Backflow is a term that refers to the unintended flow of water in the opposite direction through your home’s plumbing system.

Common causes are back pressure, back siphonage, and damage on sewage pipes.

Without adequate precautions, the dangers of backflow can pose a serious threat to public health.

There are numerous documented instances of contaminants contaminating public drinking water as a result of cross connection/backflow issues, resulting in illness, disease, and even death.

Backflow can occur at any property with a water supply connection under the right circumstances. If your property is classified as a high or medium hazard risk and you do not have a backflow prevention device installed, it is possible for your property to contaminate the drinking water supply.

After installation, there is a test that is needed to be done. Backflow testing typically takes between 20 and 30 minutes to complete, assuming no repairs or adjustments are required.
