Air Admittance Valves & Parts

The negative air pressure in the drainage system is taken care of by these uniquely designed air admittance valves, and this usually happens when the fixture is drained. These are one-way vents installed after the trap on the drain line of installation. When there is negative pressure in the drainage system, the air admittance valve with the sealing mechanism lifts to let the air into the system. It is essential to install the valve in the area that is easily accessible and has free airflow.

Now you do not need expensive roof penetration and vent piping to give ventilation that prevents loss of water seals in traps by using the STUDOR PVC Air Admittance Valve Adapter. It features a vermin protection system that ensures the rodents and insects do not enter the valve. The product is used for residential as well as commercial purposes due to its compact design and easy installation.
