radiator cold on a one pipe system

[danny_090]

just been to a job where the radiator is warm at the top cold at the bottom and its on a one pipe system. I am going to put a cleaner in the system anything else I can do without powerflushing it

You'll be good if you can powerflush a one piper

 

[danny_090]

any suggestions what I can do

 

[tamz]

Make sure the valves are clear and the pipes to the rad are short and rise slightly.

 

[danny_090]

yes everything seems ok was thinking of taking rad off then putting a hose in it to flush it thru

 

[tamz]

Won't do any harm. If there is a std trv fitted remove it as they have too much resistance.

no hasn't got trv on it I think its the last one on the system so wont be as hot anyway. what im thinking of doing is putting a cleaner in leaving it a week while ive got it drained down take the rad off and flush it thru
