Backflow prevention devices such as double check valves, vacuum breakers and reduced pressure backflow devices are commonly used in our area to protect both domestic wells and municipal water systems from back syphon and back flow cross contamination.
These devices protect cross contamination from syphoning from ponds or swimming pools filled by a hose or lawn contaminants such as fecal matter from the lawn back flowing from a loss of pressure in the pressure tank on a domestic well, or loss of pressure on a municipal system.
These devices by state and federal law are required to be tested annually. See attached information. We can perform this test as part of your overall maintenance program. Backflow Idaho State Law
