Zodiac R0457001 Pressure Switch with Siphon Loop Kit
Restore safe, reliable flow sensing in your JXi heater with the Jandy JXi Water Pressure Switch Kit, R0457001. This genuine Zodiac/Jandy kit monitors water pressure in the heater and enables or disables firing so the unit only runs when proper circulation is present.
Product Overview
The R0457001 kit is a factory replacement pressure switch with siphon loop designed for Jandy JXi gas heaters in the 200, 260, and 400 size ranges. Installed in the heater’s plumbing manifold, it detects adequate water pressure/flow; when flow drops below the set threshold, the switch opens and prevents the burner from operating, protecting the heat exchanger from overheating or damage.
