Hi
I inherited a 10yr old system. It was pumping over when I moved in and sludged up. The water was orange so I presume pumping over for some time. I have drained it a couple of times, & cleaned it out but still have the following issue:
Only when CH & HW is on at the same time the system pumps over into F&E. If I turn the pump down from 2 to 1 it's ok. I beleive the system has also had a fairly new vale for HW/CH. I dont think the boiler has been looked for ages either.
Couple of things to note: Boiler stat is on it's lowest (not sure if it's working thought) and cylinder stat seems to work ok.
What could be causing this?
Will having the pump on 1 damage anything?
Many thanks
Mark
