This air admittance valve is engineered to open at -0.01 Psi and seal at 0 psi and above, ensuring it closes by gravity to seal the vent terminal under positive internal pressures. It features a protective rubber sleeve for easy installation and to keep the valve free from debris, and is 100% functionally tested to ensure trouble-free performance.\u003c\/p\u003e\n\u003cp\u003eConstructed from durable PVC material, this valve complies with ASSE 1050, ASSE 1051, ASSE 1051-2009, and NSF 14 standards, and is IAPMO listed for added assurance.
