The 1st steps to drains pipes installation
The most important thing that you have to care about while taking on any DIY plumbing and sewage work are the Local Authority rules which they actively supervise.
Detailed plans of any changing or installing of sewage in your home will have to be submitted, and expect ongoing inspections until its completion to ensure that the work abides by the regulations. However you don’t need to inform them if you are just replacing some damaged parts.
When rain falls on your house and property, it runs across as surface water and has to be drained properly. It can drain out through a soakaway, watercourse, surface water sewer or, especially in older houses, into the dirty water drainage pipes. 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. However with the new drainage systems, the foul and the surface water can be kept apart. To comply with modern planning regulations you should always make sure that the foul water and surface water sewage system do not connect. If you have doubts about your house’s drainage system, you can get help from the Building Control Department before you begin any work.
Designing the path of the waste passages will be your first task. The route should be as short and straight as possible, this will help to reduce future maintenance problems and costs. If the pipe slope is excessive, your joint alignment may fail. You can calculate the fall of a drain over a distance using a surveyors site level. A hosepipe filled with water from an established datum point can be used if you don’t have a surveyor’s site level.
Be very careful not to excavate too close to your building, as you may undermine the foundation and cause a structural collapse. The foundation of the building should not be undermined by your digging if the waste pipe runs parallel to it.
While installing a new sewage system make sure that you do not dig too long before laying the pipe. You should attempt to get the pipes laid as soon as possible and, after inspection and checking, you should back fill the trench.
Depending on the depth and soil conditions, the trench may require support. Avoid risks when working in the ditch. If in doubt add support to the trench to prevent it from collapsing. The ditch should be narrow, but spacious enough for people to work with any required tools. The bottom of the ditch must be smooth and clean, free of any objects that make it uneven such as stones or bricks. If the exiting material is not suitable then you may need to import a suitable material for the base of the ditch.
Pipework must be uniformly supported by the soil bed, and not by stones or bricks haphazardly placed underneath the pipes. Even if used for just a temporary support this can damage the pipe. Consolidate the bottom with a small roller or rammer and provide grooves in the bed to support the joints properly. The entire drain pipe system has to be uniformly supported by the soil bedding.
It is very important that the design of the drainage system should be constructed in such a way that all parts of the pipework are accessible to a set of drain rods for future maintenance. The drains should therefore run straight between two points to ease the passage of the drain rods. In case of any change in the direction of the pipework it should be provided with an inspection chamber for allowing drains rod access.
