Air Admittance Valve 110mm Black

Aquaflow’s 110 mm air admittance valve is necessary for the prevention of waste liquid expulsion and the build-up of bad odours. When a toilet is flushed or you draw water from a sink, pressure is built up that needs to be released – an admittance valve does this.
Designed for indoor use, this air admittance valve will draw fresh air in from the outside while preventing foul air from the plumbing system from being released into domestic spaces. You’ll find that installation couldn’t be easier – simply push it onto the top of a soil pipe, weld with sealant, and the job’s done. The domed top means there’s no risk of condensation pooling on the admittance valve and affecting the intake of fresh air.
The chassis is made of lightweight, durable PVCu that’s completely waterproof and corrosion-resistant. This admittance valve is in accordance with BS EN 12380:2002 and 91.140.80, the industry standards for air valve and drainage fixtures.
• Solvent weld
• Designed for internal use
