I have a saunier duval boiler. Model no.THEMA CONDENS F 30E.
My boiler is less than 2years old and the pressure is regularly dropping, and we have to keep re pressuring the system. Surely this is a manufacturing weakness? Is this a common fault?

or an installer or customer problem. installer leaving small weep somewhere, or customer wanting boiler on old radiator system without re-newing pipework etc. pressure loss can not be pinned on manufacturer. if there was a part that was leaking im sure they would replace or repair.
