Do not create drain problems with a badly designed drain system
The purpose of drainage pipes is to expel the discharge coming out from the home and direct it into the septic or sewer tanks. In the case of the home sewer system, pipes are placed in between the inspection chambers. This drainage setup must be self-cleaning, with running wastewater doing the flushing. A proper slope is required to ensure this smooth flow. Normally UPVC pipework is employed in the sewer system. However testing is very important before the system can start functioning. This should be done between the inspection chambers.
The laying down of drainpipes should be done in indents in the ground. They can be three to five hundred millimeters in depth. When the system passes below a parking, walkways or driveways, it is encased in concrete. Excavation of the channel to the desired level must be done at the time of work commencement. These must be inclined towards the sewers or effluent storage tanks. The slope should be in the ratio of one is to four. The bottoms of the trenches are usually highly compressed. To fix the levels in these bottoms, one can use pegs.
Maintaining straight lines is essential while laying down the drainage pipes. This should be joined with sockets leading uphill or towards the building. The ground containing the system should be compacted and consistent. Male and female sockets should be used to join the pipes using a good adhesive. The adhesive pack comes with instructions, make sure they are strictly followed. When connecting to the inspection chambers, the pipe should go into the full wall thickness. Clean any debris from the pipes.
The drainage pipes are carefully examined when laying. This is important to make sure that there is no leakage. All socket recesses have to be adequately formed in the foundation. The hooks must be as stunted and small as possible. The entry and exit points in an inspection chamber should be level and well graded. After completing all joints cover the system with soil. Connection is then made between the system and the septic tank or sewer. Complete the drainage system by connecting the utilities and test the full system.
