I am fitting a bathroom and I'm a bit stuck on the waste pipes-
I have a bath waste joined to a basin waste with 50mm pipe which goes to the soil pipe-
The shower has 40mm pipe that goes through the joists and then changes to 50mm once out of the joists and tees into the bath and basin 50mm pipe- I guess the water from the bath would come out of the shower without a non return valve, ( Like this one ) which is just before the tee to the soil stack. I am limited by the height of the joists which is only 145mm..
here is a drawing-
any help greatly appreciated.
