    Hi,
    I am new to this site so bare with me....
    I have just bought a compass advantgaurde 400 RL 04 plate, fitted with an ultrastore rapid,
    My problem is that when I charge the boiler with water and go through the process of purging the system the whole water tank discharges through the
    Ventilation hose on the boiler which makes sence as the boiler is lower than the storage tank
    It just syphones out of the boiler.
    I am probably missing something as I don't have a handbook yet. Is there an anti-syphones valve that may be faulty or am I missing something?.
    Any advice would be apreciated...

    Ok I have tried the reset on the valve but it is still siphoning out, maybe the valve is faulty I shall order a replacement and update the thread accordingly.
    Thanks lads for the input.

    Try lifting the valve lever fully and putting a cloths peg round the exposed spindle.

    that way it wont work at all....even when it freezes....but will get you going for now

    there is also a fusible valve that releases the water if it overheats. this is the red bit at the boiler end of the tube and needs replacing if it leaks

    Thanks for all your help I have found the problem, the unit has a top 10mm elbow fitted to the boiler,but it's the wrong one.. It should have an elbow with an integrated breather valve and the elbow fitted don't have one.
    My next nightmare is finding. A good PDF down load that will show the correct part. Again thanks to all...
