The Benefits of Plastic Drainage Pipes
- Lighter
- Easier to handle
- Easy to cut
- Difficult to Break
- Less fragile
For those that aren’t used to Drainage Products lets be honest, it can be a little confusing as to which drainage fitting you should be choosing, see our handy little no-jargon proof guide below on the different types of Drainage Pipes and Fittings.
Plain Ended Pipes or Socketed Pipes?
It’s common now for most new domestic drainage applications to 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 Flexseal adaptors that enable modern plastic pipes to be connected onto the older clayware pipes and fittings.
Bedding detail for plastic pipes.
Plastic drainage pipes and fittings must be surrounded by a selected small gravel or pea-shingle.
For further detail consult Approved Document H of the Building Regulations.
Pipe Laying Basics
You may think it sounds basic but drainage pipes should ideally be laid in straight lines to a steady gradient. A taut string line, sight rails or a laser line can be used to ensure accuracy in alignment and level. The bedding should be prepared in advanced.
Drainage 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 mentioned above most drainage systems are termed Plain-ended. This refers to the pipes, which have no integral socket and rely on couplings to join together the drainage 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, helping make the job as cost effective as possible (which never hurts!)
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 drainage 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
Cutting Pipes
Although there is a massive range of drainage 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)
Drainage Fittings and Access points
There is a huge range of fittings available for all types of drainage systems. The se 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.
