1 Radiator not working.......

[Harvest Fields]

Yes mate but do them one at a time.

Close both valves all the way and open them
Back up again. Remember to count how many turns you have done

Hi again, they are about equal 4 turns..

Close them both, then open them all the way then adjust them back to where they was mate.

Hi, nothing but thanks. I think I need to remove the radiator & see if we have any flow to it at all ...can't work it out

Hi again, I have no flow to the radiator only a trickle coming out,

Sounds like a blockage in the pipework then.

Best way to clear this? If I fix a hose to the flow inlet should this do the trick.

1. In your post #15, was this with the radiator and both valves removed? In other words, with the ends of both flow and return pipes completely open was there little or no flow?
2. You need to establish which pipe (flow or return, or both) is blocked.
3. It would be better to flush through from the other end of the offending pipe(s), for example, from the next radiator preceding / following this one, flushing into the open pipe end. If you flush from the open pipe end you run the risk of moving any blockage to another location.

The return runs very well. Yesterday I removed the radiator & on refitting the rad it began to heat but the bottom was cold I think it had heated from the return until it settled down & went cold. So are you suggesting to flush it through from the return side of this radiator. This rad is one on it's own in the kitchen in other words it's flow & return come in from the airing cupboard behind the hot water cylinder but I can only see one 15mm pipe. See my picture attached.
