My boiler is leaking water and it's got quite bad recently. The pressure is just above 2 and the red marker is below 1. All the lights that should be illuminated are and no problem getting hot water or heating radiators.
The only thing I can think off is that the valve under the sink has been bumped. But I have no idea what is on or off. Can anyone confirm which angle is on and which angle is off.
Also any ideas of what is causing the leak?
