Learn how drains relate to sewer lines.
The main drain (also known as a sewer line) connects the house with the line for sewers. The pipe is used to transport waste from your home to a municipal wastewater treatment plant. The main drain is connected to the sewer system via the underground pipe, which flows out from the basement and into your yard, generally in the lowest or the tiniest part of your yard. This makes it easier for water to flow to flow both ways: up into the house and then down to the line. This is evident in any simple plumbing diagram.
It is vital to be careful about placing anything in the pipe that can block the flow of water. If this happens the pipe could cause back-ups or, more seriously, cause a blockage to the entire system, and lead to a backup of sewage. The main drain is an enormous pipe which carries wastewater and sewage from your house to a municipal wastewater treatment plant. This pipe is connected to the line for sewers through an underground pipe which runs from your basement through your home, typically along its lowest point or the lowest point of your lawn.
Examine Your Drain Waste and Vent Systems
Drain, waste, and vent (DWV) system is an array of pipes and fittings for transferring sewage away from houses. The system is composed of three parts: drain, waste and vent. DWV systems can be found in all basic house plumbing plans, as well as the ones that are for single-family houses as well as townhouses.
The water pipes that connect your plumbing fixtures to the drain section of the system form a large part of this part. The waste lines capture the waste from your toilets, and take it away to the sewer. Vent pipes allow gas exchange between your house and the outside air and prevent methane accumulation to take place.
The building drain is the lowest spot in the plumbing system. It connects to the sewer lines. It is a part of the drainage system that
