I've started a new thread for this - my previous thread dealt with a blocked 15mm feed to a rad. In sorting that problem, a new one has appeared. Vented system GlowWorm Ultimate 120FF New pump just over a month ago Motorised diverter valves checked (one valve was stuck and has now been...

Further to last post, the boiler has stopped banging completely and the amount of air being bled from the rads is getting less - albeit very slowly...A few of the upstairs rads are even starting to warm up....:) A couple of quickies if poss. 1) I had a quote of £300 for a complete...

Not at all, Tony.. The rest of the system has been OK. Whilst a couple of the other rads were not as hot as I suspect they should be, it was just one which was stone cold. I traced the blockage to an elbow in the 15mm feed to the rad, cut out an 18" length of the 22mm main pipe from which it...

I fitted the new pump and installed it in the same flow direction as the previous unit.

Top advice guys - many thanks for your help :D Will try not to get too wet tonight !!

Cheers, Chris - That's what I was hoping. I couldn't see that it would do any damage but thought it wise to check :D :idea: Nice thinking !! But how do you go about freezing the water in the pipe (sorry if the question seems a bit dim :oops: )

Unfortunately, I suspect I may know the answer to this question, but..... We have a downstairs rad that refuses to warm up. All other rads in the house are fine. The rad has been removed and flushed clean - very mucky and sludgy inside. We refitted the rad and it fills fine from the TRV...
