Raypak 006718F – Bypass Spring – RP2100 Ctherm PlasticIf your heater is running hot internally, short cycling, or showing signs of unstable water flow through the header area, the bypass assembly is worth checking. 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.This 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.
