The Watts LFRK 909-CK1 First Check Kit provides genuine OEM replacement internal components for Watts Series 909 and LF909 reduced pressure zone backflow preventer assemblies. Designed for installation within commercial wet pipe fire sprinkler systems, domestic water supplies, and isolation assemblies, this kit restores proper check valve seating and prevents reverse flow under backpressure or backsiphonage conditions.

In compliance with NFPA 13 and NFPA 25 requirements for the inspection, testing, and maintenance of water-based fire protection systems, backflow assemblies must undergo periodic operational testing and internal component servicing. Utilizing original factory replacement parts preserves the assembly's certified hydraulic ratings and ensures dependable operation during a backflow event.

  • Factory original replacement components ensure exact fit and seamless integration with existing valve bodies.
  • Constructed from high-quality, lead-free materials meeting stringent environmental and plumbing standards.
  • Engineered specifically for routine maintenance and overhauls without requiring specialized field service tools.
  • Available in size-specific configurations to support 2½-to-3-inch and 4-inch backflow preventer assemblies.
