Rated 4 out of 5Â by PAYaProfessional Air admittance valve
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.

Rated 4 out of 5Â by dangerfieldm Appears to do what is needed.
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.

Simple little device that converts easily from 32mm, to 40mm, to 50mm.
Ideal for lofts and other small dark places!
