About Backflow Prevention

The objection of backflow prevention is to protect our drinking water from contamination. Water lines are designed to structurally produce pressure to move water to the desired location. Any time there is a reduction in pressure, a backflow incident can occur. Backflow prevention devices are installed at the cross connection of lines to eliminate backflow incidents. These devices need to be tested annually to ensure that they function as designed. There are different classifications and grades of backflow prevention devices. Backflow prevention devices have commercial and residential applications. The EPA and State Law requires annual testing and maintenance of these backflow devices as a preventative measure. Your local water purveyor relies on approved and certified backflow prevention assemblies to protect the public water system. These approved assemblies are manufactured with isolation valves and test cocks to permit field testing to demonstrate that the assemblies are properly functioning to prevent a backflow incident. The state law requires all backflow prevention devices be certified and inspected annually by licensed backflow professionals. Certified backflow professionals are required to have constant and updated training and certifications. All testing equipment is evaluated for performance, pressure tested, and checked for accuracy annually.
