110mm Internal Air Admittance Valve
An Air Admittance Valve is an ingenious device that allows a soil stack to terminate inside a building. AV110 Internal air admittance valves are installed onto the soil pipe using a solvent weld joint.
All of our Air Admittance Valves are Kitemarked and conform to BS12380:2002.
The one-way valve opens to allow air in to the soil system when required to balance negative pressure, but without allowing any foul air to escape. The valve must be fitted at least 200mm above the highest "wet point" in the soil stack, i.e. the highest point in the system that water can reach. Valves can be left on show or hidden within a duct, cupboard or loft space.
