OK, so I have pretty much finished installing a new bathroom. It has been a lot of work but hopefully worth it.
Now, I have been having problems with compression joints. I read that you should wind PTFE on the thread, put on the olive and nut, push the pipe in then do it up finger tight. Then give it a half turn with a spanner and it should be done.
I followed that advice and they ALL leaked. So I went around with a pair of adjustable spanners and just did the bu**ers up tight. And I mean tight. Looking down a pipe that I later replaced I can see that the olive is clamping down on the copper and "necking" the pipe.
Is this bad? I don't want the joints to fail or leak later on. In fact I am tempted to remove all the new pipework I did and redo it all with plastic pipe and push fittings. I know o-rings don't last forever, but I am beginning to think they have better odds than my plumbing!
