The best strides to drain pipes installing
Before starting any plumbing and drainage work yourself you should find out about any Local Authority rules that relate to your area.
If you are considering altering your existing drainage, or installing a new drainage system you will almost certainly need to present some detailed plans of the work that you intend to undertake and it will need to be inspected as the work progresses making sure that it complies with the local building rules. If you are simply replacing damaged sections of the sewage, in most circumstances they do not need to be informed.
Surface water is basically water from rain and is handled differently from dark waste water in a modern sewage development. 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. The rainwater pipes in combined drainage systems empty their discharge into the foul water drains through gully traps, this prevent foul air from escaping outside creating odours. Nowadays hygiene and recycling considerations have led to a mandatory separation of surface water and sewage water. It is extremely important to ensure that you do not connect foul water to a surface water sewage system. 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 drainage system around your house.
Before starting your work, finalise the routes the waste pipes would take. Keeping the path as straight and short as possible will be the main concept behind the design of the waste passageways or pipes. Steep pipes should be avoided during the path design. Use the surveyor’s site level to calculate the drain fall over the complete system. 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.
You will need to see to it that you do not impact on the stability of the building whilst installing your drain ditch. If you are laying a drainage run parallel to the building, you must ensure that any foundations are not undermined.
While installing a new drainage system make sure that you do not dig too long before laying the pipe. Get the pipes laid quickly and, as soon as they have been tested, fill the trench back in.
The trench may need to be supported depending on the depth and soil conditions. It is no advisable to not take any risks. If you are not sure prop up the trench anyway to prevent it from falling. The trench should be narrow, but spacious enough for people to work with any required tools. The bottom of the trench must be smooth and clean, free of any objects that make it uneven such as stones or bricks. You may need to import a suitable material for the base of the ditch if the existing material is unsuitable.
The pipe present in the ditch should not be supported using bricks or other such materials. In fact they should be never used as support as they can damage the pipe as they will focus pressure into a small area. The material used for bedding should be firmly compacted down with a depression created to allow the joints in the pipes to fit easily. The entire drain pipe system has to be uniformly supported by the soil bedding.
When designing your sewage system, it is important to make all parts of the pipework reachable via a set of drain rods should a blockage occur. This need for drain rod access can be easily achieved by keeping the pipeline straight and in short sections. Always make sure that rodding access is allowed in an inspection chamber at any point where the direction of the pipework changes.
DIY plumbing and drainage is within the reach of many DIY fans if you follow these simple rules.
