This air admittance valve is manufactured for use with 4 inch (110mm) soil pipe systems, featuring a solvent weld outlet for a secure connection. It is typically installed on vertical soil stacks where a traditional vent to atmosphere is not practical.
The unit allows air to enter the system while helping to prevent odours from escaping into occupied spaces. Suitable for both new builds and retrofit applications, it provides a straightforward solution for pressure equalisation in waste and soil installations.
