The purpose of an air admittance valve is to provide 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 the 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
Unique technology opens at -0.01 Psi and seals at 0 psi and above
Screening on air inlets to guard the seal
Protective rubber sleeve provides grip for installation and keeps valve free from debris
100% Functionally tested at 1/4 in H20 and 30 in H20 ensuring trouble-free performance
