Soil stack replacement Q
On Mon, 29 Jun 2009 04:51:44 -0700 (PDT), a certain chimpanzee, Jethro
randomly hit a keyboard and produced:
our bungalow ("L"-shaped) has a nuisance soil stack (stench pipe)
situated in the back, in the inside corner of the "L". Currently it's
made of cast iron, looks grotty,and is a pain, as the guttering is
squeezed behind the angle where it goes up.
I know it's possible to replace it with a straight pipe, which enters
the eaves, and vents through a chimmney in the roof (replacing a
tile).
However, since the purpose of the pipe is to admit air (to prevent
siphonage), is it possible to fit a new shorter pipe, with an air-
admittance only valve ? I'm sure I've seen one advertised ...
You can't mount it externally.
