Code-Compliant Backflow Installation in Bear, DE

Navigating the plumbing codes for backflow prevention in Bear, DE can be challenging. GNV Plumbing stays up to date with local and state regulations so every installation is fully compliant.

Reduced Pressure Zone Assembly Installation in Bear, DE

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 easily. We carry proven brands like Watts, Febco, Wilkins and Apollo.

Backflow Enclosures and Freeze Protection in Bear, DE

Above-ground assemblies sit in direct sun in summer and can freeze on cold nights. Shutting off and draining outdoor spigots in the fall and insulating crawlspace pipes goes a long way toward preventing winter leaks. We install insulated enclosures, freeze blankets or heated cabinets based on your local climate. Enclosures also discourage theft, since brass backflow assemblies are a common target for scrap thieves. We choose enclosures with enough room for testing and repairs.

Backflow Testing and Certification in Bear

Most water providers require testable backflow assemblies to be certified at installation and then annually. Our certified testers check each valve's opening point, relief valve operation and differential pressure. If a device fails, we can repair or rebuild it on the spot with genuine parts. We submit passing results so you avoid compliance letters or service interruption.

Double Check Valve Assembly Installation in Bear

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.

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