Microbore

[Riley]

Help my sanity

cust had one rad not working on microbore system.

I have unblocked today and rad gets toasty now all bar their towel rad upstairs are not heating up. Has to be air right? I just cannot chase it out of the system. Any ideas???

cheers

Assume you have tried all the usual tricks - turning all other rads off (also hot cylinder off if not a combi system) & maybe turn pump speed up & run for a few minutes?
If all else fails I run each rad valve through a hose but that will be a pain to do on a towel rail

Forgot to say that all rads bar the one I unblocked are On double valves. Flow and return on same side. Nightmare can't even attach a hose
