Hi, I'm new here.

We're redoing our bathroom and would like to join toilet waste on one side of a branch, and a conjoined bath and basin on the other side. The regs say this is iffy with a non-swept junction.

Would a swept junction like this work if we put a 50mm to 110m offset adapter like this on one side, with the offset making the 50mm entry higher than the centre line?

Is there a reason that’s stopping you doing it properly?

Building regulations document H would be a good starting point.
I've already had a read through of the crossflow section and thought my solution complied. Your responses have made me reconsider my understanding. I'll reread it when I have more time and respond.
  • Thanks
