    Through a very kind Funster I took the motorhome to a lovely man near Limoges yesterday. He sorted a couple of things for me and changed the gas over to French.

    However, when we filled it with water and switched the pump on, it wouldn't switch off. Just kept running even when we turned taps off. Phoned the dealer where I bought it and they said it could be small leak that makes the pump think it still has to keep running--but I can't see any leaks from taps, pipes under the worktop, under the bathroom basin.

    I have to find someone here who can look at it--not easy in the middle of nowhere (or so it seems at times) Just wondered if anyone had any ideas of what it might do, so that if I find someone and they start to tell me "stuff" I might be able to make sense of what they are saying.

    Sorry--does this make sense?

    Internal pump leak such as diaphragm may cause this problem so no leaks to see as such. Make and mode of pump may help others to help you

    It would also be useful to know whether the pump runs continuously or cycles on and off. If it runs continuously and there is a leak then it is a big leak then there will be lots of water so you should be able to find it. It may well be a fault with the pump as Geo says in which case it would be worthwhile replacing it. Some of them can be serviced but if you have to pay someone to do it then it may be cheaper just to replace it.

    Thanks, The pump just runs constantly--doesn't stop or pause and restart.

    It says Superflow 126 PRO on it. Does that help at all?

    I can't see any water leaking anywhere at all and there was none yesterday either.

    It could well be the pressure sensing switch stuck or faulty, give the pump a tap with a hammer (not too hard!)

    Temporarily you can switch it off by removing a lead

    I'll try the hammer--gently, wrapped in a towel I think.

    [HI]Temporarily you can switch it off by removing a lead[/HI] Do you mean switch off the pump or the sensor?



    There is water in the tank. & can't see any leaking in or outside m/home.

    If you have a separate switch for the pump, use that.

    The pressure switch is on the end of the pump where the wires are connected, you may be able to adjust it, (cant remember!)

    Just checked, there is an allen key adjuster for the pressure switch.

    Right then :Smile:IF after tapping with hammer fails,next is adjust pressure switch and if that fails you have two choices get a repair kit (quite cheap) or fit a new pump :thumb:
    Once you remove the pump get the hammer again and smash it to bits (feels good :BigGrin:)

    Thanks. It's under warranty still from purchase of van. Will try the hammer tapping later and see what happens.
    You've all given me plenty of clues and alternatives so hopefully it'll be fixed/replaced if necessary soon.

    if its not on a pressurised system one of the switches under one of the taps could be faulty.

    I agree, does sound like a faulty microswitch could be to blame. If they do not go 'off' fully, the tap will stop running water, but the pump will continue, even if no water is coming through. Cost about 30p.

    The Sureflow should be used on a pressurised system :thumb: When did you last buy micro switches ?The last I bought about 7 /8 yrs ago were around 4 quid :BigGrin:
    just looked on ebay £3.50 each :Wink:

    Thanks for all your suggestions. Now managed to find mechanic who has come out to the house (going to motorhome place recommended involves 2 and a half hour drive each way) he thinks it is a loose connection or possible a dodgy switch. But he can fix it!!!:Smile:

    It's still under warranty but don't really want to drive from Dordogne to Southampton if I can avoid it.

    And I so wish I had a fraction of your mechanical knowledge.

    Be careful what you wish for.
    My mechanical knowledge gets me into far deeper s**t, than your lack of it ever will:Rofl1::Rofl1:

    I only paid 30p last year - either they messed up, or I am going to start selling them on Ebay! :Rofl1:
