Hello all.
I have a combi boiler and heating pipes have manifold upstairs. I want to flush heating system and radiators but do not want to touch valves on boiler in case they start to leak.
To save taking off all radiators could I take off one side valve from 1 radiator. Turn flow / return off to all others then on the radiator with valve removed open flow and return seperate and use filling loop to flush out pipe and radiator. Then repeat around all radiators.
