Why is my Liberty Pumps LGV02 not delivering proper capacity?

  David WatsonSep 8, 2025
  If your Liberty Pumps Water Pump isn't delivering the expected capacity, consider the following: * Check the discharge line for any blockages, including ice in cold areas, or a partially closed discharge gate valve. * Raise and lower the liquid level to try and clear a partially clogged check valve, or remove the check valve to clear any obstructions. * For 1-phase pumps, verify the capacitor wiring. For 3-phase pumps, correct the pump rotation direction. * Ensure the liquid level is sufficient. * Remove any obstructions in the pump or piping. * If the total head is beyond the pump's capability, consider routing the discharge piping to a lower level or consult Liberty Pumps about a larger pump.

Why does my Liberty Pumps LGV02 Water Pump cycle too frequently?

  Shannon WilliamsSep 12, 2025
  If your Liberty Pumps Water Pump is cycling too frequently, consider these potential causes: * Adjust the float switch setting. * Install check valve(s) if missing; if installed, remove and examine the check valve for proper operation and installation, as it may be stuck open or leaking. * Verify the presence of a curb stop check valve, and replace the curb stop/swing check valve assembly if missing or faulty, as it may be allowing system pressure to feed back through the discharge piping.

  If your Liberty Pumps Water Pump does not start and the overload heaters trip, here's what you can do: * Turn off the power and check the motor leads for a possible ground. * Check the resistance of the motor windings. All three phases should have the same reading if it is a 3-phase motor. * Remove any obstructions from the impeller or volute.
