Hi, I hope someone can enlighten me?
I have had my boiler installed for 5 trouble free years, but recently the ch side was showing low pressure when the heating was not on. I topped up the boiler and left it. When I went back to check later when the ch was on the pressure was over 2.5? I checked again when the ch was not on and again the pressure was down??
I have checked the radiators and cannot find any leaks and cannot see any signs of water seapage on any ceilings or floors where the pipes run.
I don,t want to keep topping the boiler in case it goes totally over pressure.
Any help will be gratefully recieved.
Many thanks in advance
