REPLACEMENT PART PRE-CHECK
Check the fit.
Before you buy.
Three free, source-backed tools: compare a replacement pool pump motor's nameplate field by field, pick the right well pump pressure-switch range, or find the official replacement for a discontinued furnace control board — before the order ships, not after.
POOL PUMP MOTORS
Nameplate pre-check
Enter your existing motor's nameplate and the seller's spec for the one you're about to buy. You get a field-by-field verdict — same, different, or verify — plus the official alias group your model belongs to.
WELL PRESSURE SWITCHES
30/50 or 40/60?
Answer three questions — house height, plumbing age, tank status — and get a sourced starting recommendation for your switch range, or a plain "consult a professional" when the answer genuinely depends on your site.
HVAC CONTROL BOARDS
Furnace board lookup
Look up the part number stamped on your dead furnace control board and find the official universal replacement it cross-references to — from ICM Controls and White-Rodgers manufacturer documents, not a guess.
