24 DFU Capacity Air Admittance Valve's one-way valve allows air to enter the plumbing drainage system when negative pressures develop in the piping system.
Provides a method of allowing air to enter the plumbing drainage system without the use of a vent extended to open air and to prevent sewer gases from escaping into a building.
An air admittance valve is a one way valve designed to allow air to enter the plumbing drainage system when negative pressures develop in the piping system.
The device shall close by gravity and seal the vent terminal at zero differential pressure (no flow conditions) and under positive internal pressures. For use as a secondary vent.
One size approved to handle up to 1.5 in. – 2 in vent pipe. Opens/closes as needed by building's plumbing system. The highest quality technical and customer support programs in the industry.
