Who Do You Call to Have a Backflow Test Done on Your Sprinklers?

Irrigation backflow preventers are a critical part of your sprinkler system because they prevent contaminated water from infiltrating clean drinking water sources. If you’re having issues with this sprinkler part, knowing who to call to have a backflow test done on your sprinklers is essential.

Since they perform such an important function, most cities and states require backflow devices to be tested on a regular basis—sometimes as often as once a year—by certified sprinkler repair professionals. Backflow testing can’t be DIYed by people who don’t have the proper certifications and licensure from their state. Let’s review the best type of professional to hire for this lawn irrigation service.

Benefits of Hiring a Professional to Do Your Backflow Test

Hiring a sprinkler repair professional to perform the testing on your irrigation’s backflow preventers is mandatory. 

In order to certify to the city government that your backflow preventers are in good working order, the professional who performs the test must have special training in backflow assembly testing. In some states, they may also need to be a licensed contractor to get that training in the first place.

Depending on where you live, these backflow tests may be required yearly or every two to three years to keep your drainage system in working order. Check with your local government to learn more about the specific requirements in your area.

Can I DIY a Sprinkler Backflow Test?

Unfortunately, people who are not trained professionals can’t perform their own sprinkler backflow tests. If you happen to be a licensed contractor, you may be able to take the course required to perform a backflow test—but for most homeowners, this is a job that has to be left up to the pros.

Can I Hire a Plumber to Do the Backflow Test?

Some plumbers perform irrigation backflow prevention tests, but it depends on what kind of training and certifications they have. Some companies specialize specifically in backflow prevention testing. Their whole business model simply relies on these tests. But if you have a plumber you know and trust, it could be worth reaching out to see if they can perform your backflow tests for you.

Certain local sprinkler repair companies may also have certified professionals on staff who can perform these tests. 

How Do Professionals Do Sprinkler Backflow Tests?

During the backflow test, your water will temporarily be shut off—but don’t worry, the test only takes about 20 or 30 minutes to complete.

Backflow testers use specialized, state-approved tools and gauges to measure your system’s water pressure calibration. (After all, backflow only happens if the pressure of the contaminated water outstrips the pressure of the drinking water source—so measuring pressure is the name of the game.) The backflow testers will open and close the various valves in your plumbing setup to make sure everything is working properly. If it is, they’ll certify your device, report as much to the state, and turn your water back on.
