Boilder losing pressure

[richardadc]

I have a Gloworw 24ci boiler that recently has been losing pressure quite frequently with me having to fill up the boiler at least once a week where it drops from about 1.1 bar to 0.5 bar. There's an expansion vessel outside the boiler so i'm not sure if some point the one inside the boilder has failed? I've also recently taken a radiator off so i'm not sure if i've managed to damage the pipe work? There are no obvious water leaks that i can see.

Is it likely that there is a leak? I would of thought with that much water going i would see a sign of it? Thanks for any help.

It could be leaking from the PRV.
Check outside below the location of the boiler if its on an outside wall.
Look for a stub of 15mm copper pipe and see if its dripping.
Are you bleeding the rads often?
Check around your rad valves for leaks.
Must be leaking from somewhere.
Do you have pipework under floorboards or chased into walls?
If in doubt, get the experts out.

It is not likely you have a leak, you have one.
First suspect is prv.
