Hi, Out Worcester Bosch combi boiler presure keeps on gradually falling. Does this indicate a small leak somewhere in the system, or can there be another cause? Thanks Ad

Loss of pressure=loss of system volume i.e a leak. Change the 900 to 670 in the return email address to reply
Failure in the pressurised resovoir so that the gas pressurant leaks out. However, a leak is far more likely.
See last FAQ below.
hi, check outside for any signs of water coming from the pressure relief valve outlet - the valve can be replaced by a reasonably competant diy-er, if that is the problem. How old is the system? Hugh
