    Hi - Pressure on combi boiler from sealed system keeps dropping to 0.5bar which means i keep having to open the valve to get it working. When i increase pressure at only one bar the pressure valve of the boiler starts releasing water. What is the likely problem ? This has never happen before - normally i would have to increase the pressure significantly for the pressure valve to release water.
    THanks

    I would suspect that the pressure gauge itself is faulty.

    Cheers Guys - Really appreciate your help.

    So if the prv is just passing - i would be supprised due to only 1-1.5 bar of pressure. I would have thought it would take more before it would pass.

    So how do i release all pressure from this potterton puma and how do i clean the prv valve seat ? Is this something a lay person :oops: can do or should I call in specialist help

    Thanks again and Happy Xmas to you both
