greenstar 24i junior boiler pressure keeps falling

[m ray]

The system pressure gauge keeps falling to zero almost daily. I have checked all radiators, and the out pipe isn't leaking. I refill to 2 bars but by the next day it's down again. The boiler is 10 years old but we have never had a problem with it and the heating is fine. Please advise. M.Ray

If you can get to the safety discharge pipe outside (15mm copper) tie a plastic bag on end that way you will see if its leaking, if no leaks showing in doors, it could be under the floor, anything else and you will need to call someone in to check boiler.

basically you need a boiler technician to trace and fix the fault, normally an easy fix.
