  4. Install new packings in the correct order and orientation; lightly pre-lube.
  5. Set packing nut/wet-cup just tight enough to stop leakage; re-check after break-in.

Tip: If pressure fluctuates after rebuild, re-torque fasteners and confirm inlet screen cleanliness.

When to Rebuild / Replace

  • Loss of prime or audible cavitation from the lower unit.
  • Material weeping at the throat/wet-cup area.
