An amateur here trying to build a complete bathroom from scratch. I somewhat foolishly bought my bathroom suite from Victorian Plumbing...yes, I've already read the forums about plumbers cursing their 38mm waste pipes!
So, my problem is...I have a 38mm (OD) metal waste pipe!
I want to install a roll top bath and take the metal waste pipe to one side and out through the skirting board to a 40mm solvent weld pipe.
I need a fitting that's compression one side to take the 38mm pipe and 40mm solvent the other. I don't want a compression/push fitting within the wall, if I can help it. If there are any future joint problems I want to be able to access it. eg. the compression fitting outside of the skirting board. I'll happily machine down one of those plastic compression rings to fit under a chrome cover ring, if need be.
I have looked absolutely everywhere and have not found a suitable fitting. I have a lathe and am even considering making something up myself!
Please help with ideas...I'm getting desperate now! I'll even buy you a beer (post lock down!)
