Double Check Valve Assembly Installation in Largo
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 allow. We size them to avoid too much pressure loss on your system.

We handle all required permits and inspections.

Above-ground installs are set at least 12 inches above the highest sprinkler head when a PVB is used.
