Pump is very noisy, with a loud grinding or screeching sound from the motor area

Safety first: Turn off power at the breaker before touching the pump.

• Confirm noise source: Place your hand lightly on the Aquaflow motor housing (with pump briefly running) to confirm the noise is from the motor, not the plumbing.
• Check for leaks: Inspect the area between the pump housing and motor for water drips, which indicate a failed mechanical seal that may have damaged the bearings.
• Short-term use: If the noise is minor and there is no overheating or tripping, the pump can sometimes run temporarily, but bearing failure will worsen.

Motor bearing replacement requires disassembly and press tools; most homeowners replace the entire Aquaflow motor assembly or pump head.
