Backflow Testing

What is a backflow?

Backflow refers to the reverse flow of non-potable water, or other substances, through a cross-connection and into the piping of a public water system or customer’s potable water system. Two types of backflow are backpressure backflow and back-siphonage.

Water in our water supply system is normally maintained at a specific pressure, one that allows us to have water flowing from our taps, showers and into our toilets' tank. Occasionally, however, there is a fault.

If a pipe freezes, bursts, or leaks there is the chance that the pressure in the system can be reduced, and as a result, contaminated water from other sources can enter the system. This can be from groundwater or from other areas where water is stored.

To stop this from happening, as it can be dangerous, backflow prevention devices need to be in place. In fact, this is a regulatory requirement for some systems and it must be certified annually by a backflow prevention specialist.

Like car parts, backflow preventers wear out over time, which is why it's important to have them tested regularly. Certified backflow testing experts can make sure all your backflow devices are working and safe.

We all assume that our water supply is safe and drinkable, but contaminated drinking water is responsible for hundreds of deaths every year in this country. For more information, contact the City of Corinth Building Official Cleve Joiner at (940) 498-3270.

Protect Your Environment

In order to ensure the proper operation of a backflow prevention assembly, it must be tested and certified upon installation and at least once a year thereafter by a licensed backflow tester.
