This morning I planned to remove a rad so that I could paper behind it.
The lockshield valve needed an allen key. I turned it clockwise, turned the wooden rimmed thermostatic crown clockwise, and then opened the bleed valve to let the pressure out.
The pressure would not drop. After having let out about 1L of water, I turned the lockshield valve the other way. The water was still pressurised.
I eventually asked the customer to call the plumber that fitted all of the rads the other week. He explained that the thermostatic valves do not shut completely and that I would need to drain down the whole system...
The valves were purchased from Victoria Plumb. I did look at the product description
Are they just rubbish quality?
Over the years I have encountered TRVs that weep slightly, but not ones that won't shut.
