I know this has kind of been done to death as part of a system flush as this is all i find googling the web but i'd like some advice/opinion on what good methods there are for flushing an individual radiator.
Just some background:
I've flushed my system and after reintroducing the water supply bled all of my radiators in turn. One radiator however hissed out some air as per normal then went quiet. I waited a while the removed the bleed nipple until it came out of the radiator. Still nothing. The rad warmed slightly up to about a quarter of the way up and stayed cold the rest of the way. I had thought that this rad had a problem with the trv before but now i'm convinced there's a blockage. Oh yeah, I replaced the bleed nipple BTW.
