Do not create drainage problems with a badly designed drain system
Drain pipes carry waste effluent from your fixtures down to the sewage system. In sewer systems from houses, pipes are laid in between inspection chambers. The system must be able to clean itself without blockage. Appropriate gradients are used to accomplish this. The system uses mostly UPVC tubing. Its important after laying to sufficiently test before commissioning the system. The tests must be conducted in between the inspection chambers to allow each part of the system to be thoroughly checked.
The laying down of drainpipes should be done in indents in the ground. They can be three to five hundred millimeters in depth. Such sewer systems are enclosed in concrete when they pass below driveways, walkways or under a parking. When commencing the work, excavate to the required levels. The grading must be done near the sewers or the tank. The slope should be in the ratio of one is to four. Proper packing, integrating and cramming of the trench base is usually done to provide a firm foundation. The level in the foot of a trench bottoms should be determined using pegs.
Straight lines must be adopted for laying the drainage pipes as bends will create weaknesses and areas where blockages can occur. Sockets that lead uphill or in the direction of the building must be used for joining the separate pipes. The system should lie on a solid and even ground. In order to connect the female and male sockets, it is necessary to employ a first-rate adhesive which will last. 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.
When the drainage pipes are laid, they must be explored and checked out carefully. Make sure that they are not punctured at any point. Confirm the correct formation of the socket recesses in the foundation. However they should not be too long. The inspection chamber’s entry and exit points need to be graded well, in addition to being leveled. After completing all joints cover the system with soil. Connect to the sewer or septic tank. And the final step is to link the system to the utilities to finish the drainage system and commence the final test.
