Mcalpine VP100E INTERNAL/EXTERNAL AIR Admittance Valve 110mm 61020038

This air admittance valve is designed for use with 110mm soil pipe systems, providing a solution for both internal and external soil stacks. The valve allows air to enter the pipework during negative pressure events, reducing the chance of water seals being lost from traps in the system.

It is commonly installed where venting through an external stack is not possible or practical, such as in refurbishment projects or internal soil stacks. The straightforward push-fit design means it can be quickly fitted onto standard pipework, helping to maintain effective air flow and limit the risk of odours entering occupied spaces.
