Waterway Bath Pumps
Need to replace a tub or whirlpool pump? This collection is built around Waterway Plastics bath pumps — the Genesis series you already see in many drop-in and alcove tubs. These pumps are designed, engineered, and made in the U.S.A. and are a go-to replacement when the original bath pump has failed.
What You’ll Find Here
- Genesis bath pump complete kits in 5.5A, 7.5A, and 13A ratings (≈ 0.75 HP, 1 HP, 1.5 HP) so you can match your old unit.
- Center-discharge Waterway pumps with 1-1/2" unions for straightforward swaps.
- Air-button operated models — works with your existing air switch on the tub deck (air tube typically sold separately).
How to Pick the Right Bath Pump
Match the amp/HP rating, voltage (115V), and plumbing size (1-1/2" unions) from your old pump. Waterway notes that 5.5A ≈ 0.75 HP, 7.5A ≈ 1 HP, and 13A ≈ 1.5 HP — so even if your old label said “1 HP,” you can match it by amps. That makes replacements a lot less guessy.
All our Waterway pumps require 1 1/2" Unions for install and air switch operated

Why Waterway?
Waterway is a longstanding U.S. manufacturer of pool, spa, and bath components, so parts are consistent and service-friendly — ideal for plumbers, remodelers, and DIYers doing a one-off tub repair.
Tip: If your tub’s air button or tubing is damaged, replace it at the same time you swap the pump to avoid coming back and opening the access panel again.
