Additional Details

This Colt™ 4 inch stainless steel reduced pressure zone (RPZ) backflow preventer assembly provides critical protection to potable water systems. It prevents the reverse flow of fire protection substances and non-potable water into the drinking water supply, safeguarding against backsiphonage and backpressure in continuous pressure piping applications and health hazard cross-connections.

The assembly features a flood sensor with SentryPlus Alert® technology, designed to detect excessive water discharges from the relief valve. When paired with an optional add-on connection kit, the sensor activates to relay multichannel alerts (call, email, text) to notify personnel about potential flooding events.

Features

  • Lead Free* construction to comply with lead-free installation requirements
  • Extremely compact design, 70% lighter than traditional designs
  • Type 304 (Schedule 40) stainless steel housing and sleeve for durability
  • Groove fittings for integral pipeline adjustment and ease of installation
  • Patented link check modules for lowest pressure loss and unmatched ease of serviceability
  • Domestic outside stem and yoke (OSY) resilient seated gate valves for drip-tight shutoff
  • Includes an integrated supervisory switch as an option on each gate valve of the OS&Y model
  • Configurable for horizontal N-pattern installation
  • Reversible elastomer check discs (silicone or EPDM)
  • Sensor on relief valve for flood detection with SentryPlus Alert® technology
An add-on connection kit is required to activate the flood sensor's communication features. Without the kit, the sensor is passive and will not communicate with other devices.
