Hi,
I have a pressurized hot water and heating system and need to top up the pressure to 1.5 bar since its around 1 at present. Its been ages since i did this so can't remember exactly I what i did previously but I believe i need to turn the valve under the blue vessel anti-clockwise a quarter and then do the same with valve under the red vessel to increase the pressure. Then once finished, turn valves in reverse directions.
Problem is the valve under blue vessel doesn't seem to move at all, I don't know if I'm doing something wrong or whether its stuck. Valve under red vessel is able to move a quarter anti-clockwise but it does nothing.
Any suggestions? Would really like to avoid having to call a plumber in, considering their call out charge is £80 alone!!
Thanks
