I've cut the pipes square, cleaned them with wire wool, applied silicone jointing compound under over and around the olive. The I've hand tightened and finally finished off with a spanner.
Despite all of this, they still have very tiny leaks - so small that you just get the occasional dab on a tissue. The problem is the joint is on the pipe work to a radiator on a pressurised system that I'm going to bury under a ceramic floor. I would ignore it but it'll always be there in the back of my mind!!
So what's the solution? Do copper olives help? Will dismantling and applying some PTFE tape around the joint make it water tight?
HELP!
By the way, are Cuprofit pushfit copper fittings any good? I'm tempted to use one of those instead?
