About this wet end

This LX 48Y frame wet end assembly is designed for LX spa pumps requiring a 1.0HP replacement component with dual 2" MBT (male buttress thread) connections. The WE-48WUA1001CII wet end features the standard 48Y frame configuration commonly found in residential spa systems, making it a direct replacement for worn or damaged pump housings that no longer maintain proper seal integrity.

Built to LX's OEM specifications, this wet end delivers the exact fit you need to restore your spa's circulation system. Bubbles Supply backs every wet end with our 1-year warranty and same-day shipping, so you can get your spa running again without delay. Before installation, verify your existing pump's frame size and connection threading match the 48Y frame and 2" MBT specifications to ensure proper fitment and optimal performance.

Common symptoms this part fixes

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

  • Pump leaking from housing or seal plate
  • Wet end cracked or visibly damaged
  • Loss of prime with no mechanical obstruction
  • Weak or low water flow despite motor running
  • Grinding or cavitation noise from pump housing
  • Seal failure causing water intrusion toward motor

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

Before you buy — quick checklist

  • Confirm your existing pump motor is 48Y frame — check the motor label or measure the bolt pattern
  • Verify your plumbing connections are 2" MBT (male buttress thread) — not all 2" fittings are MBT
  • Confirm your pump's horsepower rating is 1.0 HP before ordering
  • Inspect the motor shaft for damage before reusing it with this new wet end — a scored shaft will destroy the new seal
  • Check whether your pump is single-speed or two-speed, as this does not affect wet end fitment but is useful to document for future reference

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