Why do I need to have my device tested?

Backflow prevention devices are mechanical devices, containing springs and other moving parts that are subject to wearing down and/or breaking. Routine maintenance and testing is necessary to ensure the device is working properly. Depending on the degree of hazard, high health hazard backflow prevention devices need to be tested annually.

  • Annual Testing is required for High Health Hazard devices. These devices are typically used for non-residential purposes, such as hospitals, restaurants, industries, etc. in which there is a high risk of contamination. Residential pools with auto-fill are also required to have a high hazard device and have it tested annually.
