HI,
I've got a thermostatic radiator valve with a 10mm pipe going into it. It's leaking slowly at this junction.
I invested in some nice new 10mm olives, but on draining the system down and attempting to replace it, I discovered that the valve is a standard
15mm fitting with a conical insert fitted to reduce the diameter, and a corresponding hat-shaped ring around the pipe. I cleaned the corrosion off the surfaces, applied PTFE tape and did it back up, which seems to have improved things somewhat, but not cured the leak entirely.Presumably the hat-shaped bit functions like an olive, and I need to fit a whole new reducing thingy?
(Ideally, I'd rip the lot out and fit proper pipes, or at least fit a new TRV, but that's the domain of the landlord. I was hoping for something I could do quickly and easily myself that didn't mean hanging around all day waiting for contractors to not turn up.)
Kim.
