What is a backflow preventer?

A backflow preventer or a cross connection device is a mechanism to prevent backflow of contaminated or polluted water into the homeowner’s or public’s drinking water supply. The basic mechanism for preventing backflow is a mechanical backflow preventer, which provides a physical barrier to the backflow of water.

Utility Department Requirements

Local utility departments must comply with the rules and requirements set forth by the Tennessee Department of Environment and Conservation, Division of Water Supply, which requires all water purveyors to provide the safest water possible.  Consequently, every backflow must be tested annually. Many local utility departments require that the property owner have the fireline tested by an independent company.  Jarrett Fire Protection has certified backflow specialists that are able to test the fireline backflows annually and submit the reports to the local utility department.  We are also able to repair domestic, irrigation and fireline backflows.

Metro Water Department inspects all backflows within their division.  However, when that backflow fails, it is up to the property owner to have the backflow repaired within a specified time frame which can be 10 days for a serious offense to 30 days for something less serious.  We are able to test and repair for any utility company within the Middle Tennessee and Huntsville areas.

Jarrett Fire Protection has competitive rates for testing each backflow preventer depending on the size and location of each backflow.
