The three parts that fail first (most-requested)

1. Replacement pump — the most common wear item after 300-500 hours or freeze damage. Check the parts diagram for the exact model.
2. Replacement pressure hose — 3/8" wire-braid hose. Shop Simpson pressure washer hoses →
3. Replacement wand / lance — cracked, bent, or corroded wands are the #1 field-replaceable item after nozzles.
