Hi,
I've just installed a few radiators and I have 10mm mini bore going to 15mm TRV's and lockshields. I used 15mm to 10mm internal reducers on the valves with copper 10mm olives, but most of my joints are leaking. I even wrapped the olives in PTFE before tightening the fitting. Looking at the design of these things, I'm wondering what stops the brass fitting that goes into the valve from leaking?
Should I undo and apply loads more PTFE around the olive or some liquid PTFE to around the olive this time?
Thanks in advance.
