First, ensure the unit is securely plugged in. Then, have an electrician inspect the wiring for proper connections, voltage, and capacity. Also, check if the switch is obstructed, preventing it from turning on, and ensure the liquid level is sufficient to activate the switch. If these steps don't resolve the issue, the switch may be defective and require replacement.
Why does my Liberty Pumps Water Pump run or hum, but not pump?
This can occur if the discharge line is blocked by foreign material, including ice in cold areas. The check valve might be stuck closed or installed backward. Ensure that any gate or ball valves are open. The pump's total head (lift height) might exceed its capability, requiring either lower routing or a larger pump. Lastly, the pump impeller could be jammed or the volute casing plugged, requiring cleaning.
What to do if my Liberty Pumps Pro380 will not turn off?
If your pump won't turn off, the switch may be obstructed, preventing it from moving to the 'off' position. Ensure there's adequate clearance for free operation. If the switch operates freely, it may be defective and need replacement.
How to fix a Liberty Pumps Pro380 that operates noisily?
Noisy operation can be due to several factors. There might be foreign objects in the impeller cavity, which requires removing and cleaning the pump. A broken impeller or worn bearings could also be the cause, requiring you to consult Liberty Pumps for impeller replacement or return the pump for repair. Also, check if the piping attachments to the building are too rigid; replacing a section with a rubber hose might help.
Why does my Liberty Pumps Water Pump run periodically when fixtures are not in use?
This issue may arise if the check valve is missing, stuck open, or leaking. Remove the check valve and inspect it for proper installation and free movement. Another possibility is that fixtures are leaking, so repair any leaking fixtures to stop the pump from running unnecessarily.
