About this spa pump

This Waterway E-Series 1.5 HP spa pump delivers reliable 2-speed operation for most residential spas and hot tubs requiring 115V power. Built with Waterway's proven E-Series design, this dual-speed pump provides efficient filtration on low speed while delivering powerful jet action on high speed. The 48Y frame configuration and 16.4/4.4A amp draw make this a direct replacement for many factory-installed spa pumps.

At Bubbles Supply, we guarantee this pump will be an exact fit for your spa's original Waterway E-Series pump. Ships same day when ordered before cutoff, backed by our full 1-year warranty for complete peace of mind. This OEM-quality replacement restores your spa's performance to like-new operation. Verify your existing pump's specifications including horsepower, voltage, and amp ratings match before ordering to ensure proper fitment.

Common symptoms this part fixes

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

Before you buy — quick checklist

  • Confirm your existing pump is 115V — do not install a 115V pump on a 240V circuit
  • Match horsepower exactly — verify the label on your old motor reads 1.5 HP
  • Confirm your existing pump is a 48Y frame — measure or check your old motor's nameplate
  • Verify the pump is 2-speed — count the wires at the terminal: 2-speed pumps have separate high and low speed leads
  • Check plumbing union sizes on your existing pump before ordering to confirm compatibility
  • Note your spa's make and model and cross-reference the original pump part number against 3420610-15

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