I re-plumbed our radiators today. I used some new copper pipe on some and re-did the compression fittings with new olives etc.
I thought I did them perfect, plenty of PTFE tape, but when I refilled the system I found two leaks, both in the same spot on different radiators.
They were weeping ever so slightly from the bottom of compression nut that compresses the olive. So drips would runs down the pipe.
I redid the fittings 3 times, tried a different nut but one still leaks slightly. I really don't know what I did wrong.
Should I be using some sealer around the compression olive? It doesn't make sense to me that the ptfe tap is faulty as surely it would be leaking from the top of the nut, not the bottom.
