Before you buy — quick checklist

Confirm your existing pump label reads 115V — do not install on a 240V circuit
Match horsepower: verify old pump is 0.5 HP, not 0.75 or 1.0 HP
Check discharge orientation on your current pump (front vs. top) against your plumbing layout
Note union size on existing plumbing fittings before ordering to confirm compatibility
Verify this is a single-speed application — this pump does not support two-speed wiring

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