I want to temporarily remove a radiator as I'm redecorating. I plan to repaint the radiator and I really need to remove the skirting behind it. And repaint the wall behind it. Anyway, never min why I want to do it...
The radiator has a TRV. If I remove the TRV and fit a decorators cap, or if I shut off the TRV, the radiator does not get hot. So I conclude that that end is properly shut off. Although I've closed the lockshield valve (?) at the other end, the radiator is still pressurised and when I try to remove the radiator water floods out. Do those valves fail open? Is there any alternative to draining down and replacing the valve?
