Backflow Testing: What Every Long Island Homeowner Should Know

Most people don't know what a backflow preventer is until they get a notice saying it's time to have it tested.

That's normal. It's not something you see every day, but it's an important part of an irrigation system.

What Is Backflow Testing?

A backflow preventer keeps water from your sprinkler system from flowing back into your home's drinking water. If there's a sudden drop in water pressure—because of a water main break, nearby construction, or even a fire hydrant being used—the direction of water flow can change. Without a working backflow device, water from your irrigation system could be drawn back into the public water supply.

Why Is Backflow Testing Required?

New York requires many irrigation systems to have a backflow prevention device and why it has to be tested every year by a certified tester.

How Often Should a Backflow Preventer Be Tested?

The test itself doesn't take long. We're checking to make sure the valves inside the device are still doing what they're supposed to do. Like anything mechanical, they wear over time. You don't want to find out there's a problem when the device is actually needed.

How Do You Know If Your Backflow Preventer Is Working?

Homeowners sometimes ask if they can tell whether the backflow preventer is working just by looking at it. The answer is no. It may look perfectly fine from the outside, but only a proper test will tell you whether it's protecting your water supply the way it should.

For us, it's just another part of taking care of an irrigation system properly.

Why We Include Backflow Testing as Part of System Maintenance

People often think of irrigation as sprinkler heads and a controller on the wall. Those are the parts you notice. But there are a lot of components working together behind the scenes. If one of them isn't doing its job, the whole system isn't being maintained the way it should be.

That's why we include backflow testing as part of our ongoing maintenance. We handle the testing, complete the required paperwork, and make sure your system stays in compliance. It's one less thing for you to keep track of.

After more than 50 years working on irrigation systems across Long Island, I've learned that good maintenance isn't just about fixing what's broken. It's about paying attention to the things that prevent problems in the first place.

Backflow testing falls into that category. It's a simple annual service that protects your home's water supply, keeps your irrigation system compliant, and gives you one less thing to worry about.

That's the way we believe an irrigation system should be maintained.
