Air Admittance Valves

Air Admittance Valves (AAV’s) allow air to freely enter the sanitary pipe work system and prevents the escape of foul gases into the building. They are suitable for 32-110mm waste and soil pipes. The 32mm, 40mm and 50mm AAV provides a universal connector for waste pipes, and the 82mm to 110mm air admittance valves are ideal for soil pipe systems. When installed into sanitary pipe work systems, air admittance valves will prevent the loss of water from trap seals due to induced siphonage. Each product is manufactured from high gloss white plastic that provides a modern, clean aesthetic look. Every product is individually tested and numbered prior to dispatch thereby ensuring that the end user can install the product with added assurance and confidence.
