  If the Star Water Pump runs but doesn't empty the sink, several issues could be the cause. First, the drain might be clogged; clear the drain screen. Second, the discharge line could be blocked; unplug the pump and clear the discharge line. Third, the shut-off valve might be closed; slightly open the shut-off valve. Also, the system discharge line may be too high or too long; unplug the pump and reduce the height or length of the discharge line (11 ft. max. height). Finally, the check valve might be installed backward; ensure the flow arrow on the check valve points away from the pump.

  If your Star Water Pump won't run when water flows in from the sink, there are several potential reasons. First, make sure the pump is plugged in. Second, check the fuse/breaker to ensure there is power to the outlet. Third, the pump impeller might be jammed; unplug the pump and follow the procedure under “Maintenance” to clear the pump. Finally, the sink stopper might be in the drain; remove the stopper.

  If the Star Water Pump cycles on and off when no water is in the sink, it could be due to a check valve issue. Ensure a check valve is installed; if not, unplug the pump and install one. Alternatively, the check valve might be jammed; unplug the pump, open the discharge line, and clean the check valve.
