I have a house with an old central heating system but new boiler. I have removed one of the radiators to decorate, the radiator has an old trv which connects using a 3/4” tail. When I came to connect it all back up there were leaks from the inlet copper pipe to trv body connection. On closer inspection the olive was mangled. I removed the olive but then struggled to get another on because the pipe was linked and bulging. I cut the piece closer to the floor and went to join the pipes to find out the pipes are imperial. A quick run to screwfix for a 1/2” to 15mm coupler. Ready to go.
But here is the issue. The connector for the bottom of the trv body has a compression joint, but the nut is male not female, there is no chamfer on it for the olive, and it doesn’t allow the olive to move down the pipe. When I tighten the olive it never fully tightens as the olive as overhangs the end of the copper pipe.
Am I missing something really obvious, but it doesn’t seem like a standard olive is the correct sealer. What do I need?
