  Cody MoralesAug 16, 2025
  If your Liberty Pumps Water Pump runs but doesn't turn off, there are a few potential causes. First, the pump may be airlocked. To resolve this, turn the pump off, let it sit for a few minutes, and then restart it. Ensure that the control panel selector switch is in the Auto position, not Hand. Check that the float switch can move freely without any obstructions. A defective float switch may also be the reason, consider replacing it. Finally, the control panel might have failed and should be checked.

  If your Liberty Pumps Water Pump runs or hums but does not pump water, several issues could be the cause. Check the discharge line for any blockages or restrictions, including ice if the line runs through cold areas. Inspect the check valve to ensure it's not stuck closed or installed backward. Make sure any gate or ball valves are fully open. If the total head (lift height) is too high for the pump's capability, consider routing the piping to a lower level or consulting Liberty Pumps about a larger pump. Clear any obstructions from the impeller or volute. If the pump is airlocked, turn it off, let it sit for a few minutes, and then restart it. You may also need to add a baffle to reduce trapped air bubbles.

Why Liberty Pumps 250 does not deliver proper capacity?
- P
  philip34Aug 31, 2025
  If your Liberty Pumps Water Pump isn't delivering the proper capacity, several factors could be responsible. Start by checking the discharge valve(s) to ensure they are fully open and not clogged. Inspect the check valve for partial blockages; try raising the liquid level up and down to clear any debris, or remove the check valve to manually remove any obstruction. For 3-phase motors, verify that the motor rotation is correct. If the total head (lift height) is beyond the pump's capability, consider routing the discharge piping to a lower level or consult Liberty Pumps about a larger pump. Ensure the liquid level is adequate. Finally, check for any obstructions in the pump or piping and remove them.

  If your Liberty Pumps Water Pump operates noisily, several factors could be the cause. Check if the piping attachments to the building are too rigid; if so, replace a section of the discharge line with a rubber hose or connector. For 3-phase motors, ensure the motor rotation is correct. Inspect the impeller cavity for any foreign objects and clean it if necessary. If the impeller is broken, consult Liberty Pumps for information regarding impeller replacement.

  Eric CollinsSep 7, 2025
  If your Liberty Pumps Water Pump is repeatedly tripping, several issues may be the cause. First, check if the circuit protection is underrated and replace it with the proper size. Ensure that no other appliances are on the same circuit, as the pump requires a separate circuit. Have an electrician check the wiring to ensure it is adequate and not compromised, and avoid using extension cords. Improper voltage can also cause tripping, so have an electrician check all wiring connections and voltage. Check for any obstructions in the pump and remove them. For 3-phase motors, verify the motor rotation is correct. Finally, clean the motor housing to remove any foreign matter buildup.
