Common Questions

How do air admittance valves work? When water flows down the pipe, the valve opens to let air in so traps aren’t siphoned dry. When the flow stops it closes again to keep drain smells in.

What size air admittance valve do I need? The Ventapipe 50 suits 3 inch (75mm) or 4 inch (110mm) soil pipe with its dual fit seal, and it also has a 2 inch outlet. Check your pipe size before buying.

How do you fit an air admittance valve? Fit it upright on the pipe it’s venting, pushing it on fully so the seal grips. It should sit above the flood level of the appliances it serves.

Can air admittance valves be boxed in? They can, but the valve needs air to reach it. Leave a vent or grille in the boxing so it can breathe.

Can I use an air admittance valve instead of a vent pipe? On many branches and stacks, yes, but a drainage system usually needs at least one open vent to outside. If in doubt, check with building control.

What is the air flow of the Ventapipe 50? It’s rated A1 with an air flow capacity of 16.3 l/s. The maker code is VP50-100.
