Hi,
We’re converting an old store/workshop joined to our house and installing a small shower room with the wastes connecting to the old clay pipe in the floor where the original toilet once was.
We needed to bring the floor up 100mm for insulation and had a plumber set the new waste pipes for the basin and shower within this and connect to the clay pipe before we put the floor boards down.
Building control say we need to install a durgo valve and the plumber has not currently allowed for one on the run.
I’m wondering if we need one at the end of the run (sink), where everything joins the stack, or both...
My main issue is that the 110mm stack is positioned quite far forward away from the wall in the floor (220mm) so I’m already trying to use a space saving pan connector which will not allow a boss. If I can ‘get away’ with just the AAV at the sink end then that’s great, but I don’t want any problems further down the line.
