Durgo / Air Valve - Can I Use The Small Type For A Toilet ?
Discussion
I have used the std 4" durgo for toilets in the past but have just found out that there are smaller versions that fit to 40mm pipe.
Will these let enough air through for a toilet or are they only for sinks ?
(I'd want to plumbing it to the sink which is connected to the toilet)
All my bathrooms have their own run to the inspection chamber so they are effectively all at the end of the run - so will durgos be acceptable ?
It is a private sewer to my septic tank if that matters.
