Worcester 24 cdi losing pressure daily

[Sparky1970]

Hi, a friend of mine has a problem with a worcester 24 cdi boiler, its losing pressure on a daily basis and they are topping it up nearly every day, there is no water leaking from vessel and the schrader valve is releasing air only, they have pumped it up previously but it doesn't appear to of worked, they say there is a small leak in the bathroom but its losing a lot more than the leak. any suggestions

I had a small leak on a radiator once and had to top up the pressure everyday. I don't think you need to lose much for the pressure to drop.

fix the leak, see what happens with the pressure.
