Troubleshooting

Diagnosis: A leaking Square D Pumptrol FSG2 switch indicates a ruptured internal diaphragm, a critical failure allowing water to contact 240V terminals. This requires immediate system de-energization and replacement of the switch to prevent electrical shock, fire, and catastrophic pump damage. The root cause is often a waterlogged pressure tank causing rapid cycling. In this […]

Diagnosis: A seized well pump from hard water presents as low pressure and white crust on fixtures. Calcium scaling cements the pump’s impellers, causing a locked rotor condition that can burn out the motor. Professional repair involves well acidization or pump replacement and installing a water softener to prevent recurrence. In this Guide: What Causes

Diagnosis: A Well-Mate tank that feels solid and heavy is waterlogged due to a failed internal bladder, which eliminates the critical air cushion. This forces the well pump to short-cycle, causing rapid overheating and catastrophic failure of the motor, bearings, and controls. Immediate system shutdown and tank replacement are necessary to prevent costly pump damage.

Diagnosis: Water coming from the air valve on your Amtrol Well-X-Trol tank indicates a critical failure of the internal diaphragm. This catastrophic failure eliminates the system’s pressure buffer, causing the well pump to short-cycle, which quickly leads to motor burnout. The only correct repair is a complete replacement of the pressure tank. In this Guide:

Diagnosis: When your water pressure drops to zero before the pump starts, the primary cause is an improper air pre-charge in your Boshart pressure tank. If the air pressure is set higher than the pump’s cut-in pressure, the tank empties completely before the pressure switch can activate the pump, causing a total pressure loss and

Diagnosis: A sputtering faucet indicates your submersible pump is sucking air, a critical condition caused by a dropping water table or a pump oversized for the well’s yield. This starves the pump of water, causing severe overheating and internal damage. Professional repair involves a well yield test and either lowering the pump or installing a

Diagnosis: If your submersible well pump runs but delivers no water pressure, a common cause is a ruptured drop pipe inside the well casing. This failure prevents water from reaching the surface, causing the pump to run continuously without load, which can lead to severe motor and bearing damage. Professional repair involves pulling the entire

Diagnosis: A rapid clicking sound from your Square D Pumptrol FSG2 pressure switch, known as short cycling, is almost always caused by a ruptured internal bladder in the pressure tank. This creates a waterlogged tank with no air cushion, forcing the pump to turn on and off constantly. Immediate power-down is critical to prevent permanent

Diagnosis: A buzzing well pump that fails to start is most often caused by a faulty start capacitor or a defective start relay within the external 3-wire control box. This failure prevents the single-phase motor from creating the necessary rotating magnetic field to begin operation, resulting in a loud hum and a tripped breaker. In

Diagnosis: If your well pump turns on when no water is running, you likely have a critical system leak or a failed check valve. This failure allows system pressure to bleed off, triggering the pressure switch to cycle the pump repeatedly. This guide explains the engineering causes, DIY diagnostics, and the required professional repair process.
