110mm Push-Fit Air Admittance Valve

A push-fit air admittance valve for 110mm soil stacks. It opens to let air in when the stack is under negative pressure, protecting trap seals, and closes to keep drain smells out.

Typical uses

Terminating a soil stack inside the building, in a roof space or boxing. Check Building Regulations: at least one open vent is normally required on a drainage system.
