What Is a Backflow Test?

As you know, the team at Backflow Devices Testing & Repair takes water quality very seriously. For us, what we do isn’t just a job; it’s our mission. We try to educate our customers and the public on issues related to backflow prevention. We’ve talked about why backflow testing is important and when you need backflow testing. Today, we’d like to talk about what happens during a backflow test.

Many cities and states require periodic testing of backflow devices. Often, these tests must be passed every one to two years. Your local municipal water system should tell you if you need a backflow device and how often it should be tested. These tests must be conducted by a provider that’s received the proper certifications from your state.

When you hire a company to conduct a backflow test, they’ll come to your home or business to inspect your backflow device. They’ll use the test ports that are built into your device to see if it’s working properly. To do this, all water that’s downstream of the device will need to be shut off. The technicians will then activate the system with a test kit to see if any liquids are passing through the system.

Industry experts estimate that about five percent of devices tested don’t pass. Quite often, worn or broken parts (such as springs, seals, or O-rings) are the cause of the failure. These problems are relatively easy to fix. Prolonged exposure to freezing temperatures may cause more serious problems, like cracked castings. If you suspect a problem with your backflow prevention system, call us immediately to schedule a test. Our service area includes Dalton, Chattanooga, and surrounding areas of Georgia and Tennessee.

This entire process only takes about 30 minutes. If your backflow device is installed outside your home or business, you won’t even have to be there when we test.

We hope this helps you better understand the process of backflow testing. We welcome any questions you have about our backflow testing services.
