Evening all, looking for advice. Worcester Bosch 4000 boiler, exactly 2 years old. Serviced annually, just due it's 2nd.
Noticed lights flashing yesterday and pressure was .8. Usually check this fairly regularly but it's never strayed from 1.2. Topped up last night to 1.2 and it dropped to 1.1 in about 4 hours. Thought it might be settling, but today it's 1.0.
Have checked all rads and exposed pipework for leaks. Checked around route of pipes for damp patches but nothing obvious. Unfortunately 50% of pipes either under laminate or concrete so not easily inspected. However, would expect a leak to be pretty significant. Nothing seems to be coming from boiler expansion pipe - what is my best course of action at this point?
