All About Your Sewer System
When you turn the faucet off and the water flows down the drain in your sink or you flush the toilet, the waste needs to go somewhere and the pipes that carry these liquids and solids away from you home are called the drain, waste or drain waste vent (DWV) system.
To make sure waste gets to where it’s supposed to go, this system is equipped with a range of pipes with large diameters. The system has three important components. As the name implies, the drain lines carry the water away from the showers, tubs and sinks. The waste line takes care of what needs to leave your home from the toilets and the sewer gases are vented through the aptly named vent lines. These lines also provide air pressure so waste water can flow freely.
