For a detailed explanation, click here. Briefly, a common or neutral wire is run from the controller attached to the common terminal and is spliced into one of the two leads of each valve solenoid. A hot wire is then run from each of the remaining zone terminals to the remaining lead on each solenoid.

Several things could be happening. If the pump produces more water than the tank is sized for, cycling will occur. The tank should be sized for one gallon of drawdown for each gallon per minute of water pumped. The pressure switch may be adjusted incorrectly. There should always be a 20 psi differential between the cut-on and cut-off pressure and the pressure on the tank should be 2psi below the cut-on pressure.

A multi-stage pump utilizes more than one impeller in the pumping chamber.  These pumps are used to lift water on properties with elevations in excess of 25’.  All submersible well pumps are multi-stage pumps.

1.  Leaking suction line.
2.  Stuffing box packing worn or water seal plugged allowing leakage of air into pump casing.
3.  Air pocket in the suction line.
4.  Not enough suction head for hot water or volatile liquids.
5.  Air or gases in liquid.
6.  Suction lift too high.
7.  Grass or trash sticking to strainer then floating off.

1.  Speed too high.
2.  Head lower than rating, pumps too much water.
3.  Wrong direction of rotation.
4.  Mechanical defects:
          a)  Shaft bent.
          b)  Rotating element binds.
          c)  Stuffing box too tight.
          d)  Wear rings worn.
          e)  Bearings worn.
          f)  Casing packing defective.
          g)  Pump and drive unit misaligned.
