It is the genuine Raypak part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a return header is\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA heat exchanger has a header at each end. Water enters at one, runs through the tube bundle where the burner heats it, and turns at the return header on its way back to the pool. The header takes the full flow and the full temperature swing of every heating cycle.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy they fail\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eHeaders crack, corrode or distort with age, hard water and repeated heating and cooling. The symptom is water at the end of the heat exchanger. There is no repair for a failed header; it is changed as a unit, and this listing is the polymer version Raypak fits to the 206A through 406A heaters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eConfirm the model on the heater rating plate.
