Rated 4 out of 5Â by frenchman air admittance valve
good quality item and easy to fit as it is a mulit-size fitting. Solves vacuum problems in pipework.

Perfectly good air admittance valve. Neat little multi adapter that allows you to solvent weld the AAV to 32,40 or 50mm pipe. More expensive than a piece of plastic that is churned out in there millions should cost.

A really good AAV that can be fitted below the overflow level of the highest appliance which is usually the wash basin. Comes boxed and looks and performs like real quality.

Needed to aid flow from shower tray, and seems to do the job most of the time. Too early to say yet whether performance is as expected.
