Preventative Maintenance Tips

5 Indicators to Determine if Your Pump Needs Serviced

Our pump experts compiled a quick checklist you can use to see if your pump needs to be serviced or repaired. If you answer yes to any of these questions, please fill out this form to connect with an Authorized Distributor who can inspect your pump and provide any necessary maintenance or repairs using OEM Parts.

Pump Health Check

1. Check Your Maintenance Log
  • Does the maintenance log indicate the pump has not been serviced in a year or more?
    • If there is no maintenance log kept after one year of operation, the pump needs to be checked.
    • If you do not have a maintenance log, you can download ours today
2. Look Closely At Your Pump
  • Is there water leaking from your pump?
  • Do you see any corrosion around your pump?
    • If your pump is leaking, it can cause a safety hazard and lead to wasted fluid.
  • Is the pump failing to reach speed and pressure installation conditions?
    • For more information on your pump’s installation conditions – please contact your Authorized Distributor.
  • Does the pump’s controller display any impending or present alarms or alerts?
3. Listen To Your Pump
  • Does your pump emit a grinding or high-pitched noise?
    • A grinding noise may be due to improper alignment, which could shorten the impeller’s life.
    • If you hear a high-pitched noise, it could be an issue with the bearings.
4. Take the Pump’s Temperature
  • Using a temperature gun aimed at the bearing arm, is your pump running hot as defined by your pump's specs? Check your pump's Operations Manual for exact temperature limits.
    • If your pump runs too hot for long periods of time, it could lead to your motor burning out.
5. Conduct A Vibration Analysis
  • Does your pump’s vibration exceed the Hydraulic Institute® Standards?
    • If so, it may need to be realigned or the impeller may need to be replaced.
  • Pentair recommends pumps get realigned annually.

If you notice any of these issues with your pump, please contact your Authorized Distributor to schedule a service call.
