Description
This Air Admittance Valve (AAV) provides essential ventilation for soil and waste pipe systems, allowing air to enter the pipework when water flows while preventing foul odours from escaping. Designed to maintain trap seals and ensure smooth drainage performance, the valve is quick to install and ideal for use where external venting is not practical.
Key Features
✔ Automatic One-Way Venting
Opens under negative pressure to admit air into the system, then closes tightly to stop odours from escaping.
✔ Prevents Trap Siphonage
Maintains correct pressure within the waste system to protect water seals and prevent gurgling or slow drainage.
✔ Compact, Low-Maintenance Design
Fits neatly indoors within bathrooms, kitchens, utility rooms or boxed-in pipework.
✔ Reliable, Durable Construction
Manufactured from high-quality, impact-resistant plastic for long service life.
✔ Push-Fit / Solvent-Weld Compatibility (depends on model)
Available in multiple connection types to suit most 32mm, 40mm, 50mm or 110mm waste and soil pipes.
