Connections

  • The main assembly features grooved couplings for easy installation into compatible piping systems.
  • The flood sensor requires an add-on sensor connection kit to activate its alert features. This kit enables communication with Building Management Systems (BMS) and cellular networks, or integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.

Application

  • This assembly is suitable for non-potable service applications such as irrigation, fireline, or industrial processing to prevent backflow into drinking water supplies.

Additional Details

This 4 inch Ames Series 5000SS Reduced Pressure Detector Backflow Preventer Assembly is designed to prevent the reverse flow of fire protection substances and non-potable water from being pumped or siphoned into the potable water supply. It is suitable for health hazard applications, protecting drinking water supplies from dangerous cross-connections.

It is illegal to use this product in any plumbing system providing water for human consumption, such as drinking or dishwashing, in the United States. Before installing standard material product, consult your local water authority, building and plumbing codes.

Construction & Features

  • Features a short lay length, lightweight stainless steel body for easy installation and reduced shipping costs.
  • Equipped with domestic outside stem and yoke (OSY) resilient seated gate valves and thermoplastic cam-check valves for maximum flow and low pressure drop.
  • A corrosion-resistant stainless steel bottom-mounted relief valve with a balanced rolling diaphragm eliminates sliding seals, reducing maintenance.
  • Includes a gallons per minute (GPM) metered bypass to detect underground leaks and unauthorized water use.
  • Features a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
  • When paired with an add-on connection kit, the sensor is activated to relay alerts for potential flooding events, compatible with BMS, cellular communication, and integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.
  • No special tools are required for servicing, and its compact design allows for smaller enclosures.
  • Short end-to-end dimensions facilitate easy retrofit installations.
