[QUOTE="Doc Hudson, post: 416194, member: 1607"] Have you ever put in new inhibitor fluid or sludge remover after removing / reconnecting radiators when decorating? [URL="http://www.screwfix.com/c/heating-plumbing/central-heating-treatments/cat831046#category=cat831046&page_size=100"]http://www.screwfix.com/c/heating-plumbing/central-heating-treatments/cat831046#category=cat831046&page_size=100[/URL] I'd start with drain system down. then refill with a suitable cleaning fluid, run it for a few days opening / closing rad valves to force it around whole system. Don't forget to open up both rad valves including the lock shield ones to let ensure you haven't got a plug of sludge backing up behind a rad valve. Then re-drain to let any loosened muck out. Refill again with suitable dose of inhibitor fluid. go back round re-balance all rads. Doc H [/QUOTE]
