About this impeller

This 1HP impeller is designed for LX 48 frame spa pumps, delivering the precise water flow your hot tub needs for optimal circulation and jet performance. Built to LX's OEM specifications with 3" suction line compatibility and 3-3/4" outer diameter, this replacement impeller restores your pump's original efficiency and power output.

At Bubbles Supply, we guarantee this impeller will fit your LX 48WUA pump perfectly – no guesswork, no returns. Every order ships same-day from our Canadian warehouse and includes our full 1-year warranty for complete peace of mind. When installing, ensure your pump is completely drained and power is disconnected before removing the pump housing to access the impeller assembly.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Weak or reduced jet pressure

Before you buy — quick checklist

  • Confirm your pump model number is LX 48WUA — check the label on the pump housing
  • Verify the 3" suction line inlet matches your existing plumbing
  • Measure your existing impeller outer diameter to confirm 3-3/4" OD before ordering
  • Check that your pump is a 1.0 HP unit — do not install a 1HP impeller on a higher HP pump
  • Inspect the pump shaft and diffuser for wear or damage before reinstalling — replace if needed
  • Confirm the impeller thread direction before removal (many spa impellers are reverse-threaded)

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
