Flow sensors detect water movement through a heater or hydronic system and signal the control board to enable burner or heating element operation. Without a functioning flow sensor, the system cannot confirm water circulation, which prevents ignition and protects the heat exchanger from dry-fire damage. This kit is intended for service and replacement work performed by licensed pool and spa technicians or qualified HVAC and hydronic heating professionals.\u003c\/p\u003e\u003cp\u003eThis flow sensor kit is suited for service applications on pool heaters, spa heaters, and hydronic heating equipment that use 2-inch NTP pipe fittings. It is a direct service replacement intended to restore proper flow-detection function to an existing system. Technicians typically install this kit when diagnosing flow-related fault codes or when a failed sensor is confirmed as the root cause of ignition lockout or circulation errors.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-inch NTP connection for integration into standard pipe configurations\u003c\/li\u003e\n\u003cli\u003eService kit format includes components needed for field replacement\u003c\/li\u003e\n\u003cli\u003eEnables control board to confirm active water flow before burner operation\u003c\/li\u003e\n\u003cli\u003eProtects heat exchanger by preventing dry-fire conditions\u003c\/li\u003e\n\u003cli\u003eDesigned for professional service and maintenance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style service replacement flow sensor for pool, spa, and hydronic heating equipment using 2-inch NTP pipe connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed pool and spa technician or qualified heating professional. Shut off the heater and close the supply and return valves before removing the existing sensor. Ensure the pipe threads are clean and use appropriate thread sealant rated for potable or pool water systems as required by local code. Restore water flow and check for leaks before returning the system to operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 2-inch NTP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Type\u003c\/strong\u003e: Service Replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RAYPAK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100-10001058\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RAYPAK","offers":[{"title":"Default Title","offer_id":51619818963250,"sku":"100-10001058","price":146.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ceb5b187737929b5009aa36f8247402.webp?v=1787334946","url":"https:\/\/voomisupply.com\/products\/raypak-100-10001058-flow-sensor-2-ntp-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
