    Hi there,

    I keep getting an F22 warning fault code for my Valiant Ecotec Plus 637.

    With previous Valiant Boilers I had, I used to just turn the valves underneath the boiler to increase the pressure, but the 637 model doesn't seem to have the valves??

    I've attached pictures of my new Boiler set up, with Water Tank etc. Any help appreciated before having to call in external help.

    Thanks

    On of your pics of the hot water tank shows a switch on the wall with a silver flexi pipe infront of it, have a look there for a filling valve.

    Its a system boiler so they get filled externally, only combis have the valves built into them.

    This worked perfectly to boost the water pressure. Thank you very much.
