Hi there,

Any experiences with air admittance valves?

I'm refurbishing my bathroom.
At the moment the stack pipe takes air from the outside (the roof), and
this means that I have a column in a corner of my bathroom.
To save space, and why not to improve insulation, I would like to cut
my stack pipe halfway (say at basin overflow level) and close it with
an air admittance valve on top.
What do you think?

Also, what's the position of building control about this? Is this stuff
regulated?
I'll ask them tomorrow, but BC in my council tends to answer very
randomly. So I guess if I get an answer I don't like I'll try again

Cheers,
Julian

everything's regulated these days... side effect of a Labour government I'm
afraid. i cant see much of a problem with it...afaik, as long as your house
has another stench pipe, you can use air admittance valves. why at basin
level? if i were you id cut as low as poss without interfering with flow
etc.
