Backflow Assembly Testing
Approving Backflow Assemblies
All assemblies must go through rigid and extensive factory testing through the Foundation for Cross Connection Control and Hydraulic Research (FCCCHR) at the University of Southern California before it is considered to be an approved assembly. All assemblies must be pressure-tested according to their designed operating pressure for use on cold-water service.
The hydrostatic test pressure is twice the maximum rated working pressure of the assembly. The entire assembly is subjected to the hydrostatic test, both in the normal direction of flow and in the reverse direction of flow with the opposite side of the barrier open to the atmosphere. There must be no leakage across any barrier, and the hydrostatic test pressure is maintained for a minimum of 10 minutes for each test. When your assembly has the required annual test, the tester attaches a test gauge to ensure the check valves hold to the proper value.
