    I have a 3/4 HP. Goulds JS07 from '93 that I suspect finally kicked the bucket. Two weeks ago we ran out of water, went out, turned off the pressure pump as it was VERY hot. Once our 1,000 gallon tank filled 3/4 of the way, I kicked the pump back on but it was unable to shut itself off. I had to lower the cut-in/cut-off pressure for it to shut off.

    Then comes just this last Tuesday, we ran out of water again! I'm thinking our well is slowly starting to dry up(sediment in water) as we were barely using any water, hell we were using laundromat to wash clothes. Anyway, when I discovered we were out of water I ran down to the well to shut off the pressure pump. Skip to Friday where our storage tank has barely filled to four rings(It's at 5 now), so I plug the pump back in and it starts working. But one thing I noticed is that it wasn't building any pressure at all. None of the fittings are leaking, so I'm thinking the pump has finally met its days, is this correct?

    Gary Slusser That's all folks!

    The first time it overheated the heat probably melted the impeller, jet etc. some and the next time it took them all out. Any Gould's dealer should have the parts or can get them.

    I'm having a little trouble getting that darn impeller out of there. I have the guidevane exposed, and I'm scratching my head trying to figure out just how to remove the thing. I have the parts list diagram but that seems to be of little help.

    The impeller screws onto the motor shaft. It may be left hand threaded.

    You hold the shaft with an open end wrench on the shaft inside the motor.

    Ok, got everything set up, bought a new nipple for the intake and discharge as I couldn't get the previous ones off. Pump turned on fine, gained pressure but when it shut off it started leaking out of the PVC unions. Not just in the ones that are on the pump, but one farther down.

    So tighten them up if you can though pvc unions suck and are prone to leaks.

    Chuck the unions!

    Unions on the suction side of any pump aren't a good idea.
