In this video we walk through the installation of a OATEY Sure-Vent 1-1/2 in. x 2 in. PVC Air Admittance Valve. The Sure-Vent features a 1-way valve that permits air to enter when negative pressures develop in the piping system. The Sure-Vent closes by gravity to seal the vent terminal at zero differential pressure. The Sure-Vent prevents sewer gases from escaping into your home!
