About this impeller

This 2HP impeller is designed for Waterway Executive spa pumps with 48 and 56 frame configurations. The precision-molded component features a 15/16" shaft length and 4-1/2" outer diameter, engineered to restore optimal water flow and pressure in your spa's main circulation system. The white dot marking indicates proper OEM specifications for reliable performance.

At Bubbles Supply, this genuine Waterway impeller comes with our exact fit guarantee, ensuring seamless compatibility with your pump assembly. We ship same-day from our Canadian warehouse and back every part with a full 1-year warranty for complete peace of mind. Before installation, verify your pump's horsepower rating and frame size to confirm proper fitment - improper impeller sizing can damage your pump motor.

Common symptoms this part fixes

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

  • Impeller visibly cracked, chipped, or broken on inspection
  • Grinding or rattling noise from pump housing
  • Pump cavitating or surging under load

Before you buy — quick checklist

  • Confirm your pump is a Waterway Executive model — do not assume by HP alone
  • Verify frame size (48 or 56Y) from the motor label before ordering
  • Measure your existing impeller's outer diameter (must be 4-1/2") and shaft bore (must be 15/16") before removal
  • Check whether your pump is single-speed or two-speed — impeller design differs
  • Inspect the wear ring and diffuser while the pump is open; replace if worn to avoid a repeat failure

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