Reduced Pressure Zone Assemblies (RPZ)

Guarantee the safety and integrity of your property's water supply with our advanced Reduced Pressure Zone (RPZ) assemblies for sprinkler systems. Tailored specifically for commercial property owners, facility managers, and contractors, our RPZ solutions offer unparalleled protection against pollutants and toxins, ensuring that your property is safeguarded from the backflow of contaminated water. Stitching an RPZ assembly into a sprinkler system not only provides peace of mind but also ensures compliance with water safety regulations, making it an essential component for any responsible property management.

How Does an RPZ Work?

A Reduced Pressure Zone (RPZ) Assembly uses a combination of check valves and relief valves to prevent backflow in an irrigation system. These allow water to flow in only one direction: from the potable water supply to the system. If backpressure occurs, the first check valve closes, preventing contaminated water from flowing back into the potable supply. If the first check valve leaks, then a relief valve opens up to release water and ensure contaminants don’t reach the supply line.

RPZ Valve FAQs

Why is an RPZ required for sprinkler systems?

Backflows are necessary to protect your potable water. Sprinkler systems often contain contaminants like fertilizers, pesticides, or stagnant water. An RPZ prevents these substances from entering the drinking water supply due to backpressure or backsiphonage.

What is the difference between an RPZ and other backflow preventers?

RPZ Assemblies offer the highest level of protection against backpressure, and are suitable for systems with health hazard risks. Double Check Valves provide moderate protection and are used for low- to medium-risk systems. Finally, Atmospheric or Pressure Vacuum Breakers protect against backsiphonage only and are used in simpler systems without high risks.

Where should an RPZ assembly be installed?

An RPZ should be installed upstream of the sprinkler system, between the system and the potable water supply. Try to choose a location that is accessible for maintenance and testing. Install the RPZ valve above ground, and in a weather-protected area to prevent freezing.
