This grey 110mm air admittance valve is designed for use in soil systems where venting is required without an external stack. The unit fits directly onto 110mm waste or soil pipe and helps to regulate air pressure within the plumbing system.
Commonly used in residential and commercial installations, the air admittance valve is suitable for stack or branch connections. It assists in preventing traps from losing water and helps minimise odours on site by allowing air into the system while blocking foul gases from escaping.
