Setting Up a sewer, do this first off
The most important thing that you have to care about while taking on any DIY plumbing and sewage work are the Local Authority regulations which they actively monitor.
If you are considering altering your existing sewage, or installing a new sewage 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 regulations. In many situations when you are simply replacing broken parts, there is no need for the local authority to be informed.
Whatever water we see on the surface around your home is usually rain. It can drain out through a soakaway, watercourse, surface water sewer or, especially in older houses, into the dirty water drainage pipes. Air escape from the drains is stopped when rainwater pipes are discharged into the foul water drains through gully traps in an older combined system. However, modern systems are designed to keep the foul water and the surface water apart. To comply with modern planning rules you should always make sure that the foul water and surface water drainage system do not connect. 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.
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. 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. 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 house whilst installing your drain ditch. Similarly, take care of the foundations when laying a waste pipe that runs alongside the home.
Do not dig the trench too long before laying the pipe when installing a new drainage system. Make sure that you get the pipes laid as quickly as possible and then backfill the trench as soon as the system has been inspected and tested.
Weak soil may require that you shore up the walls of the excavation, particularly for deeper trenches. Take he utmost care when doing this work. If you are not sure prop up the ditch anyway to prevent it from falling. The trench should be narrow, but spacious enough for people to work with any required tools. The trench base must be smooth and clean, there shouldn’t be any bricks or protruding stones around. You may have to bring in the right type of material for the bottom of the ditch if the one that’s already there is not proper.
The pipe present in the trench should not be supported using bricks or other such materials. Such hard objects will cause the poorly supported pipe to bend or break and the joints will eventually fail. The bedding should be properly compacted with hollows made to accommodate the joints in the pipes. A comprehensive support should be used for the whole of the pipe.
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. So that is why a run of drains should be as straight as possible between two points or inspection chambers. An inspection chamber should be present at places where the pipework changes its direction, this is important so that it remains accessible to drain rods and they do not need to go around corners.
If you follow this guidance, drainage and DIY plumbing can be within the range of the most DIY enthusiasts.
