally not required unless
a sharp offset in the stack cannot be avoided
(see also page 88).
Branch pipes
Separate ventilation of branch pipes is
required only if the length and slope of the
branch exceeds the dimensions set out in
BS EN 12056:2000 or Part H of the Building
Regulations (England & Wales), Part M
(Scotland).
Fig. 32 Valve operation
Air Admittance Valves
In many cases, and subject to certain design
considerations, OSMA Air Admittance
Valves (AAVs) may be installed as an
alternative to traditional venting techniques.
These reduce the number of ventilating
pipes required to penetrate the roof in
multi-installations, without affecting the
performance of the drainage system.
AAV description and operation
OSMA AAVs include a diaphragm which,
in the closed position, seals the unit and
prevents foul air from escaping. Whenever
internal pressure drops, the higher pressure
external air opens the diaphragm to admit
air and equalise the internal/external air
pressure (see Fig. 32).
Design l Ventilation
Soil stack ventilation
OSMA A1 Rated 110mm Air Admittance
Valve 4S304 is designed for venting of:
l 110mm soil stacks up to 10 storeys
l 110mm stub stacks
The 110mm AAV may be used on runs
serving a row of 10 dwellings, provided
the vent stack closest to the main sewer is
vented traditionally to atmosphere.
See also Drain Ventilation overleaf.
When used to vent a soil stack, 110mm
Air Admittance Valve 4S304 should be
located:
l Within a building, fitted vertically
l Preferably in a non-habited space (duct or roof-space)
l Where there is no risk of freezing
l Where it is accessible but not at risk of interference by vandals
l Fitted 200mm above the highest branch
For full installation details see page 112.
NOTE: This should not be the only vent to a
drainage system discharging to a septic tank
or intercepting trap.
OSMA A2 rated 110mm Air Admittance
Valve
4S306 is designed for venting of:
l 110mm soil stacks up to 3 storeys
l 110mm stub stacks
The 110mm AAV may be used on runs
serving a row of 10 dwellings, provided
the vent stack closest to the main sewer is
vented traditionally to atmosphere.
See also Drain Ventilation overleaf.
When used to vent a soil stack, 110mm Air
Admittance Valve 4S306 should be located:
l Within a building, fitted vertically
l Preferably in a non-habited space (duct or roof-space)
l 150mm above the insulation in attic installations
l Where there is no risk of freezing
l Where it is accessible but not at risk of interference by vandals
l Installed above spillover level of highest
appliance
NOTE: This should not be the only vent to a
drainage system discharging to a septic tank
nor intercepting trap.
All plastic construction cannot rust or corrode
Also polystyrene cap prevents freezing
Push-fit rubber connector into open top of 110mm stack no solvent welding needed
Insect screen prevents ingress of insects or vermin
Automatic valve action OPENS to admit fresh air when negative pressure occurs -

Ventilation continued
Ventilating roof screeds
Moisture in roof screeds may be caused by:
l Rainwater during drying/curing period
l Condensation from within the building,
resulting in moisture vapour pressure
build-up beneath the waterproofing
This could lead to:
l Distortion, blistering and deterioration of
mastic asphalt and mineral felt-covered
roofs
l Reduced thermal insulation
l Staining of ceilings immediately below roof
level (see Fig. 32)
The OSMA Breather Vent 4S700 installed
at 6 metre centres will allow this potentially
damaging moisture-laden vapour to escape.
For full Breather Vent installation details, see
page 117.Fig. 35 OSMA Breather Vent
Extract systems
Certain buildings require regulated airflows
for use with ventilation and extraction
systems (e.g. blocks of flats, hotels, student
accommodation).
The OSMA Extract Valve 4S709
(see Fig. 36) is solvent welded direct onto
110mm pipe to provide airflow that can be:
l Adjusted to the required rate
l Locked against unauthorised interference
The Extract Valve has a polypropylene
msnap cover over a PVC-U body. It contains
no metallic components and so is
non-corrosive in steamy and damp
atmospheres. For full installation details, see
page 118.
Design l Ventilation
Ventilation in radon gas areas
Certain areas of the UK (including Cornwall,
parts of Somerset, Northamptonshire and
Derbyshire) are known to be susceptible to
radon gas contamination.
Protective measures are explicitly required
by Building Regulations Approved Document
C2 when new building is proposed in
areas where this possibility exists. Specific
guidance is available:
l In Report Number BR211 – Radon:
guidance on protective measures for
new dwellings published by the Building
Research Establishment, or
l By telephoning the BRE Radon Hotline
on 01923 664707
All OSMA Soil & Waste pipework is suitable
for use in radon ventilation systems, but
solvent weld joints are advisable.

Design l Fire Stopping
Fire Stopping
Fire Stop Seals
OSMA Fire Stop Seals prevent the spread
of fire, smoke and hot gases through plastic
pipes that penetrate fire compartment floors
and walls.
The Seals consist of two half shells of metal
which are clipped around the pipe and
anchored to the structure. The metal shell
contains an intumescent material which
reacts under intense heat.
Fire Stop Seals can be installed horizontally
or vertically and provide an economic
alternative to constructing fire resistant
ducts.
Seals are available for four pipe sizes:
FITTINGS
l 2S001 for 50mm waste pipe
l 3S001 for 82mm soil pipe
l 4S001 for 110mm soil pipe
l 6S001 for 160mm soil pipe
Testing
OSMA Fire Stop Seals have been tested
to BS 476: Part 20 at the Warrington Fire
Research Centre. All sizes met insulation and
integrity criteria for up to 4 hours.
Applications
OSMA Fire Stop Seals are suitable for
maintaining the fire resistance of:
l Masonry walls and concrete floors which
are penetrated by plastic pipework
forming part of a drainage or ventilation
system
l Timber floor constructions with ceiling
lining which has at least one hour fire
resistance rating
OSMA Fire Stop Seals can be fixed
before or after the installation of the pipes
and operate horizontally or vertically. For
horizontal pipework where there is a fire risk
from BOTH sides of the wall, the unit should
be installed within the thickness of the wall
or, if this is not possible, one unit should be
fitted to each side of the wall (see Fig. 37).
OSMA Fire Stop Seals are suitable for
all types of new or refurbished buildings,
especially residential flats, apartments,
offices, hospitals, and schools.
They must be carefully fitted strictly in

Materials: Properties and Performance
Heat resistance
Pipes and fittings manufactured from
PVC-U or ABS:
OSMA Soil systems and ABS Solvent Weld
Waste system: OsmaWeld Suitable for use
with intermittent discharges of water up to
90°C.
Pipes and fittings manufactured from
PVC-C or Polypropylene:
PVC-C Solvent Weld Waste system, PP
Push-Fit Waste systems (to BS EN 1451-1
and BS EN 1566-1) and V-Joint Traps
Suitable for use with intermittent discharges
of water up to 100°C.
PVC-U and ABS overflow pipes and
fittings:
Solvent Weld Overflow system:
Must not be used where hot water
discharges are likely to occur.
Polypropylene overflow pipes and fittings:
PP Push-Fit Overflow system:
May be used where intermittent hot water
discharges are likely to occur. However,
they must not be used with combination hot
water cylinders and feed tanks.
Chemical resistance
OSMA Soil, Waste and Trap systems are
unaffected by normal domestic effluent,
detergents, cleaning fluids and a wide range
of chemicals. Chemical effluent containing
solvents should not be disposed of through
PVC-U and ABS Waste systems.
For commercial and industrial applications,
consult BSCP 312: Part 1: 1973 Code of
Practice for plastic pipework. This provides
comprehensive information on chemical
resistance to plastic pipework.
Painting
OSMA Soil, Waste and Overflow pipes
and fittings are self-coloured and corrosion
resistant. They may, however, be painted
with normal household paints if an alternative
colour is required. Oil-based gloss paint
is the most suitable for this purpose. For
best results, slightly abrade the surface with
sandpaper and clean thoroughly before
painting.
Timber preservatives
If soil or waste pipes and fittings are to be
installed externally and fixed to timber fascias
or boards treated with timber preservatives,
the preservatives must first be allowed to dry
out prior to fitting. Refer to manufacturers’
recommendations.
Biological attack
Normal pollutants in the atmosphere will not
affect Soil, Waste or Overflow systems. They
are also unaffected by fungi, moss, lichen,
moulds or bacteria.
Physical attack
If pipework is installed internally or externally
in areas likely to suffer attacks by vandals,
the suitability of the material should be
questioned. In such a situation, Solvent Weld
systems are less likely to be dismantled than
Ring-Seal or Push-Fit systems. However,
unlike cast iron or copper systems, plastic
has no scrap value and is therefore less likely
to be targeted.
Design l Materials
Ultra violet light
PVC-U and PVC-C pipework has superior
resistance to the effects of UV light and,
although it may fade slightly after many years
of exposure to strong sunlight, its integrity is
unaffected. It is recommended that externally
installed ABS and PP pipework be painted
with an oil-based gloss as a protective
coating against long exposure to sunlight.
Radon gas resistance
Soil pipes and fittings are unaffected by
radon gas when used as part of a ventilation
system designed specifically for radon gas
extraction. For connections made within a
building, the use of solvent weld joints is
advisable. For further information on radon
gas, contact the BRE Radon Hotline on
01923 664707.

Design l Handling & Storage
Handling and Storage
Handling
Care should be taken when handling pipe
and fittings. Excessive scratching or scoring
harms the appearance and can also affect
the joint sealing.
Take extra care when handling pipe and
fittings in wintry conditions. Cold weather
reduces the impact strength of plastics. Use
nylon belt slings, or forklifts with smooth
forks, for mechanical unloading of block
bundles. Metal slings, hooks or chains must
not come into contact with pipes
(see Fig. 38).
Load and unload loose pipe by hand. Avoid
using skids. When loose pipes have been
transported one inside the other, always
remove the inner pipe first.
Fig. 38 Unloading of block bundles
Storage
Always store pipe on a reasonably flat
surface free from sharp projections.
Block bundles
Block bundles can be stored up to 3m high
without extra side supports or bearers. Block
bundles will remain free-standing when cut.
Take care when releasing bundles as the
straps are under considerable tension and
may flail when cut.
Loose pipes
Loose pipe requires side supports at least
every 2m. These supports should consist of
battens at least 75mm wide. Ideally, support
loose gutter or pipe uniformly throughout
its entire length. If this is not possible, place
timber supports at least 75mm wide at 1m
maximum centres beneath the pipe (see Fig.
40) Stack different size pipe separately, or, if
not possible, stack with larger diameters at
the bottom.
Maximum stack size: 7 layers or 2m high
(see Fig. 39).
Stack Socketed Pipe with sockets
protruding and placed at alternate ends to
ensure pipe is evenly supported.
Fittings
Store fittings supplied in plastic bags
away from direct sunlight. If this is not
possible, open bags to prevent a build-up of
temperature.
Fittings in cardboard packaging (e.g. Fire
Stop Seals and Air Admittance Valves)
should be stored under cover until required.
Store degreasing cleaners, silicone lubricant,
solvent cement and fillers in a cool place
away from any heat source and out of direct
sunlight.
Safety
The relevant regulations detailed in the
Health and Safety at Work Act 1974 must be
adhered to on site.

Pipe Cutting and Jointing
Pipe cutting
Pipe may be cut on site using a fine-toothed
hand saw.
PROCEDURE
1. Cut pipe cleanly at right angles to its axis
(see Fig. 41)
2. De-burr the cut end with a scraper if the
cut end is to be inserted into a ring-seal
or push-fit joint
3. Chamfer the spigot end: this is essential
to ensure that the sealing ring is not
displaced during insertion
Ring-seal/push-fit jointing
PROCEDURE
1. Ensure any pipe cut on site is also
chamfered
2. Check that the sealing ring is properly
seated in its housing in the socket of the
fitting
3. Ensure all components to be joined are
dry, clean and free from grit or dust. Note
any deep scratches on the pipe or fitting
spigot as these may prevent the sealing
ring from forming a water tight seal
4. Lubricate evenly around the pipe or
fitting spigot end with Silicone Lubricant
4S391. Do NOT lubricate inside the
socket. Do NOT use washing up liquid
as a lubricant. If using 400ml can 4S392,
spray the lubricant onto the spigot and
not the ring seal. The spigot can then be
inserted into the socket
5. Correctly align the components to be
joined
Installation l Pipe Cutting & Jointing
6. Push the pipe or fitting spigot fully into the
socket. Mark the pipe or fitting spigot at
the socket face and then withdraw it by
a minimum of 12mm to allow for thermal
expansion (see Fig. 42)
7. Make a subsequent check to ensure
that the expansion gap is not lost during
further installation work

PROCEDURE
1. Before using any solvent based cleaners
or cement:
– Read instructions on the can
– Ensure there is sufficient ventilation
2. Make sure pipe or fitting spigot and
solvent weld socket are dry, clean and
free from grit or dust
3. Clean surfaces of spigot and socket with
Degreasing Cleaner Nº.1 4S379/ 380.
Apply liberally using a clean non-synthetic
rag or absorbent paper
4. Apply one coat Solvent Cement
Nº.2 4S383/384/385. Apply an even
coat to both surfaces using the applicator
provided or a paint brush. Stroke the
cement ALONG and not around the
surfaces
5. Immediately insert pipe or fitting spigot
fully into the socket (see Fig. 43). Each
solvent weld joint MUST be completed
within 1½ minutes
6. Hold for 20-30 seconds. Remove any
surplus cement from the mouth of the
socket
7. The joint may be handled after 10
minutes and commissioned after 24
hours
NOTE: Complete soil stacks can be pre-
fabricated using the OSMA Solvent Weld
system. This may be useful where identical
designs are required for multiple projects.
Safety
When making solvent weld joints it is
essential to observe normal safety rules for
handling solvent:
l Never smoke or bring naked flames near
the area of work
l Work in a well ventilated area to avoid
inhaling fumes
l Close the solvent container after use and
store in a cool area
l Do not allow solvents or cleaners to come
into contact with skin
Refer to COSHH Regulations (Control of
Substances Hazardous to Health) where
applicable.

OsmaVent 110
The OsmaVent 110mm Air Admittance
Valve 4S304/4S306 (AAV 110) is designed
for venting 110mm soil pipe stacks. It
prevents siphonage and protects traps by
allowing air into the discharge pipework
without allowing foul air to escape.
Soil Stack Ventilation
See page 98 for details on ventilation.
For connecting to 110mm pipe
PROCEDURE
1. Cut the 110mm PVC-U pipe square to
its axis
2. Clean and remove swarf
3. Push-fit the valve into the pipe end (no
lubrication necessary)
4. To achieve the A1 rating -20°C the 4S304
will require the top half of packaging to be
fitted over it.
5. To achieve A2 rating 0°C, the 4S306
does not require insulating when used in
the loft
For connecting to 82mm pipe
PROCEDURE
1. Remove rubber connector from AAV
2. Solvent weld AAV onto short length of
82mm pipe
3. 82mm pipe should be connected to the
soil stack via a ring-seal fitting to allow the
AAV to be easily removed for access to
drainage system
Venting of stub stack
If a stub stack access assembly, to which
ground floor cloakroom appliances are
commonly connected, is discharging into
a non-vented nearby drain, it will require
venting eg. via AAV.
The OSMA 110mm Air Admittance Valve
4S304 may be used to vent a stub stack in
the following circumstances:
– If the crown of the WC trap is more than
1.5m above the drain invert
– The topmost connection to the stack
is more than 2m from the drain invert

Making threaded connections
PROCEDURE
1. To help prevent capillary action, wrap
PTFE tape around the male thread prior
to screwing into the threaded socket or
screwing on the threaded nut
2. Screw in hand tight plus a quarter turn.
Do not over tighten, as damage may
occur
NOTE: Do NOT use linseed oil based jointing
compounds with plastic components
Making Bath Trap Overflow connections
PROCEDURE
1. Unscrew rose terminal and position in
hole in bath
2. Fit rubber washer over threaded spigot
on the outside of the bath. Screw into
socket of overflow connections
3. Hand tighten and finish with a quarter
turn with spanner or wrench
Bath Trap and WasteFlow Unit 5V859
Used with the Bath Trap, the WasteFlow
Unit provides a bath overflow as well as a
neat and convenient means of disposing of
overflow from both cold water storage and
WC cisterns.
Use of the Wasteflow Trap eliminates
the need for external overflow pipes and
possible damage to walls through dripping
overflows.
Water overflowing from the storage or WC
cistern enters the bath through the overflow
grating. This creates a nuisance value
and indicates that the ball valve requires
attention.
The design of the grating ensures that
any water that discharges drips clear of
the sloping end of the bath and is more
noticeable. This water may then be let out of
the bath via the waste outlet or, in the event
of the bath filling, back through the bath
overflow proper, finally passing through the
waste trap.
A weir device is incorporated into the
manifold unit as a safeguard against water
flowing back along the overflow pipe. If the
bath fills with water, the overflow discharge
will be prevented from entering the overflow
pipe by the ‘weir’ and pass safely down the
flexible hose into the bath trap.

NOTE: Bending of pipe in excess of 19mm
[¾”] is not recommended
Overflow termination options
After penetration of the building wall,
overflow pipe ends on the exterior should be
terminated in one of the two following ways:
l Splay cut end
OR
l Fit with a 90° Tee 1E190 to inhibit entry of
freezing draughts
Tundish – for overflow in basement areas
Unlike overflow systems above ground level,
excess water from tanks or cisterns located
in basement areas cannot be carried to
a visible point on the building exterior. To
ensure that any overflow is visible in areas
of a building below ground level, install
Tundish 1O149 along the vertical route of
the overflow pipe. This should be placed as
near as possible to the cistern or tank, and
in a visible position. A 25mm air gap should
be allowed between the end of the overflow
pipe and the rim of the Tundish in order to
identify the source of the discharge.
IMPORTANT NOTE: Do NOT connect
overflow pipework to soil and waste
discharge stacks or branches
