Title: Air Admittance Valves
Post by: Fordy on July 28, 2016, 04:35:57 PM: What is it with all these air admittance valves we are seeing - even on brand new homes? We have been called out to a number of them out east Auckland with the toilet not draining correctly - always installed the same way...just plain lazy or untrained....maybe I should post this in the rant/rave section ;D ;D

I gather that there was no terminal vent on the drainage system at all.
What other horrors lurk boggles the mind.
What muppet signed this off i wonder.... what certifyer bears the responsibility...

Yep - no main TV on any of that - the 40/50mm air admittance valve is it.
