The Drain System | Best Pick Reports

The drains and sewers that send wastewater away from your home work solely through gravity and so may clog from time to time. Sewer lines are also susceptible to damage caused by corrosion, shifting soil, and tree roots. In these cases, the help of a sewer and drain specialist is necessary.

Sinks, toilets, and other household plumbing fixtures each have a drain. Every fixture drain is connected by a branch drain line to the main waste and vent stack, which in turn leads to the main sewer line, usually located near the lowest point of the house. Throughout this system, vent pipes also lead to the main waste and vent stack, which is vented at the roof; venting allows sewer gases to escape and regulates air pressure in order to keep fluids flowing smoothly.
