Header damage can create pressure loss, external leaks, and poor water flow through the heater.\u003c\/p\u003e\u003cp\u003eThis return header collects heated water as it leaves the exchanger and directs it back into the plumbing path on compatible 181 to 402 8-tube heaters. When the header cracks, corrodes, or no longer seals properly, the heater can leak and lose water-side stability. Replacing it restores the return-side water routing assembly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWater leak develops at the return side of the heater\u003c\/li\u003e\n\u003cli\u003eHeader shows corrosion, cracking, or worn sealing surfaces\u003c\/li\u003e\n\u003cli\u003ePressure loss appears around the exchanger outlet area\u003c\/li\u003e\n\u003cli\u003eNeed to fix a Raypak heater with return-side header failure\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat this part does:\u003c\/strong\u003e It routes heated water out of the exchanger and back into the plumbing system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for Raypak 181 to 402 8-tube heaters.
