Vent an Island Sink...and Other Tricky Spots

A handy one-way valve eliminates most of the plumbing work

Putting a sink in a kitchen island used to mean that you had to run a complicated plumbing vent loop up, down, and under the floor until you reached a wall where you could extend the vent line through the roof. Enter the air admittance valve (AAV). This handy gadget is a one-way valve that allows air to enter when the sink is drained but keeps sewer gases trapped in the vent line. Lynn Underwood, a building official in Norfolk, Virginia, gives the pros and cons of AAVs. You'll learn where you can use them, how to install them, and how to convince your building inspector if (s)he's dubious.
