Reduced Pressure Zone (RPZ) Device Installation in Mililani Town, HI
For high-hazard applications in Mililani Town, HI where toxic substances could contaminate the water supply, a reduced pressure zone, or RPZ, device is often required. RPZ backflow preventers offer the highest level of protection, using a relief valve to discharge water if the pressure drops.

Proper installation is critical for effective operation.
Understanding Backflow Preventer Installation Costs in Mililani Town, HI

Double Check Valve Assembly Installation in Mililani Town
Double check assemblies are used for low hazard connections such as many fire sprinkler systems and some irrigation lines. They have two spring-loaded check valves and test cocks for annual certification. Unlike an RPZ, they do not discharge water, so they can be installed in vaults or below grade where local rules permit. We size them to avoid too much pressure loss on your system.
Reduced Pressure Zone Assembly Installation in Mililani Town, HI
RPZ assemblies offer the highest level of protection and are required for high hazard connections like commercial kitchens, medical facilities, chemical injection and car washes. They include two independent check valves with a relief valve that dumps water if either check fails. Because the relief valve can discharge, we plan for drainage and install the assembly above grade where it can be tested. We carry proven brands like Watts, Febco, Wilkins and Apollo.
