Wayne 2 HP Sprinkler Pump: Impeller Slipping on Shaft

Pump Failure: Plastic Impeller Loose on Motor Shaft

After little use, Wayne pump pressure dropped to zero. Impeller slips on shaft (marked, motor run, mark moved). No visible setscrew or key.

Repair Reality

Many residential pumps have pressed-on plastic impellers that aren't serviceable. Rebuild kits are rare.

Best Option

Find a local pump repair shop that rebuilds units. Much cheaper than new pump. Search "pump repair + your city".

If DIY

Some impellers have a hidden setscrew under a plug, or use a keyway with a roll pin. Inspect closely with magnifier.

But given age and "out of warranty," professional rebuild is recommended.
