    How to fix a Liberty Pumps LEH Water Pump that will not run?
    • S
      Shawn FlemingAug 11, 2025
      If your Liberty Pumps Water Pump isn't running, there are several potential causes. First, ensure the unit is securely plugged in and have an electrician inspect the wiring for proper connections, voltage, and capacity. Another cause may be that the switch is obstructed; reposition the pump or switch for adequate clearance. Also, the liquid level might be insufficient, so ensure it rises enough to activate the switch. Finally, the switch itself may be defective, in which case you should remove and replace it.

    What to do if my Liberty Pumps Water Pump runs but doesn't pump?

      If your Liberty Pumps Water Pump runs or hums but doesn't pump water, start by checking the discharge line for any blockages, including foreign material or ice. Next, examine the check valve to ensure it's not stuck closed or installed backward. Also, verify that any gate or ball valves are open. If the total lift is beyond the pump's capability, try routing the piping to a lower level or consider a larger pump. Lastly, the pump impeller might be jammed or the volute casing plugged; remove the pump, detach the base, clean around the impeller, then reassemble and reinstall.

      If your Liberty Pumps Water Pump won't turn off, it could be due to a couple of reasons. First, the switch might be obstructed, preventing it from moving to the 'turn off' position; reposition the pump or switch to ensure it has adequate clearance. Alternatively, the switch itself may be defective, requiring you to remove and replace it.

    How to reduce noise from a Liberty Pumps Water Pump?

      Emily WrightAug 30, 2025
      If your Liberty Pumps Water Pump is operating noisily, there are several potential causes. Start by removing the pump from the basin, detaching the pump base, and cleaning the area around the impeller to remove any foreign objects. Also, piping attachments to the building may be too rigid, so replace a portion of the discharge line with a rubber hose or connector.

    Why does my Liberty Pumps LEH Water Pump run intermittently when no fixtures are being used?
    • J
      Jo KingSep 4, 2025
      If your Liberty Pumps Water Pump runs periodically when fixtures aren't in use, it could be due to a check valve issue or leaking fixtures. Examine the check valve to ensure it was installed, isn't stuck open, and isn't leaking. Also, repair any leaking fixtures to eliminate the unwanted water flow.
