Drainage Installation
Most new domestic drainage application will use plain ended pipes, rather than socketed pipes. Plain ended pipes are those that have identical ends and are joined by means of a coupling. Socketed pipes have identifiable ‘male’ and ‘female’ ends, and must be laid with the ‘female’ end pointing upstream. Many older properties will have socketed clayware drains, typically of imperial dimensions. We stock a large range of flex seal adaptors that enable modern plastic pipes to be connected onto the older clayware pipes and fittings.
The Benefits of Plastic drainage Pipes over clay.
Plastic pipes are much lighter and therefore easier to handle than clayware, and can be easily cut with a hacksaw, whereas clay is heavy and needs to be cut with special pipe cutters or a power-saw. Clay is also relatively fragile meaning care must be taken to avoid breakages.
Bedding detail for plastic pipes.
Plastic drainage pipes must be surrounded by a selected small gravel or pea-shingle.

Pipe Laying Basics
Pipes should be laid in straight lines to a steady gradient. A taut string line, sight rails or a laser line is used to ensure accuracy in alignment and level. The bedding is prepared in advance.
Pipes should be laid on a full bed of granular material and NOT propped up on bricks, bits of stone etc. The pipe should be consolidated into the bedding or have the bedding packed beneath it until it is at the correct alignment and as indicated by the guide line (string or laser).
Laying Plain Ended Pipes
As noted above, many drainage systems are termed Plain-ended. This refers to the pipes, which have no integral socket and rely on couplings to join together pipes and fittings. This type of system has some advantages over socket and spigot types, in that the separate couplings offer greater flexibility and off-cuts from pipes can utilised by simply adding a coupling to each end.
The ends of the pipes are chamfered when new. Pipes and fittings that have been cut may need to have the cut end chamfered on-site; cut ends to plastic pipes can be easily chamfered by means of a file.
With all plain-ended systems, the basic laying procedure is the same:
- lubricate end of pipe/fitting and coupling*
- slide coupling onto pipe/fitting
- lubricate receiving end of coupling and end of next pipe/fitting
- slide next pipe/fitting into coupling
- repeat as required
*using pipe lubricant (click to view)
Cutting Pipes
Although there is a massive range of fittings and accessories for the various drainage systems, it is inevitable that, at some point, a length of pipe or a fitting will need to be cut down to enable it to be fitted.
Plastic Drainage pipes are simply cut to size using a handsaw or full-size hacksaw, and then using a file to chamfer the newly-cut end.
It is important that any cut is square to the rest of the pipe or fitting. One simple way of achieving this with straight pipes is to use a sheet of newspaper wrapped around the pipe. As long as the paper is snug to the pipe, its edge will give a fairly accurate guide to square and a line can be marked with chalk, slate or similar.
Gradients and Cover
The minimum cover plastic drainage is:
- 600mm in fields / gardens
- 900mm beneath light roads / drives
Note: If minimum cover cannot be achieved, the pipework will need to be encased in concrete.
The minimum gradient for surface water drainage (rainwater) is 1:100
The minimum gradient for foul water drainage is 1:40 (1:80 if a toilet is connected)
Fittings and Access points
There is a huge range of fittings available for all types of drainage systems. These include gullies, hoppers, traps, bends, and junctions as standard items, as well as access chambers, rodding eyes and inspection chambers which are designed to grant access for inspection and/or maintenance.
