    ATK pump losing prime/power

    My ATK has been running fine for a few months. Just last night I noticed the pump was running for a while with no water coming out the orange tube.
    I checked the tube for blockages and the pump impeller etc- all find. Pump has only ever been used with RODI water - no kalk or anything else.
    When I disconnect the orange tube from the pump then turn the pump on it pumps water fine .
    Seems to be a loss of head pressure/pump power ? (The tube is only about 5ft long )
    Anyone else had a similar issue ?
    Cheers

    I've occasionally had the orange tube slip off the PMUP, It's happened about 4 times. I cut the end off the tube and started with a fresh tube end after the last time. I guess taking it off and on to take the pump to the sink for cleaning has a down side in it stretches out the end of the tube.

    I’d try turning the pump on with the tubing connected but have all the tubing down in the bucket. Essentially zero head pressure. If it pumps then slowly raise the tube end higher and higher and note at how many feet above the pump you can raise it before it stops pumping. If it stops easily your pump has lost pumping efficiency for some reason. Do normal pump maintenance.
