JXi Bypass Kit for Models 200/260/400 (R0589800)
The Jandy R0589800 bypass kit for JXi heaters regulates water flow through the heat exchanger to prevent damage from excessive pressure or flow rates. A simple, affordable replacement that fits JXi 200, 260, and 400 models.
Flow Regulation for Your Jandy JXi Heater
The Jandy R0589800 Bypass Kit is an OEM replacement component designed for the JXi series gas-fired pool and spa heaters. The bypass assembly regulates water flow through the heat exchanger by diverting excess flow around the exchanger when system pressure exceeds optimal levels. This protects the heat exchanger from erosion damage and ensures the heater operates at peak efficiency regardless of pump speed or plumbing configuration.
Key Features
- Flow Regulation: Automatically diverts excess water flow around the heat exchanger to maintain optimal operating conditions
- Heat Exchanger Protection: Prevents erosion and damage caused by excessive water velocity through the exchanger tubes
- OEM Quality: Factory-original Jandy part for guaranteed fitment and reliable long-term performance
- Simple Installation: Replaces the existing bypass assembly with basic hand tools
Compatibility
Fits Jandy JXi gas-fired pool and spa heaters in 200, 260, and 400 models. Part number R0589800. Recommended for replacement when the original bypass valve shows signs of wear, sticking, or failure to regulate flow properly.
