About this wet end

This Aqua-Flo by Gecko 48Y frame wet end delivers reliable replacement performance for spas equipped with 1.0HP main pumps requiring 1-1/2" MBT connections. The 48Y frame configuration ensures proper alignment with your existing motor assembly, while the dual 1-1/2" male buttress thread fittings provide secure plumbing connections that won't leak under pressure.

Built to OEM specifications, this genuine Aqua-Flo wet end (part #91040700-000) comes with our exact fit guarantee, ships same-day from our Canadian warehouse, and includes a full 1-year warranty for complete peace of mind. Whether you're dealing with cracked housing, worn impeller chambers, or seal failures, this wet end restores your pump's original performance and efficiency. Verify your existing frame size and thread measurements before installation to ensure proper fitment with your spa's plumbing configuration.

Common symptoms this part fixes

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

  • Cracked or leaking pump housing
  • Low or no water flow from jets
  • Visible impeller wear or damage
  • Pump runs but pressure is weak
  • Wet end seal failure causing water intrusion into motor
  • Grinding or cavitation noise from pump

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

Before you buy — quick checklist

  • Confirm your existing motor is a 48Y frame — check the motor label or measure the face dimensions before ordering
  • Verify your plumbing connections are 1-1/2" MBT (male buttress thread) — not all 1-1/2" fittings are MBT
  • Confirm your existing pump is rated at 1.0 HP — do not mix wet ends and motors of different HP ratings
  • The wet end replaces the pump housing and impeller assembly only — your existing 48Y motor must be reused
  • Inspect the motor shaft seal seat before reassembly — a worn seat will cause the new wet end to leak
  • Check that your spa plumbing supports 1-1/2" connections on both suction and discharge sides

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