Air admittance valve

trevormuk · 18 Sep 2004

Is there a minimum height the valve should be from the point where the pipe from the toilet enters the soil pipe?

My existing bathroom has a vent pipe 600mm inside a boxed wall...

Many thanks.

Cheers

The air admittance valve needds to be higher than any thing else attached to the soil pipe. Foe instance, if you have a hand basin also attached to the soil pipe, the valve needs to be higher than the overflow of the hand basin.

Hope this makes sense
