Do you acknowledge the first actions in sewage installing
Before executing any DIY plumbing and drainage, you should first take into consideration the rules issued by your Local Authority.
Detailed plans of any changing or installing of drainage in your home will have to be submitted, and expect ongoing inspections until its completion to ensure that the work abides by the rules. If you are simply replacing damaged sections of the sewage, in most circumstances they do not need to be informed.
The water which you see on the surface is basically rain. An earlier method was to directly discharge this surface water into the sewage drains, but modern homes use a surface water sewer or watercourse or soakaway to drain or absorb rainwater. 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’s absolutely crucial that you keep the dirty water sewage system apart from the one for surface water. You should get advice from the local authority Building Department before you start any work in a situation when you are not sure about the sewage system around your house.
Of course, the first thing you should do is plan the layout of the waste pipes. Have an eye to future maintenance when you design the sewage system and always try to keep the waste or soil pipe as straight and short as you can when you are devising the layout. If the pipe slope is excessive, your joint alignment may fail. With the help of a surveyor’s site level, you will be able to determine the fall of a drain over a distance. 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 house, 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 drain pipe runs parallel to it.
The pipes should be laid before too long a ditch is dug as a new trench can be unstable. Excavate a part of the sewage system, install and test the pipework, and then back fill and compact the earth before moving on to the next part.
Because of different depth and soil conditions the ditch will probably need to be supported. Take he utmost care when doing this work. If in doubt add support to the trench to prevent it from collapsing. Keep the trench 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. Protruding stones or bricks should not be left in the base and it should be cleaned to provide a smooth, regular surface. If the material at the base of the trench is not appropriate then you might have to bring in new material.
Never use bricks and/or other hard materials to support the pipe in the trench. 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. For the complete pipe length you have to provide a continuous and uniform support.
The drainage system should be designed in a way that pipework remains accessible to drain rods should drainage maintenance work be required. Thus, a drain route must be as straight as possible between any two points. In case of any change in the direction of the pipework it should be provided with an inspection chamber for allowing drains rod access.
DIY plumbing and sewage is certainly within the limits of most DIY enthusiasts.
