The FloPlast Air Admittance Valve (AV32) is a white compression valve designed for use with 32mm waste pipes. It allows air to enter the pipe system while preventing sewer gases from escaping into the property. This valve ensures proper ventilation and helps maintain a healthy indoor environment by preventing unpleasant odors from entering homes or buildings. Features: - Made of high-quality materials for durability and reliability. - Easy installation process without the need for additional fittings or adapters. - Suitable for use with various types of waste pipes, including universal waste pipes. - Designed to meet specific safety and performance standards for optimal functionality. Benefits: - Ensures proper ventilation within the pipe system, reducing the risk of vacuum build-up that could cause blockages. - Prevents sewer gases from entering the building through the pipe system, maintaining a healthier indoor environment. - Simple installation process saves time and effort compared to other valve options. - Durable construction ensures long-term reliability and reduces maintenance costs. Air admittance valves in waste systems are used to prevent trap seals from being lost because of siphonage an issue that is often indicated by drain odours in the room and a gurgling sound when any water is drained from the sink or basin. Because of this they are usually a retro-fit item. Air admittance valves are sometimes referred to as Durgo valves. They are cleverly engineered fittings that allow air to be drawn into the pipework to prevent siphonage when pressure builds up in the waste pipe, but crucially no foul odours can escape from the system. The valve is connected to the waste pipe using the integral compression coupling on the tail. This valve can be connected to most 32mm plastic waste systems and some copper waste pipes. It is usually installed in a waste tee that is cut into the main waste pipe run. It is manufactured to BS EN 12380:2002
