Description

Overview

The Ames Colt LFC500 6-inch reduced-pressure detector assembly protects the upstream water supply against backsiphonage and backpressure in health-hazard applications. Two independent check modules and an intermediate pressure-differential relief valve provide backflow protection; a metered bypass registers leakage or unauthorized water use from the fire-protection line. This listing identifies OS&Y shutoff valves.

When installed on an automatic sprinkler supply, NFPA 13 addresses installation and testing provisions for a required backflow assembly, and NFPA 25 addresses ongoing inspection, testing and maintenance, including applicable forward-flow testing. The water authority determines the need and acceptable protection type; the assembly does not by itself establish system compliance.

Key Features & Construction

  • Type 304 Schedule 40 stainless-steel housing and sleeve with accessible check modules.
  • Maximum working pressure of 175 psi and water temperature range of 33°F to 110°F.
  • Metered bypass registers gallons or cubic measurements; confirm the supplied meter units.
  • OS&Y shutoffs provide isolation. Integrated supervisory switches are optional, not established as included by the store SKU.
  • The 2025 family sheet describes a relief-valve flood sensor. An add-on connection kit is required for communication; confirm the supplied revision and accessories. A sensor does not replace required drainage.
  • Lead-free construction refers to the manufacturer’s wetted-surface lead-content criterion, not construction entirely without lead.
