I have a Betacom 2 24 boiler with 0.0 bar of pressure. This is something I’ve been able to fix easily on other boilers and don’t want to have to call out my landlord for what should be a simple fix. The valves just don’t make sense or don’t do what I think they should. There’s a valve connected to a hose separate to the main boiler which sounds like it’s letting water in, but no second tap/valve I can see. Trying the one that is there on its own doesn’t affect the pressure.
Any ideas?
