Air Admittance Valves

Air admittance valves, also called cheater valves or mechanical vents are mechanical devices that take the place of plumbing vents. Structure Tech, your Minnesota home inspection company puts air admittance valves to the test in this video. Air admittance valves are inexpensive, they work, they can reduce the number of plumbing vent penetrations at the roof, they won't get blocked by frost, they're listed and approved by several listing agencies, and they cost way less to install than a plumbing vent.

Oh, and they're not legal here in Minnesota.
