    Hi all

    OK my problem is this.
    I have NO water supply to the sink in my shop.
    So I can fill a water butt everyday and connect to a kitchen sink tap.
    I will either use a submersible pump or stand alone (like a grundfos) pump to pump water from butt to the tap.
    My problem lies in If I use a flow switch to on/off the pump when the tap is turned on/off
    when turning the tap on for the first time, will the flow switch tell the pump to come on?
    Because there will be no flow to the tap unless the pump is on?
    And water is gonna be flowing up hill so I can use gravity effect to start the flow

    Go for a negative head pump, senses the loss in pressure rather than flow through the pump

    Or have your water butt at a higher level than the tap and no need for a pump.
