The task list plan for drain pipes set up
Local building laws and procedures have to be complied with whenever you carry out drainage or pipework repairs and fitting by yourself.
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. In many situations when you are simply replacing damaged parts, there is no need for the local authority to be advised.
When rain falls on your house and property, it runs across as surface water and has to be drained properly. In older properties this can discharged into a foul water sewage system whereas in other properties this can discharged into a soakaway, watercourse or a surface water sewer. 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. With more contemporary systems, however the foul water and surface water is kept separate, this is a more recent development. It is extremely important to ensure that you do not connect foul water to a surface water drainage system. If you are unsure about the drainage system around your house get advice from the Building Control Department before you start any work.
Before you begin, you will need to plan the route 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 blockages. Steep pipes should be averted during the path design. You can calculate the fall of a drain over a distance using a surveyors site level. By establishing a datum point and using a hosepipe filled with water to establish levels you can calculate the fall from the datum in a situation when do not have one of these measures available.
Be very careful not to excavate too close to your building, as you may undermine the foundation and cause a structural collapse. Keep the drain pipe excavation at a uniformly safe distance from the home face to avoid damage to the foundation.
The pipes should be laid before too long a trench is dug as a new trench can be unstable. You should attempt to get the pipes laid as soon as possible and, after inspection and checking, you should back fill the ditch.
Because of different depth and soil conditions the trench will probably need to be supported. You should avoid any risks with this project. 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 trench as narrow as possible, but allow room to work in the trench. Protruding stones or bricks should not be left in the base and it should be cleaned to provide a smooth, regular surface. The base should be good so you may need to import material if the existing soil structuire is not up to the mark.
For pipe support do not use bricks or other hard materials in the ditch. This should not be used as employing this type of material as a temporary or permanent pipe support will damage the pipe. The base should be tightly packed in the appropriate manner with holes carved out to fit in the protruding pipe connections. The entire drain pipe system has to be uniformly supported by the soil bedding.
It is very important that the design of the sewage 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. Always make sure that rodding access is allowed in an inspection chamber at any point where the direction of the pipework changes.
