Hi all
I found the cause of one of my radiators being cold. It is 5-year-old 15mm British Gas TRV' plastic head. When I took the plastic head off, when the system was working, to check for stuck pin, the radiator suddenly started heating up properly. When I put the TRV's top back - it stopped, even on the highest setting. It looks like the inside movable part is not moving up and down.
Does anyone know of any compatible TRV's heads I can buy from plumbing merchants to replace the BG' TRV's head so I don't replace the whole thing?
Many thanks for your help
