Plumbing TermDrain-Waste-Vent (DWV)
/drain-waste-vent/
The pipe system that removes wastewater and vents sewer gases from your home.
Full Definition
The complete system of pipes that removes wastewater from fixtures, carries it to the sewer, and vents sewer gases safely outside your home.
Common Usage
“When plumbers discuss your home's DWV system, they're referring to all the drain pipes, waste lines, and vent stacks working together.”
Did You Know?
The vent portion of your DWV system is just as important as the drains - without proper venting, drains would gurgle, flow slowly, and sewer gases could enter your home through dry traps.
