Description

The Watts 6 inch Lead Free Reduced Pressure Zone (RPZ) Assembly is engineered to protect potable water supplies from health hazard cross-connections caused by backsiphonage and backpressure. This model features a durable 300 Series stainless steel body with a short lay length, and patented torsion spring check valves for optimal flow. It is configured without shutoff valves and includes an integrated flood sensor with SentryPlus Alert® technology. When activated with an add-on kit, the sensor detects excessive water discharges from the relief valve, preventing potential flooding. Designed for easy maintenance and reliable performance with a maximum operating pressure of 175 PSI.

Flood Sensor Activation & Connectivity

  • This Watts Series 994 RPZ backflow preventer includes an integrated flood sensor with SentryPlus Alert® technology, designed to detect excessive water discharges from the relief valve.
  • To activate the flood alert feature and receive notifications, an add-on sensor connection kit is required. Without this kit, the sensor operates as a passive component and will not communicate with any external devices.
  • The add-on connection kit enables the flood sensor to relay signals for notification to facility personnel, and is compatible with Building Management Systems (BMS) and cellular network communication platforms.
  • Watts recommends installing a drain line and the required 994AGK-P air gap for proper drainage and functionality.

Additional Details

This 6 inch Watts Series 994 Lead Free Reduced Pressure Zone (RPZ) Assembly backflow preventer is designed to protect potable water supplies from health hazard cross-connections caused by backsiphonage and backpressure.

This model is assembled without shutoff valves and features a short lay length, a durable stainless steel body, and includes an integrated flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve, signaling potential flooding.

Features

  • Lead Free construction, ensuring the wetted surfaces contain less than 0.25% lead.
  • Stainless steel body provides long-term corrosion resistance and maximum strength, weighing half that of competitive designs to reduce installation costs.
  • Short end-to-end dimensions make retrofit easy and compact construction allows for smaller enclosures.
  • Patented torsion spring check valves (thermoplastic and stainless steel) provide maximum flow at low pressure drop and trouble-free operation.
  • Bottom mounted stainless steel relief valve features a balanced rolling diaphragm to eliminate sliding seals and lower maintenance costs, reducing clearance requirements when installed against an outside wall.
  • Flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve.
  • Flood alert feature is activated with an add-on sensor connection kit, compatible with BMS and cellular network communication.
  • Maintenance is simplified with no special tools required for servicing and a single access cover for in-line repairs.

FAQs

What is a Reduced Pressure Zone (RPZ) Assembly used for?

A Reduced Pressure Zone (RPZ) Assembly like the Watts Series 994 is designed to protect potable water supplies from contamination. It prevents the reverse flow of hazardous materials into the drinking water system due to backsiphonage or backpressure.

Is this Watts Series 994 RPZ backflow preventer lead-free?

Yes, this Watts Series 994 RPZ backflow preventer is lead-free. The wetted surfaces of the product that contact consumable water contain less than one quarter of one percent (0.25%) of lead by weight.

Does this model of the Watts Series 994 RPZ come with shutoff valves?

No, this specific model (LF option) of the Watts Series 994 Reduced Pressure Zone Assembly is configured and supplied without shutoff valves.

How does the integrated flood sensor work, and what is needed for it to send alerts?

The integrated flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve. To activate the flood alert feature and enable notifications to facility personnel, an add-on sensor connection kit is required. Without this kit, the sensor is passive.

What materials are primarily used in the construction of this backflow preventer?

The main valve body and all internal metal parts are constructed from 300 Series stainless steel for corrosion resistance and strength. The check assembly specifically uses Noryl® material.
