A weak or damaged bypass spring can throw off internal flow regulation and make a Raypak heater not working problem look like a pressure issue, a limit issue, or a bad governor.\u003c\/p\u003e\u003cp\u003eThis bypass spring is used in the internal water flow control assembly on RP2100 Ctherm plastic header systems. Its job is to help the bypass mechanism respond correctly so water moves through the heater the way Raypak intended. When the spring weakens, corrodes, or loses tension, flow regulation suffers and heater performance can become inconsistent.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeater shows signs of unstable internal water flow\u003c\/li\u003e\n\u003cli\u003eBypass assembly is weak, stuck, or not responding correctly\u003c\/li\u003e\n\u003cli\u003eShort cycling or overheating symptoms appear during operation\u003c\/li\u003e\n\u003cli\u003eRaypak heater troubleshooting points to bypass assembly wear\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat this part does:\u003c\/strong\u003e It provides the spring tension used by the internal bypass assembly to regulate water flow through the heater.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for Raypak RP2100 Ctherm plastic header systems.
