Why am I required to test my backflow prevention assembly annually?

The Safe Drinking Water Act Amendments of 1986, and regulations of most states, state that the water purveyor has the primary responsibility of preventing water from unapproved sources, or any other substances, from entering the public potable water system. The health agency has the overall responsibility for preventing water from unapproved sources to enter either the potable water system within the water consumer’s premises or the public water supply directly. Kitsap Public Utility District operates and maintains a cross connection control program, in accordance with the Department of Health requirements per Washington Administrative Code (WAC) 246-290-490 which states,

"Purveyors have the responsibility to protect the public water systems from contamination due to cross connection. Cross connections which can be eliminated shall be eliminated. The Purveyors shall work cooperatively with the local authorities to eliminate or control potential cross connections."

In accordance with WAC 246-290-490, Kitsap PUD requires all backflow prevention assemblies will be tested upon installation, repair, or relocation and annually by a certified Backflow Assembly Tester (BAT). All tests must be completed annually to avoid potential termination of service.
