The best steps to drain pipes set up

Before executing any DIY plumbing and sewage, you should first take into consideration the rules issued by your Local Authority.

The local authority will definitely require you to submit complete drawings of the proposed changes or replacement of your existing drain and sewage system to ensure that your work is in conformity with local rules. However you do not require authority approval for replacement of failed joints or cracked plumbing and drains pipes.

The water which you see on the surface is basically rainwater. This can discharged into a soakaway, watercourse, surface water sewer or, particularly in older properties, into the foul water sewage system. To stop any nasty odours emanating from the drains a combined system will discharge the surface water into the foul water drains by way of the gully traps. However with the new sewage systems, the foul and the surface water can be kept apart. Rainwater and foul water sewage should not be interconnected, however convenient it may seem. The Building Control Department is your first point of contact before you start any work if you are not familiar with your home’s drainage system.

Of course, the first thing you should do is plan the layout of the waste pipes. The basic thing which you have to care about is to keep the route as straight and short as you can while designing the route of a waste or soil pipe, this will help to reduce the likelihood of stoppages. You must avoid making your pipe runs too steep. Use a surveyor’s leveling tool to set out the slope of the drain trench. In the absence of one of these, create a datum point and set levels with a hosepipe filled with water and compute the fall from the datum in this manner.

The stability of the existing house is of prime importance it should be not compromised while the drain ditch is being installed so check you are not impacting on the existing structure. The substructure of the building should not be undermined by your digging if the drain runs parallel to it.

While installing a new sewage system make sure that you do not dig too long before laying the pipe. The pipes should be laid quickly and the trench back filled after the system has been examined thoroughly and tested as required.

Depending on the depth and soil conditions, the ditch may require support. You should avoid any risks with this project. Be on the safe side and secure the sides of such risky trenches by propping with sheets or boards. Keep the ditch as narrow as you can but of course make sure that there is enough room to work in the ditch including any plan, machinery or tools you require. The base of the trench should be clean and even and free from protruding stones or bricks etc. If the existing soil is too weak or clayey, you should place and compact a layer of firmer soil at the base of the trench to prevent later sinking.

Never use bricks and/or other hard materials to support the pipe in the trench. This will damage the pipe and must never be used as temporary or permanent support. For accommodation of the joints in the pipes,the bedding should be compacted in a regular way with hollows made a appropriate points. The entire drain pipe system has to be uniformly supported by the soil bedding.

Make sure that your plans are made in such a way that drain rods are within reach of every part of the network of pipes. The drains should therefore run straight between two points to ease the passage of the drain rods. Inspection chambers have to be provided at any sudden changes of direction or level, so that drain rods can be inserted easily.

DIY plumbing and sewage is certainly within the limits of most DIY enthusiasts.
