Double Check Valve Assembly Installation in Grand Forks
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.

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

We install Watts, Febco, Wilkins by Zurn and Apollo assemblies. Each has readily available repair kits, which keeps future service affordable.
An RPZ, or reduced pressure zone device, provides the highest level of protection and is used for high-hazard applications where contaminants could be toxic. A DCVA, or double check valve assembly, is used for low-hazard applications where contaminants are non-toxic. The choice comes down to the risk of contamination at the cross-connection point.
Constant dripping or discharge from an RPZ relief valve, low pressure downstream and a failed annual test are common signs. Visible corrosion or a cracked body from freezing also means service is needed.
We install all common types of backflow preventers, including reduced pressure zone assemblies, pressure vacuum breakers and double check valve assemblies. Our team will recommend the right device based on your property's hazard level and local plumbing codes in Grand Forks.
In Grand Forks, most backflow preventers must be tested annually by a certified backflow tester to confirm they are working correctly and providing adequate protection. This is a separate service from installation but is essential for ongoing compliance and safety.
