overflow

[aaa12]

hi

i have ideal c28 i guess, recently bought around 3 years ago.
last year i pressurised it to around 2 bar point i guess i correctly remember.

but what is happening now is bar point remains at 3 and whenever it starts off it drains water through overflow.

any advise please

Release the pressure by draining a rad so that it reads one bar and then disconnect filler loop. If pressure kees rising up to 3 bar you will need to get someone in to check your pressure vessel
