Air admittance valves

Air admittance valves (AAV) are used to ventilate soil or waste pipes so the wastewater drains suitably from the property. They’re designed to allow air to enter the drainage system to balance the pressure and prevent siphonage of the water trap when negative pressure develops in the system. Tradepoint offer a choice of push fit or solvent weld jointing systems.
