What Is a Backflow Preventer?

Backflow is the reversal of the flow of a liquid, gas, or suspended solids. A backflow preventer is a mechanical device with check valves, air inlets, and relief valves installed on water piping to prevent pressurized water from flowing back from a sectioned system into the public water supply. Without one, water can flow backward into the piping and contaminate your municipality’s water—which is not something you want to do! Specialized backflow preventer valves are used where the necessary clearance or space isn’t available to install an air gap or when a pressurized operation or other factors rule out the use of an air gap. Areas where water needs to be contained include swimming pools, lawn irrigation, fire sprinkler systems, or industrial centers that use toxins, chemicals, or waste.

At Unifour Fire & Safety, we are experts in testing, maintaining, and installing backflow preventers in North Carolina, South Carolina, and Georgia. Call us at 866-511-5540866-511-5540!

Backflow Preventer Inspection & Testing

A backflow preventer needs to be inspected on a routine basis. This isn’t just a suggestion but a requirement by the National Fire Protection Association (NFPA) and your local municipality. All testers must be licensed and certified through a state-, county-, or city-approved agency.

During this test, water is manipulated through the device to ensure that check valves close and/or relief valves open. Since backflow preventers are mechanical devices with metal, plastic, and rubber parts under constant water pressure, they do have parts that will fail and need replacement or repair. In some cases, full replacement of the device or assembly will be necessary to uphold the integrity of our water supply.

Routine backflow preventer testing is crucial to protect drinking water from becoming contaminated. Our team at Unifour Fire & Safety can install, inspect, or test your backflow preventers in North Carolina, South Carolina, and Georgia—call us today at 866-511-5540866-511-5540!

Backflow Preventer FAQs


How long does a backflow preventer last?

As a general rule, you should expect your backflow preventer to need to be rebuilt or replaced every five years or so, but this can vary significantly depending on the product you have installed, how often you have maintenance performed, what kind of maintenance and testing you have performed, etc.

What should I do if inspection or testing identifies a problem?

Once we’ve identified a problem, we’ll also suggest a solution. Depending on what precisely is wrong with your backflow preventer, this might mean minor servicing adjustments, replacing certain components, or the total replacement of your backflow preventer. In some cases, our inspection and/or testing might suggest a more fundamental problem with how your backflow preventer is installed, and a simple swap to a similar model won’t resolve the issue—we’ll make sure you understand your options and what’s necessary to get things back to normal.

What are the signs of a problem with my backflow preventer?

Problems with a backflow preventer can be almost undetectable without testing or immediately obvious, depending on the problem you’re having and where the backflow preventer is installed. The failure of a backflow device can result in discolored, smelly, or sediment-filled water coming from your taps, it might result in slowed or stopped water flow, or it could affect the way water drains in your home. Remember, contamination of your water—when it’s not mere rust or hard water—should be treated as an emergency and handled immediately.

Should I be performing some sort of maintenance on my backflow preventer?

Unless you have appropriate technical expertise, leave backflow preventer inspections and testing to a professional. This is a device where even minor mistakes could result in the direct contamination of water, with all the risks to health and plumbing that entails. The best thing you can personally do for your backflow preventer is to keep up with its inspections and testing in accordance with best practices or its manufacturer’s standards.
