Before you buy — quick checklist

Confirm your spa runs on 230V — do not install this on a 115V system
Verify your existing plumbing uses 1-inch barb connections
Check the label on your old pump and confirm it is a Grundfos 43 Series
Note whether your spa controller expects a specific amp draw — this unit pulls 0.35A
Confirm this is your circ pump and not a therapy or jet pump — circ pumps run continuously at low flow

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