Vent Toilet With Air Admittance Valve

Keep in mind that you need to install air admittance valve at least 4 inches 10 cm higher than a drain line.

Vent toilet with air admittance valve.

World leading air admittance valves. The negative pressure activated one way vents to protect the trap seals in the drainage system by allowing the intake of air so that the right level of pressure within the drainage system is maintained. More product details close. Depending on the valve and the size of the vent aavs can support one or multiple vent lines.
