Repair Broken Sewer Pipe Chino CA
Dave used acoustic water leak detection equipment to locate the position of the leak. He then removed the broken section and replaced it.
These sewer line vents are there to prevent sewer gases from getting back into the home, instead venting them usually through the roof.
As water flows through the pipe, the air between the trap and the main sewer line cannot escape and is pushed ahead of the water flowing down the drain line. This creates a vacuum. The sewer vent is there to get rid of this vacuum air bubble.
