Hi,
The radiator in my girlfriends bathroom is cold and has been for a while now, maybe 12 months!. She has a combi boiler and TRV's on all radiators. Took the the head off the trv on the cold rad and tried to free up the valve but to no avail. My next thing to do is to turn off all the other rads and try and force the blockage through but if this doesnt work i think i may need to flush the system. Whats the best way to flush a pressurised system?
