any idea how to connect the bath (which on the right hand side of the attached pic) with the basin (in the middle) to the toilet which will be to the left. my idea to run 40mm pipe from the bath and T Junction the basin to it (with 32 to 40 reducer) then boos it to the brown (the toilet 4" pipe), however, this pipe will be cut to the ground and the pan connecter will be fitted into it. Can I boss to the pan connector?
