RPZ Valve applications

RPZ Valve Testing and Installation Services for Fluid Category 4 Applications

An RPZ (Reduced Pressure Zone) valve is a critical component for backflow prevention in fluid category 4 applications. These applications, as defined by the Water Regulations, involve fluids that pose significant health hazards due to high concentrations of toxic substances. This includes fluids containing:

  • Chemical or carcinogenic substances
  • Pesticides (including insecticides and herbicides)
  • Environmental organisms with potential health significance

How RPZ Valves Protect Potable Water in Common Fluid Category 4 Applications:

  • Commercial Dishwashers & Bottle Washing: RPZ valves prevent contaminated water from re-entering the potable water supply, ensuring that chemicals and detergents used in these processes do not compromise drinking water quality.
  • Commercial Heating Systems: These systems often contain antifreeze or other chemicals. An RPZ valve ensures that these substances do not backflow into the potable water system, maintaining safe drinking water.
  • Fire Sprinkler Systems: RPZ valves protect against backflow of antifreeze solutions and other chemicals used in sprinkler systems, safeguarding the potable water supply from contamination.
  • House Mini Irrigation Systems: In irrigation systems without fertilizers or insecticides, RPZ valves prevent any potential contaminants from backflowing into the drinking water, ensuring safe water for household use.
  • Food Preparation, Dairies, & Refrigeration Equipment: RPZ valves prevent contaminants from food processing and refrigeration systems from entering the potable water supply, protecting public health.
  • Dyeing Equipment: In dyeing processes, RPZ valves prevent dyes and chemicals from contaminating the potable water system, ensuring safe drinking water.
  • Car Washing & Degreasing Plants: These facilities use various chemicals and detergents. RPZ valves prevent these substances from entering the potable water supply, maintaining water quality.
  • Commercial Clothes Washing Plants: RPZ valves ensure that detergents and cleaning agents used in laundry facilities do not backflow into the drinking water supply.
  • Brewery & Distillation Plant: RPZ valves protect the potable water supply from contaminants used in brewing and distillation processes, ensuring safe drinking water.
  • Printing & Photographic Equipment: These applications use various chemicals that can be hazardous. RPZ valves prevent these substances from contaminating the potable water system.
  • Water Treatment Plants or Softeners: RPZ valves ensure that substances other than salt used in these processes do not backflow into the potable water supply.
  • Pressurised Fire Fighting Systems: RPZ valves prevent chemicals used in these systems from contaminating the drinking water supply.
