Pressure Loss on Combi Boiler


Postby spider13 » Mon Jul 09, 2007 7:26 am

Before I lift any more carpet and boards, could there be any other reason for a frequent loss of pressure, other than a water leak somewhere in the central heating system/pipes/rad's etc.? Boiler is only 2-3 years old and losing pressure/needs topping up every few weeks. Can't find any damp, wetness anywhere in the house. Please help.
Thank you
