  First, make sure there's enough space around the motor for air to circulate, which helps keep it cool. Also, have a qualified electrician check for any loose connections and measure the voltage at the pump motor while it's running. The voltage should be within 10% of what's listed on the motor's data plate. If it's not, you'll need to contact a qualified electrician or your local power service provider.

  Check the suction side piping union. While the pump is running, try tightening the union. If the air leak persists, turn off the pump. Loosen both unions and move the pump aside. Remove, clean, and reinstall both union o-rings. Reposition the pump and tighten the union nuts by hand. If they still don't seal, gently tighten with tongue-and-groove pliers, but be careful not to overtighten.

Why are there bubbles in my Jandy Power Pump basket?
- A
  Adam JohnsonAug 5, 2025
  Bubbles in the pump basket usually indicate air in the system. Check the pool or spa water level to ensure it's adequate, preventing air from being drawn into the suction piping. If the water level is normal, switch off the pump and check for debris around the lid o-ring seat. Debris can cause air leaks. Clean the lid o-ring and seat, replace the lid, and hand-tighten it securely. Then, turn the pump back on.

What to do if Jandy Power Pump pressure is low but there is no air?

  Debris might be caught in the pump impeller. The pump impeller moves the water, and the vanes in the impeller can become blocked with debris. See Section 6.2, Service Technician Maintenance, 6.2.1, Blocked Impeller, for more information.

  If your pump is leaking water between the motor and pump body, this is caused by a damaged or failed mechanical seal. Replace the seal. See Section 6.2, Service Technician Maintenance, 6.2.4, Mechanical Seal Replacement.

What to do if Jandy Power Pump impeller is not blocked and the pressure is still low?

  The pump impeller and diffuser are showing signs of normal wear. Have a qualified service technician check the impeller and diffuser and replace as necessary. If the pump is part of a relatively new installation, it could be an electrical problem. Contact a qualified service technician. Have the technician check for loose electrical connections and check the voltage at the pump motor while it is in operation. The voltage must be within 10% of the motor’s data plate rating. If the voltage is not within 10%, contact a qualified electrician and/or the local power service provider. The pump seal is leaking air. Have a qualified service technician replace the seal.
