RPZ (Backflow Device)

A Reduced Pressure Zone valve (RPZ) is a device used to protect your drinking water from contamination.  This contamination can come from irrigation systems, pools, spas, fire sprinkler systems and large boilers.  Local municipalities require that RPZ devices be tested and certified annually  to ensure  they are functioning properly.

Mahoney Plumbing’s technicians are licensed and trained to install and test RPZ devices.
