Hi there
Our 3 bed house had an issue with a diverter valve 3 weeks ago and since getting it replaced 4 of the 5 downstairs radiators are not heating up (2 get a tiny amount of heat, 2 not at all). Upstairs radiators are fine, and the 1 downstairs nearest the boiler is fine too. Pressure is around 2, all radiators bled, and the pump is turned up to 3 and definitely turning.
Today a friend and I even took off all 4 of the non-working radiators and blasted out an impressive amount of sludge using a hose pipe. Gutted to say even this didn't help.
Oddest thing is that the white pipes leading from the walls to the radiator are getting hot on most of the radiators, so no idea why the hot water isn't getting in (they are all open on both sides...).
I'm pretty much at the end of my tether (thanks mainly to the wife's moaning...) so any suggestions would be brilliant. I've spent most of the last week reading this forum but can't find a problem quite like this one. It's a good puzzle at least....
