Raypak Pool Flow Switches

Overview

The RAYPAK 100-10001058 is a flow sensor service kit designed for 2-inch NTP (National Tapered Pipe) connections. 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. This 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. Key Features 2-inch NTP connection for integration into standard pipe configurations Service kit format includes components needed for field replacement Enables control board to confirm active water flow before burner operation Protects heat exchanger by preventing dry-fire conditions Designed for professional service and maintenance applications Compatibility Designed as an OEM-style service replacement flow sensor for pool, spa, and hydronic heating equipment using 2-inch NTP…
