An RPZ valve, or Reduced Pressure Zone valve, is a crucial component in safeguarding public drinking water and city supplies from cross-contamination. These valves are vital in buildings with irrigation systems, fire suppression systems, or large boilers, preventing the reverse flow of harmful substances like chemicals, stagnant water, and bacteria into the water supply.
In Illinois, the plumbing code requires the use of RPZ valves, a regulation adhered to by all city governments. Moreover, the law mandates annual testing of these devices by a licensed professional. At Green Tech Plumbing, we ensure not only the proper functioning of your RPZ valve but also take care of all subsequent paperwork, submitting it to the city authorities on your behalf. Let us help you stay compliant and safe with our expert backflow prevention services.
