Hi
I have installed new rads with pipes running across loft then down walls to rads.
I took feed of 15mm flow/return and t'ed off for each rad.
The first rad is heating up fine but rest are not.
Pressure is at level on system and I have turned other 4 rads off unscrewed valves at top of each rad and open valves.
Couple of them heated then went cold again.
Any ideas?
Thanks
