I have recently plumbed in a new upstairs bathroom. Where the soil pipe
exists the building the female socket of the branch butts up against the
wall. This means the vertical soil pipeis too far away from the wall for the
support clips. Should I increase the size of the hole in the wall to
accommodate the additional diameter of the branch or use some angled bends
to bring the vertical pipework closer to the wall so I can clip them in
place. Any other solutions would be appreciated.
When I did this, the local building control officer was very helpful and
told me precisely how I should do it, so that he would sign it off.
Burying joints in the wall doesn't seem to be a good idea. Differential
expansion could cause the joint to leak...
You may have to put a dogleg in the vertical pipe, so there is enough
room to bring the wall pipe clear of the wall and then turn it towards
and into the branch.
But it will be the bco who has to approve the thing, so you may as well
