Why RIDGID SP-330 Water Pump will not start or run?
- G
  Gregory MorganAug 11, 2025
  Several factors can prevent your RIDGID Water Pump from starting or running. It could be due to a blown fuse or breaker, in which case you should replace the fuse with the correct size or reset the breaker. Low line voltage (under 108 volts) could also be the culprit, so check the wiring size. Other potential causes include a worn motor (replace the motor or pump), a worn switch (replace the switch), an impeller that won't rotate (remove the housing and clear any blockage), or a float obstruction (ensure the float moves freely).

  If your RIDGID Water Pump is starting and stopping too frequently, consider these potential causes: a backflow of water from the piping (install or replace the check valve), a defective switch (replace the switch, applicable to SP-330, SP-330-D, and SP-500 models only), or a dirty solid-state water sensor (clean the sensor face, relevant for Model SSP-1000 only).

  If your RIDGID Water Pump is running but not delivering enough water, or no water at all, check for these issues: low line voltage (if it's under 108 volts, inspect the wiring size) or a plugged impeller (clean out the impeller).

Why RIDGID Water Pump will not shut off or thermal protector turns off?
- L
  Lisa EvansAug 29, 2025
  If your RIDGID Water Pump won't shut off, or the thermal protector keeps turning off, the cause may be a dirty solid-state water sensor (for Model SSP-1000 only, clean the sensor face), a defective switch (replace the switch), an obstacle in the piping (remove the pump and clean both the pump and the piping), or a float obstruction (ensure the float can move freely up and down).

What causes gurgling sound from RIDGID SP-330 at end of cycle?
- B
  Brittany SimonSep 3, 2025
  A gurgling sound from your RIDGID Water Pump at the end of its cycle can be caused by air ingested into the pump (wipe off the surface of the sensor) or because the time required for pumping is less than 4 seconds (additional run time will not damage the pump).
