Hi all, I'm sure this is an easy one for most of you. I've got a waste trap similar to the one pictured, but I can't for the life of me work out what size/type of coupling I'm meant to use to connect to the end of the bent pipe (the wider end). I've got 40mm waste pipe going off to the sewer, and wanted to use solvent weld coupling to connect it to the end of that bent pipe. But it's not standard 40mm, nor is it 50mm, so those couplings don't work, the only option I can think of that's left is to use 50mm to 40mm compression.
The actual diameter is about 48mm. I wanted to avoid compression as I don't trust it, but thought it best to ask here as there's probably a proper way of doing it and a reason why it's not a standard size pipe.
Many thanks in advance
