FloPlast AF32W Air Admittance Valve is rated 4.5 out of 5 by 13.
Rated 5 out of 5 by from Used on Soil Stack I was having issues with the normal 100mm values as not admitting enough air fast enough, hence was getting air pulling thought other traps.. ran one of these bad boys in 40mm with a 100mm to 40mm reducer to the stack. The reduction in pipe diameter created an increase in air flow thought the 40mm pipe to this value.. problem solved.

Rated 5 out of 5 by from Perfect This is a perfect little AAV that fits three pipe sizes. Easy to install, well-made, and runs silently. This is my second one. One vents a washing machine, the other a sink. Both are flawless.

Rated 4 out of 5 by from Good quality valve A well designed and manufactured valve which can be fitted to any of the three pipe sizes quoted. It is made from good quality plastic which is not brittle. Air admittance appears to be good and the valve has worked well where it has been used. Time will tell as to long term reliability.

Rated 4 out of 5 by from Not for use with Saniflo !! Beware - DO NOT use for Saniflo in the outlet pipe. FloPlast tech support confirm these valves have inadequate positive pressure capability - they will (mine did!) blow liquid through the top of the valve - nice shower feature! Saniflo recommend and have tested the MultiKwik/Hunter Plastics WW150 - can confirm it works fine. Note the WW150 has the same "air tightness test pressure 10Kpa" spec as the FloPlast - so you'd think they were equally good, No! It's the max positive pressure that matters (not actually written on the box). Used with Saniflos an AAV must handle a min of 10PSI (69Kpa). WW150 is good to 15PSI apparently, and also has a replaceable valve mechanism. Can't comment on non-Saniflo use.
