PVC Adapter is designed to terminate individual, common, circuit, loop, island fixture, vent stack, or stack vents, preventing siphonage of fixture traps. This valve allows air to enter the plumbing drainage system without extending a vent to open air, effectively sealing against sewer gases. Its unique technology ensures it opens at -0.01 Psi and seals at 0 psi and above, making it reliable under various pressure conditions. The valve includes screening on air inlets to protect the seal and a protective rubber sleeve for easy installation and debris protection.\u003c\/p\u003e\n\u003cp\u003eManufactured in the USA, this air admittance valve is 100% functionally tested at 1\/4 in H20 and 30 in H20, ensuring consistent performance. It comes with a lifetime limited warranty and complies with ASSE 1050, ASSE 1051, and ASSE 1051-2009 standards, as well as ASTM D-2661 and ASTM D-2665.
