I have an issue with a cold/luke warm radiator in my new loft conversation and I think it might have been plumbed in wrong. I should add the plumber was kicked off the job and then I was abandoned by the builder so I had to finish things myself.
The pictures show where a different plumber connected to pipes that were left for him and as far as I can see the pipes, 6 in total are for hot and cold water and 2 radiator circuits.
I believe it has 2 circuits because the 1st plumber had a non-TRV bathroom radiator in mind so may have plumbed the bathroom rads separately?
The 2nd plumber though has just connected both circuits in parallel or possibly intended to and that is what I think might be my issue? I’m wondering if one of the rads is now on a circuit with either 2 feeds or 2 returns. Rather than break open the plasterboard wall can anybody suggest the best way I can test for this as I can access all the pipes from the airing cupboard. My hot & cold water work ok , 2 of the radiators work ok. Of the other 2 radiators one is cold but eventually gets Luke warm and the other has yet to be connected.
