Common symptoms this part fixes

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

  • Cracked or leaking filter canister body
  • Stripped or damaged FPT threads preventing proper seal
  • Broken filter basket allowing debris bypass
  • Failed O-ring seal causing pressure loss
  • Housing unable to hold pressure under normal filtration cycle

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

Before you buy — quick checklist

  • Confirm your existing tank body uses 56Y frame sizing — do not assume based on pump size alone
  • Verify both inlet and outlet connections are 2" FPT — measure threads before ordering
  • Inspect whether the leak or failure is in the tank body itself versus the lid, unions, or plumbing fittings
  • Confirm this is the complete body assembly you need — check whether your current setup uses a separate basket or lid
  • Check that your plumbing can accommodate a direct FPT connection or that you have the appropriate adapters on hand

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