Shack,
So they recommend putting it up 20 to 40 feet. That's weird. It would seem to me if you install a check valve above a pump 20, 40 feet, the pump shuts off, a vacuum is created by the water falling down to the water level or as far as it can. Then on comes the power and wham, the water column takes off at the speed of sound smacks the poppet and bang goes the water hammer. I'm not sure just how many of those whams the check valve poppet can take.
