Built specifically for LX 56WUA pump configurations, this wet end delivers the reliable water circulation your spa needs.

Engineered to LX's exacting standards, this wet end features the robust 56Y frame design that handles high-flow applications with confidence. At Bubbles Supply, we guarantee this is the exact fit for your LX pump setup, and we'll ship it the same day you order. Plus, every wet end comes backed by our full 1-year warranty for complete peace of mind. Before installation, verify your existing pump's frame size and connection threading match the 56Y specifications to ensure proper fitment.

Common symptoms this part fixes

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

  • Wet end cracked or visibly damaged
  • Impeller worn or broken causing low flow
  • Seal leak causing water around pump housing
  • Loss of prime or no water movement
  • Grinding or cavitation noise from pump
  • DR error code on spa controller indicating flow failure

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your existing pump motor is LX 56Y frame — the wet end mounts to the motor, not a complete pump
  • Verify both suction and discharge ports are 2-1/2" MBT threading — measure before ordering
  • Check the HP rating on your existing pump label matches 5.0 HP
  • Inspect the motor shaft to confirm it is in good working order before replacing only the wet end
  • Confirm your spa plumbing uses 2-1/2" fittings or adapters compatible with MBT connections

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