Drain-Waste-Vent System

Though it isn’t one of the most glamorous parts of a house, the排水废气(DWV) systemis one of the most crucial. The job of the drain-waste part of the system is to carry waste water and sewage from sinks, bathtubs, showers, toilets, and water-using appliances such as dishwashers and washing machines and deliver those wastes to the septic tank or public sewer.

The vent system—part of the plumbing that is usually less well known to most homeowners—is connected to the drain-waste piping, and its job is to ventilate sewage gases so they don’t build up in the house. The vent system also helps drainpipes maintain the right pressure for proper drainage.

DWV系统的管道通常在视线之外,隐藏在墙壁,地板下方,在阁楼。但是当系统不再正常工作时,它几乎不知情。堵塞的排水管是DWV系统中发生的最常见问题之一。

Water supply plumbing delivers hot and cold water to the sinks, tub, toilet, and shower. This system originates at the municipal supply or other fresh water source, goes through the meter, and is delivered to the house. At the water heater, it splits into two lines—one that carries cold water and the other that delivers hot water from the water heater to the fixtures that require it.

The drain-waste-vent system collects waste water from fixtures and waste from toilets and delivers them to the sewer or septic system. Near each of the sinks, tubs, showers, and toilets, vent pipes exhaust sewer gases up and out the roof and provide air pressure so wastes can flow freely.
