Mend Glowworm Swiftflow Boiler Heating Pressure

glowworm/combiboiler/swiftflow?

looses water pressure when in stand-by. when you recharge the pressure and use it the system goes upto 2.5 bars pressure, then drops below 0.5. in stand-by
the minimum pressure should be 0.7 wich is what i charge it to.

Check the pressure in the expansion vessel using a tyre pressure guage when the system is under zero pressure. It should be about 0.8 bar. If not pump it up with a bicycle pump.
