I have one cold radiator in my house, I have already fixed a few by lubricating the pins on the TRV and that worked a treat but this last one is giving me hassle. The pin goes in and out when I use pliers (gently of course) but when it goes down it doesn't come back up automatically, its too stiff. (It has a westherm thermostat if that is relevant). Anyway, so I've just bought a new radiator valve (a lockshield one, I don't care about the thermostat - I just want a working radiator!). But before I start draining the system and so on, i was wondering if there were some tests I could do to make sure it IS the trv which is the problem, the last thing i want is to go through all the palava of changing it only to find it STILL doesn't work!
If the pin is UP, even if the thermostat isn't attached, should the radiator still heat up? If it doesn't, does this mean it isn't the TRV?
Thank you!!
