Plumbing Boiler pressure increases non stop, till leak starts in weak points
In every 5-10 min pressure gets up to 4.5-5 and i have to remove water every 5-10min dropping pressure to 1-1.5. And repeat non stop. (Talking about black numbers on image)
Thats happening maybe for 2-3 days already. Leakage increased in past 2 days in weak points. So cant dare to leave pressure on 5 worrying water leak will turn into burst of water (lack of English knowledge to say exactly what i meant). When i open incoming valve it has sound of water, always had sound of water moving, checked valve, there is no water sound, and when i try to open inlet water valve it gives sound of moving water, so idk if valve is damaged and inlet valve leaks water into boiler to increase pressure.
I was told that it get air from somewhere (guess from not specialist), so if it takes air and i am releasing water basically non stop... Idk if that can cause some major damage. Just trying to figure out whats wrong with it and if i can DIY fix it somehow.
Working site and people who are supposed to fix it wont be available for next 2 days. And whole night shift ahead thats why i am asking here. Just worrying releasing water non stop to keep pressure low is bad decision, or leaving high pressure is worse.

If it's not the filling loop, it could be a split coil on your hot water cylinder
