Drain, waste and ventilation. Or DWV

Have you ever heard the term DWV?  In the plumbing world it stands for drain, waste and vent.  In your home or property the outlet at the bottom of any plumbing fixture enters the drain system of your home.  Once entered, it is considered waste water and enters your municipality's sewer system.  The pipe that proceeds above any plumbing fixtures and exits the roof is considered a vent.  Much like opeing a container on both ends, the vent system enables a better flow of your DWV system and releases sewer gas into the atmosphere.  DWV
