Two of the rads work downstairs...3 don't.
i took the TVR off last night and wondered how pushing the pin down will work as that switches it off. also it is as down as it can go unless i take the plastic nut off and then that reveals the pin. I can't push it down.
the radiators upstairs all work but I have three downstairs that don't.
The pipes leading to the rads are cold.
It doesn't make any difference if i remove the TVR.
I don't know if the pin is up or down to be honest!
I don't want to get pliers and pull it up incase i do any damage...
