  If your Pentair Water Pump is losing suction, make sure the flange connections are tightened and sealed. Check the line for any blockages and ensure a clear water source. You may also need to increase submergence, lower the pump, or reduce suction line losses. Also, increase submergence to prevent vortexing. Check all connections and tighten if necessary. Finally, reverse any two motor lead connections and check the driver operation and maintenance.

  If your Pentair Water Pump has insufficient discharge, start by priming the pump to evacuate all the air. Check the drive speed and voltage. You may need to change the system, raise the wet well level, or install a larger impeller and driver. Increasing submergence, lowering the pump, or changing the system might also help. Ensure proper seal of flange connections and tighten them. Clean the impeller passages. Replace the impeller with a larger diameter one, and check the driver horsepower. Increase submergence to prevent vortexing.

  If your Pentair Water Pump is showing excessive power consumption, check the driver speed and voltage. Consider changing the system, reducing the pump speed, or trimming the impeller. Reducing pump capacity might also help. Check the motor/pump to base connections and realign the coupling. Determine the correct impeller diameter and replace or trim the impeller. Adjust the packing gland.

  To address vibration or noise in your Pentair Water Pump, start by realigning the driver and pump. Tighten foundation bolts and/or regrout. Open the discharge valve and check for obstructions. Increase submergence to prevent vortexing. Clean impeller passages. Also, increase system head, reduce pump speed, and trim the impeller. Check pipe supports and adjust or realign if the pump is improperly supported or aligned.
