When going to remove a radiator, so we can decorate our hallway, I noticed that the TRV was wobbly - so that the joint between the TRV and the vertical pipe into it was moving, even though the nut was fully tightened. Also noticed it is prone to leaking a bit. On the other radiators in the house, the TRVs seem to be joined solidly to the pipe and don't move.
With some trepidation I have managed to drain the system and taken the TRV off. I noticed that the olive doesn't go very far down the pipe, just stays flush with the top. I wondered if the problem is that not enough of the pipe is going up into the TRV, making the joint not very strong?
The olive does come off the pipe, but I can't get it to slide down any further. I wondered about lightly sanding the lower bit of the pipe to see if I can get it to slip down more. But I don't know if this is the right approach at all. How far should an olive go down the pipe? Is exactly flush with the top OK? How do I get a better join?
Right now the join leaks as soon as I put any pressure in the system. Hence I can't use the combi boiler for hot water either... I am loath to call out a plumber for this. Even though I don't know what I'm doing, it seems like I should be able to fix it... help!
