What Is a Backflow Preventer (RPZ) and Why Is It Important?
A backflow preventer, or Reduced Pressure Zone (RPZ) device, is a vital part of your plumbing system. It protects your drinking water supply from contamination by stopping dirty or hazardous water from flowing back into clean lines. Whether you're a homeowner or a commercial property owner, New York State and Suffolk County plumbing codes often require RPZ devices to ensure public health and safety.
Without proper testing and maintenance, backflow can lead to serious health risks. That’s why annual
RPZ testing by a licensed plumber is not just smart—it’s required.
