ok.. So got called to this boiler as it was losing pressure, firstly checked for any leaky pipes / rads and nothing appeared at fault. Then inside the boiler on closer inspection i noticed that the manifold pipe around the pressure switch prv was slightly weeping and quite a large ball of limescale had built up around this area. Rather than just mearly cleaning the area i replaced the manifold pipe and re pressured the system and left.
6 weeks later i get a call again to say it has lost some pressure again, i am now thinking of replacing the expansion vessel as there is not much else on the circut. The boiler in question is a firebird combi. does anybody agree or have anyother suggestions as to where the pressure could be going.
Cheers alex
