    Hi

    Ive recently moved to a new house with a Vaillant 828E boiler , the boiler seems to work fine but i have no pressure reading on the gauge ? it also had a leaking coming from the auto air vent on the pump , Me and my brother in law drained the system today and replaced the auto air vent that was leaking we also fitted a new gauge but still no reading ? We checked the expansion vessel which seems fine ?

    We refilled the system by ear , listening for when its full , i think we have it about right but who knows without the gauge

    Any ideas ?

    Thanks

    Could there be a blockage at the connection for the pressure gauge. Drain again, disconnect gauge and stick something in the hole to clear.

    How can you over pressurise by touching the PRV? If it's over pressurised, just let some pressure out. If it's leaking, keep opening it briefly, see if it's stopped dripping. If not keep opening it until you flush the debris out. If not, put a new one.

    Also, stop playing with the PRV. It shouldn't be used to drain the system.

    if you have to fill without a gauge dont use your ear for gawds sake.

    get someone to fill up while you bleed. when water comes out the top of the uppermost rad leave it at that.

    Ok , Just an update

    All fixed put a new PRV on and alls good

    I think my brother in law left one of the filling taps open by accident so when i touched the PRV it let all the water out the back of the house ? as i had no gauge i couldnt tell what was going on with it

    But seems good now and i didnt have to pay an engineering £300 as per quote from British Gas

    Thanks for the help :)

    A reasonable independent would have only charged about £84 plus the cost of any parts.

    Thats often a lot less that BG who have to pay dividends to shareholders and maintain an army of administrators!
