Reply to "Sewage pumps premature failure"

We realized the pipe cracking was a symptom of something more we thought it was just torque hence the addition of the soft start. We realize later that once a section of the windings had gone even with the motor running the pump started bouncing around in the bottom of the like an asphalt compactor. So we switched to Zoeller pump number two model G295 – D (same as the first installed by the pump company) and in a week had the same problem assuming it was the soft start creating the problem we removed it. Rewired the same as the 3 previous, problem free years and installed a little giant model 20S – CIM again maybe got a week. Throughout this whole process voltage, amperage, and impedance have been checked thoroughly. Mathematically the pit only holds about 1400 gallons of water when at level which the pump will evacuate approximately a thousand gallons in five minutes. Leaving the pump in 3 to 4 feet of water. 10 foot of head is in the little Giants curve. Were thinking electrical only because the physical properties haven't changed years. Our original problem three years ago was 4 feet of muck in the bottom of the pit master a few changes in drainage it's now clean as a whistle.
