Backflow is defined as the unintentional reversal of the normal direction of flow in a potable water system that may result in the pollution or contamination of the system by a liquid, gas, solid or mixture. Simply put, backflow is anywhere "bad water" has the chance to mix with "good water."
A Backflow preventer is a mechanical device, and like any mechanical device, it will fail. The plumbing code specifies that every backflow prevention device must be tested at least yearly to verify its operation. Failure to do so could allow a backflow event to harm people and/or property. The commercial backflow test is fairly simple. Every testable backflow device has test ports built into it to allow yearly testing. A backflow technician will connect a test kit to the device and verify proper operation. All water downstream of the backflow device must be shut off to perform the test. Per New Jersey laws, all commercial properties are to have all backflow devices inspected every year. Garden Irrigation is certified to perform this service. We will help the owner or property manager with any permits or paperwork that may be required. NJ DEP requires the installation and testing of backflow prevention systems installed or water supply lines to protect the public from contamination by an unapproved water supply.
