Additional Details

This 2 1/2 inch Ames Series 5000SS reduced pressure detector backflow preventer assembly is designed to protect potable water supplies by preventing backsiphonage and backpressure of hazardous materials, such as fire protection substances and non-potable water, from entering the system.

It features a compact, modular design with a lightweight stainless steel body, an integrated flood sensor, and a GPM metered bypass for leak detection.

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. Before installing, consult your local water authority, building, and plumbing codes.

Flood Sensor Technology

  • Features a flood sensor with SentryPlus Alert® technology to detect continuous discharge from the relief valve.
  • An add-on sensor connection kit is required to activate the flood alert feature.
  • Connection kit options include BMS, cellular communication, and the Sensor Control Monitor for integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.
  • Detects underground leaks and unauthorized water use via the metered bypass.

Construction & Design

  • Stainless steel body provides long-term corrosion resistance and maximum strength, while also reducing installation and shipping costs due to its lightweight nature.
  • Short end-to-end dimensions make retrofit installations easier.
  • Includes domestic outside stem and yoke (OSY) resilient seated gate valves.
  • Thermoplastic cam-check valves feature stainless steel hinge pins, cam arms, and cam bearings, designed for maximum flow at low pressure drop.
  • Stainless steel relief valve with a balanced rolling diaphragm eliminates sliding seals and lowers maintenance costs.
  • Bottom-mounted relief valve design reduces clearance requirements against an outside wall.
  • All internal parts are accessible through a single cover, securely held by a two-bolt grooved coupling.
  • Equipped with four ball type test cocks for easy maintenance.
  • No special tools are required for servicing.

FAQs

What is the primary purpose of the Ames Series 5000SS Reduced Pressure Detector Assembly?

Its primary purpose is to protect drinking water supplies by preventing backsiphonage and backpressure of hazardous materials, such as fire protection substances, into the potable water system.

Can this backflow preventer be used in plumbing systems for human consumption?

No, it is illegal to use this product in any plumbing system providing water for human consumption in the United States, such as drinking or dishwashing. It is designed for non-potable service applications.

What type of connections does this 2 1/2 inch assembly have?

This assembly features a grooved inlet gate connection and a flanged outlet gate connection, along with domestic OSY (Outside Stem and Yoke) resilient seated gate valves.

How does the integrated flood sensor work?

The flood sensor with SentryPlus Alert® technology detects continuous discharge from the relief valve. To activate the alert feature and enable communication, an add-on sensor connection kit is required.

What is the bypass line used for on this backflow preventer?

The bypass line includes a gallons per minute (GPM) meter, which is used to detect underground leaks and unauthorized water use, helping to monitor water consumption.
