Connections & Activation

  • This assembly features domestic outside stem and yoke (OSY) resilient seated gate valves.
  • The integrated flood sensor requires an add-on connection kit (sold separately) for active monitoring and alert functionality.
  • Connection kit options include interfaces for BMS (Building Management Systems), cellular communication, RS-485 Modbus, or the Nexa® platform via Wi-Fi. Without a connection kit, the sensor is passive.
  • Flange dimensions are in accordance with AWWA Class D.

Additional Details

This 2 1/2 inch Ames Series 5000SS Reduced Pressure Detector Backflow Preventer Assembly is designed to prevent the reverse flow of hazardous materials and fire protection substances into potable water supplies. It is ideal for non-potable service applications such as irrigation, fireline, and industrial processing where health hazard protection is required.

WARNING: 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. Always consult your local water authority, building, and plumbing codes before installation.

Construction & Design

  • Features a compact, modular design with short lay length for easy retrofit.
  • The main valve body is constructed from 300 Series stainless steel for superior corrosion resistance and strength.
  • Equipped with domestic outside stem and yoke (OSY) resilient seated gate valves.
  • Thermoplastic cam-check valves with stainless steel hinge pins are designed for maximum flow at low pressure drop.
  • A corrosion-resistant stainless steel bottom-mounted relief valve utilizes a balanced rolling diaphragm to reduce maintenance costs.
  • No special tools are required for servicing.

Flood Detection & Monitoring

  • Includes a flood sensor with SentryPlus Alert® technology to detect continuous or excessive water discharges from the relief valve.
  • The flood sensor relays a signal to trigger notification for corrective action, limiting flooding and costly damage.
  • Requires an add-on sensor connection kit (sold separately) for activation, compatible with BMS, cellular communication, RS-485 Modbus, or the Nexa® platform via Wi-Fi.

Bypass & Leak Detection

  • Features a gallons per minute (GPM) metered bypass line to detect underground leaks and unauthorized water use.

FAQs

What is the primary purpose of the Ames Series 5000SS backflow preventer?

The primary purpose is to protect potable drinking water supplies from contamination by preventing the reverse flow of hazardous materials due to backsiphonage or backpressure in non-potable applications like fireline, irrigation, or industrial processing.

Is this backflow preventer suitable for drinking water systems in the United States?

No, 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. It is intended for non-potable applications.

How does the flood sensor feature work, and what is required to activate it?

The flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve. To activate its alert functionality, an add-on sensor connection kit (sold separately) is required, which enables communication with BMS, cellular networks, RS-485 Modbus, or the Nexa® platform via Wi-Fi.

What materials are used in the construction of the Series 5000SS?

The main valve body and all internal metal parts are constructed from 300 Series stainless steel for corrosion resistance. The check assemblies are made from Noryl®, and the relief valve is also stainless steel with a balanced rolling diaphragm.

What is the maximum operating pressure and temperature range for this assembly?

This backflow preventer has a maximum working pressure of 175 psi (12.1 bar). The operational temperature range is 33°F to 110°F (0.5°C to 43°C).
