The task list plan for drains pipes fitting

Before you undertake DIY plumbing and drains work it is essential to understand the national rules and rules formulated by the local authority.

You will have to present detailed plans for the proposed sewage work when you are changing existing sewage system or installing a new sewage system, and also need regular inspections to be undertaken to ensure that the plans are following the local building regulations during progressing each phase of the work. In most cases they do not need to be notified for a simple replacement of broken parts.

Surface water is basically rain. In older properties this surface water can find its way into the foul water sewage system, but more generally it can also end up in a watercourse, surface water sewer or soakaway. In a system combining both functions, the rainwater pipes clear out into the dirty water drains through the gully traps that prevent fetid air from sneaking out of the drains. Nowadays hygiene and recycling considerations have led to a mandatory separation of surface water and sewage water. It’s absolutely crucial that you keep the dirty water sewage system apart from the one for surface water. The Building Regulation Department will be able to guide you on any details or procedures you may require for repairs or replacement of your drainage.

To properly prepare the plans and get local authority permission to commence work there is a need for you to plan the route of the waste pipes before you begin. Sewage pipes must be aligned as straight as possible, with inspection chambers at short intervals. The pipes should run straight with a gentle incline. A surveyor’ site level should be used to work out the fall of a drainpipe. Or just fill a transparent hosepipe with water and use the water level at the two ends to mark the required fall from the starting point.

Be very careful not to excavate too close to your house, as you may undermine the foundation and cause a structural collapse. 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 ditch back filled after the system has been examined thoroughly and tested as required.

Depending on the depth and soil conditions, the trench may require support. Avoid risks when working in the trench. If you have any worries, you should support to the trench to reduce any risk of collapsing side walls during the building phase. Keep the ditch as narrow as possible, but allow room to work in the trench. The bottom of the ditch must be smooth and clean, free of any objects that make it uneven such as stones or bricks. You may have to bring in the right type of material for the bottom of the trench if the one that’s already there is not proper.

For pipe support do not use bricks or other hard materials in the trench. This should not be used as support for the short or the long run because it will damage the pipe, the pipe needs to be fully supported over its full lenght. The bedding should be made compact to fit around the pipe joints. 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. As a general rule, any change in direction of the pipework should be provided with an inspection chamber to allow rodding access.

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