Vaillant Boiler - Pressure running high
 

I have a Vaillant combi bolier (about 10 years old) with the pressure guage jumping to the max all the time. I have to use the pressure release tap to release the excess water once every week to every two days! I know the pressure represents the amount of water store inside the boiler, so is it a problem with my top-up tap that slowly letting excess water into the boiler or there's something else?

Thanks for any help or suggestions.

Could be the tap letting water in.

Yeah, apologies, but because of the nature of Usenet
not all posts appear at all nodes simultaneously
so his wasn't apparent to me.

But thanks anyway,

Lower water to the proper level and turn off the auto fill valve, if the
pressure then climbs dramaticly when the water is heated it is the
expansion tank. Auto fill valves go bad just leave it off if it is the
cause
