    Hi,

    I recently drained my water system as we had a warning of frost. I did this by opening the drain valve by the Truma boiler and opening all the taps.

    When I recommissioned the system to get the van ready for a trip I could not get all the air out of the system, that is, the pump runs on for a few seconds after I shut the tap. I have run quite a large amount of water through both taps and the shower head but still have the run on problem.

    Any ideas?

    Hi, Bill, could be that it is filling the heater tank up before the pump goes off. Is it ok after it has gone off or does it still run? try opening the taps on the "hot" side, this might ensure the tank is full.

    Could be one of two things.
    a/ the pump or line STILL has air in it, in which case you're just gonna have to put up with it until it decides to spit it out
    or
    b/ the shut off needs adjusting, not uncommon and easy to do..

    Hi,
    Just a thought.
    Have you flushed the toilet to purge the air from it?

    We've used the van for four days using almost a full tank of water and still the pump runs on for about 3-4 seconds longer than normal.

    I'll try purging it again but search for a better solution as with this current weather I am draining and re-filling quite often.

    Many thanks for everyones suggestions.

    Hi Bill

    Getting rid of air locks can be a real pain..

    I had a problem with air getting in due to a slack connection on the suction side of the pump.. .. worth checking !

    If you have a strainer you can watch for air bubbles..
