Hi guys, I would appreciate an advice - I changed a thermo valve on a radiator a couple of weeks ago, and it was working fine. But the customer called me a week later and said that the radiator starting making loud banging or screeching noises every time about an hour after the central heating was switched off at night. When I came to see it yesterday the heating was off, so I could not see or hear anything, and could not do anything. The customer said he checked it on internet and recons it must be due the new valve. I said I would consult the forum and get back to him. Your help be much appreciated.
