Hi all
Thanks for the various feedback. When I wrote AAV I did mean Air Admittance Valve i.e. the generic name for the Durgo. Sorry for any confusion.
Whilst putting the Durgo/AAV in would give a slight space advantage and improve look of the bathroom (as it would mean sink is not tight to the side wall) my inclination is to retain vented stack. Mainly this is "gut feel" ie one less part to fail and based on various web articles / blogs etc where people have had problems.
I am sure 95% of the time they work perfectly, however if they don't the consequences are pretty unpleasant.
Regards Iain
