I normally stick to electrics, thought plumbing was easy as you can see the contents, how wrong could i be, stick to my day time job i think!!!!

It's definitely a flow issue for sure, the system water is quite clean and has always had a good dose of inhibitor (very hard water area) so i hope not sludge. The rad tee'd from is not last in the system, in fact only about 5 meters away from the pump! As it's microbore aren't all...

OK so i guess this is a lesson learnt, my only curve ball is why when the existing rad i tee's into is turned off do i still have this problem? pipes have been tee's about 12" back from existing rad. If it were a balancing issue with the new rad fully open shouldn't this be taking the flow...

Yes, the rad i tee'd into is very small (500x500 single) the valve is backed right off, about 1/8th of a turn open following a balance last year, this rad gets hot at the same rate as all other rads, i would have thought there was plenty of enough excess flow to this rad. Just turned every...

Exactly, the pipe run has one inline half way along (had to do this whilst builders built studwork to cap off and keep house heating working) and then connected to the rad valves, each run has 4 of these seal inserts in place.

The whole house is 10mm, so i just went like for like, only thing is it's 10mm copper, i have put in 10mm plastic with these seal inserts that have 5mm internal diameter!! Just can't work out why they would restrict pump flow and not gravity pressure flow with valves open to air. Haven't shut...

I'll try to explain as best I can! Newish build house (1994) has 10mm microbore heating pipework, gravity fed CH system. We have just converted out garage into a day room and added a radiator, I decided to tap this into the radiator feed from the bedroom above, firstly because it was a...
