I live in the UK and here’s my problem. I have a compression joint connecting a 22mm copper pipe to an old 3/4 inch copper pipe. I’ve used an imperial olive on the old pipe side but it still leaks even after retrying a couple of times with new olives. I’ve tried wrapping PTFE tape around the olives but no luck with that either. Any advice?
The problem is made even more infuriating by the fact that the pipe is between another pipe and the wall thus restricting access with various spanners/wrenchs. Any advice?
