Who is responsible for ensuring backflow prevention devices are tested?

The responsibility for ensuring that backflow prevention devices are tested primarily falls on the property owner, or it may be dictated by local code requirements. Backflow prevention devices are critical components in preventing the reverse flow of contaminated water into the potable water supply. Local codes often specify that property owners must ensure these devices are regularly tested and maintained to ensure their effectiveness.

In many areas, it’s a legal requirement for property owners to have their backflow prevention devices tested annually or according to the guidelines set forth by local water authorities. While various professionals, such as irrigation technicians and plumbers, may perform these tests, the ultimate responsibility lies with the property owner to ensure compliance with local regulations and the safe operation of their water supply system.

While local plumbing inspectors and water service providers have roles in monitoring and enforcing compliance regarding these devices, it is the property owner's responsibility to ensure that testing is completed as required by those regulations.
