Pump basket does not stay full of water; visible air bubbles and loss of prime.

Safety first: Turn off power before tightening fittings or opening the pump.

Steps to locate leak:

• Check lid seal: Clean and lubricate the Jacuzzi pump lid O-ring and ensure the lid is tight.
• Tighten unions: Hand-tighten suction-side unions and check for cracks.
• Use soapy water: With the pump running, carefully apply soapy water to suspected joints above water level and watch for air being drawn in.
• Inspect valves: Check suction valves for leaks around stems and bodies; replace if necessary.

Persistent air leaks may require replacement of cracked fittings or re-plumbing sections of the suction line.
