    Hello,

    Urgently required advice.

    Hava a Valiant boiler on which the pressure gauge has dropped from 1.5 to 0 and a leak all down the back of my house from a pipe exiting the boiler from inside thehouse to outside through the wall.

    Have read posts about doing something with the filling loop silver pipe but not quite sure how to proceed step by step.

    Found that a nut was loose and have tightened it. This has stopped the internal flow of water to the farmost right copper pipe.

    there is a cross shaped screw under the boiler by the silver flexible hose. DO i need to tighten or loosen it? Can I do it at any time or does the boiler / water have to be on/off?

    PS: I have the instructions but they make no reference to the fillng hose so I am not sure if they are complete.

    I have used the grey knob as desrcibed. This made a clunk and there is no more water leaking from the back of the house.

    NOw I have also found the screw on the silver hose. I have unscrewed it completely and nothing happens. The pressure is at 0 since I used the grey knob.

    What else do I need to do now to repressurize the tank?

    PS Thanks in advance

    John

    you will need to open two screws follow the silver hose to another brass block open screw on this pressure will rise
