Backflow Testing & Prevention

“Backflow” is a term used to describe the phenomenon of water flowing backward through your plumbing system, usually caused by a sudden and drastic change in pressure pushing the water backward (backpressure) or pulling it back into the main supply (backsiphonage). This can cause your building to suddenly and unexpectedly lose your water connection and could potentially risk contaminating your potable water supply or even your building’s main water supply line. For all these reasons, all commercial buildings are required to have backflow prevention devices and are required to have these devices regularly tested.

Have you had your backflow prevention device checked recently? Is your system working properly? Do you need to have your system fixed?

When do I Need a Backflow Test?

The state of Tennessee requires that all backflow devices are tested for functionality every single year. These annual inspections ensure that your backflow prevention device conforms with local and state-wide building standards, as well as ensuring proper functionality. Getting a test is critically important for you, your business, and your community, because even a small amount of cross-contamination between potentially harmful substances and potable water could jeopardize our entire water system.

These systems are known examples of backflow contamination:

  • Irrigation Systems (Lawn Sprinklers, Drip Systems, etc.)
  • Fire Sprinklers
  • Water Treatment Systems
  • Sewage Treatment Systems

What Does Backflow Prevention
Device Testing Entail?

A backflow test consists of a licensed professional checking your system to determine what type of backflow prevention you have and then conducting a test to ensure that the prevention system engages correctly in the event of a change in water pressure. You likely will not be able to use your water or sewage lines while the test is being conducted, but the average test is usually fairly quick, which means you won’t be without your water supply for too long.
