Plumbing Drain-Waste-Vent systems, known as DWVs, consist of drainpipes that provide a network for the removal of waste, as well as vent pipes that prevent unwanted gas from escaping inside the building. Vent pipes also maintain the necessary balance of pressure to allow water to flow. In a simplified example, water in an inverted bottle without an air hole will glug and gasp when emptied. Adding an opening to the bottom of the bottle will turn the process into an efficient, steady flow because the bottle “breathes.” This is what an AAV can do.

1/4-Turn Water Stop Valves provide easy on/off operation for controlling the flow of water and are designed for connections where a water line passes through a wall. Whether replacing or installing new, it is crucial to properly install and maintain your Stop/Shut off Valves.

Before you begin, make sure you choose the correct shut off valve. Don’t know how to choose? Check out our Oatey Stop Valves Overview video and jump to 0:32.
