In our bathroom we have a 40mm bath waste pipe at skirting height and a 32mm basin waste pipe approx 2' above this.
The bath waste is approx 3m in length and the basin waste approx 2m. Both go into a vented stack.
My question is, can i remove the separate basin waste and tap it directly (vertical under the basin) into the bath waste. Or are there any regulations that prevent this?
If this is possible i presume it would also be advisable to fit an anti syphon on the basin trap.
