Structured wall systems 

Marley Quantum was developed in 1991. The objective was to maximise the structural performance of plastic pipes and to produce 

a pipe that was lightweight and easy to install on site. This in turn reduces the overall installation cost.

Key components 

The Marley non-return valve (USW120) 

The Marley non-return valve is a simple and effective way to eliminate backflow 

through drainage systems. The flap in the valve opens to allow discharge. In a 

potential flood situation, the rising water levels seal the flap shut, alleviating the 

risk of the water backing up into a property. 

The internal profile is designed to avoid any interrupted flow and provides full access 

for pipe cleaning or rodding. (see below ground price list, page 39) 

Non-return valve (USW120) 

Bottle gully (UG50) 

Ideal for new or replacement installations. Accepts waste and rainwater pipes. 

A fully rotating gully body allows the outlet to face the required direction 

of the drain connection. 

A removable rubber plug provides access for rodding.

Design 

Statutory requirements 

The following standards deal with drainage design: 

 

 

and Sewers. 

The design and layout of drainage and sewerage systems 

should comply with The Building Regulations and Water 

Authority Specification. Reference should also be made to the 

Sewers for Adoption manual. 

The following information is provided only as a general 

guide to good practice for the design of underground 

drainage systems. For full details please consult the relevant 

documents referred to above. 

Means of access 

Access is required to drainage installations for testing, 

inspection and removal of debris. Access to drainage allowing 

rodding in both directions can be provided by inspection 

chambers, manholes and other access fittings. Rodding eyes 

provide access for clearance of debris in the direction of flow 

only and should thus be used in conjunction with an access 

chamber or manhole at a point downstream. 

No part of the drain or sewer should be more than 50m 

away from a manhole. The distance between points should 

therefore not exceed 100m. 

For full guidance as to provision of access, reference should 

be made to BS EN 752 2008. The table below details the 

maximum spacing of the access points as detailed in the 

above standard.

Pipe laying 

The following information is based on the recommendations in BS 5955: Part 6 

 

 

guide to good practice in the selection of bedding and backfill materials for 

Marley solid wall and Quantum underground drainage systems. 

Excavation 

Trenches should not be open for 

extended periods in advance of pipe 

laying and should be backfilled as soon 

as possible. It is essential that the sides 

of the trench are adequately supported 

during pipe laying. Trench widths 

should be as narrow as is practicable 

but not less than the pipe diameter plus 

300mm to allow adequate sidefill to 

be placed. Deeper excavations should 

ideally incorporate a sub-trench in 

accordance with the diagram opposite.

BS EN 1610 bedding construction type B 

(see drawing opposite).

Where the backfill above the pipe 

contains stones larger than 40mm or 

where the pipework is deeper than 2m 

in poor ground, the granular material 

must extend at least 100mm above 

the pipe crown. Alternatively, backfill 

material can be graded to eliminate 

stones exceeding 40mm and this 

selected material used for the first 

300mm above the pipe. 

When the pipes are to be laid 

in rock, compacted sand or gravel, 

or in very soft or wet ground requiring 

mechanical means of trimming, 

the bedding should be a minimum 

of 100mm.

Shallow domestic drains 

Pipes laid at depths less than 600mm and which are not 

under a road should, where necessary, be protected against 

damage by placing over them a layer of concrete, paving slabs 

or similar. A minimum 75mm cushioning layer of granular 

material must be laid between pipes and the slabs or concrete. 

Where drains are laid in fields, additional protection may 

be required from heavy vehicles and equipment. It is 

recommended that the installation is carried out with 

a concrete slab spanning the trench as shown for drains 

under private roads (right). 

Drains under solid ground floors 

Drains often have to be laid under buildings in order to connect 

sanitary pipework which has been positioned some distance 

from the outer walls. Where this occurs, deep hardcore within 

the foundation boundaries should be compacted first. The 

trench for the pipe should then be excavated and suitable 

material employed for the bedding and backfilling operation. 

If trenches are dug from original ground, pipes may be laid 

and surrounded as necessary before the top layer of hardcore 

is formed. Where a pipe passes through a wall or foundation 

of a building, a lintel or sleeve should be built-in to provide 

clearance around the pipe. 

Concrete bed & surround 

 

accommodate ground movement and other differential 

settlement that may occur under normal conditions. 

Therefore, the use of concrete bed and surround is not 

recommended and only under special circumstances, at very 

shallow cover depths or where it is necessary to safeguard 

foundations, should it be used. Where the use of concrete 

bed and surround is unavoidable, it is recommended that 

pipes are laid in 3 metre lengths and a compressible board 

is shaped to fit around each joint. Pipes should also be 

wrapped with polythene to prevent the ingress of cement 

slurry into ring seal joints.

by simply cutting a riser, between the 

ribbed sections, to the desired height 

using a fine tooth saw.

During the installation stage and 

prior to backfilling, it is recommended 

that chamber riser retaining clips

backfilling operation. 

Sidefill material should extend to just 

below ground level and the cast iron

Making the connection 

Stub waste connections 

Isolated ground floor sanitary 

appliances are frequently supplied with 

their own 110mm drain in the form of 

an oversized and unventilated branch. 

There are two methods of connecting 

waste pipework direct to drain. The 

SRM402 reducer may be used and 

solvent welded onto a plain spigotupstand 

of pipe. 

With the SE41 reducer a flexible 

connection is provided at floor level 

as this fitting push fits into a ring seal 

socket. Standard Marley boss adaptors 

are used with both types of reducer.

Rainwater pipe 

connections 

External rainwater pipes usually 

connect direct to the drain or, 

depending on the design of the 

sewerage system, via a gully trap. 

Where rainwater pipes connect 

directly to a drain and are of different 

sizes, a suitable reducer and adaptor 

fitting will be required.

systems are the same and therefore 

direct connection may be achieved 

without an adaptor.

by hand or by using a timber block 

and lever on the other end of the pipe. 

Connection to 160mm 

solid wall pipe 

All 150mm Quantum sockets 

have been designed for use with 

Quantum pipes and 160mm solid 

wall pipes to BS EN 1401: 2000. 

To adapt a Quantum fitting to 

accept 160mm solid wall drainage 

 

UR61T must be fitted to the end 

of the socket to enable a connection 

to be made, as shown above. 

Quantum couplings, bends, branches 

and reducers have an all socket 

configuration and jointing these to 

Quantum pipe is achieved in the same 

way as described above.

The UMA45 adaptor may be used to 

connect 150mm Quantum pipe to 

Densleeve or Hepsleeve 188mm outside 

diameter clayware pipe. 

The adaptor is designed to allow Quantum 

pipe to be jointed with clayware pipe 

using a standard clayware pipe coupler. 

Installation procedure 

1. Remove factory fitted ‘T’ seal from 

adaptor socket. 

2. Fit Quantum seal on the pipe in 

the 10th corrugation from the end 

of the pipe ensuring the seal is 

correctly handed. 

3. Lubricate the seal and inside the 

socket of the adaptor. Push the 

adaptor over the pipe, ensuring the 

pipe passes completely through the 

adaptor until the end of the pipe 

aligns with the end of the adaptor. 

4. Lubricate the adaptor spigot 

and push into the clayware pipe 

coupler up to the central register. 

Quantum to thin 

wall clayware 

The same adaptor can also be used 

to connect 150mm Quantum pipe 

to Hepsleeve or Supersleeve 178mm 

outside diameter clayware pipe. For 

this application the end spigot of the 

adaptor is first removed using a fine 

tooth saw. The remaining section of the 

adaptor is then suitable for connecting 

directly into a standard polypropylene 

clayware pipe coupler as shown above. 

The installation sequence for 

this application is similar to that 

previously described but the seal is 

fitted on the Quantum pipe in the 6th 

corrugation from the end of the pipe 

to take into account the shortened 

length of the adaptor.
