after reporting pressure drop, replies came in re the expansion tank suggesting it probably needs pressurised, I want to check this.
how is it done, and where is the valve for attaching pump
cheers boys
pressure keeps dropping and shutting down boiler, no visible leaks, boiler cuts out at .6 bar, I fill to 1.5 bar, everything ok for a few hours, new pressure valve fitted, overflow still dischrges water.
help please
