What Is Backflow Testing? What Commercial Property Owners Need to Know

It’s common for commercial property owners to receive a notification from their insurance carrier or municipality requiring backflow preventer testing. In simple terms, backflow occurs when contaminated water flows in the wrong direction and has the potential to enter the public water supply. If your building has a fire sprinkler system, Vermont state code requires a backflow preventer to protect public drinking water.

This device must be tested regularly to ensure that it’s functioning correctly. Firetech Sprinkler Corp. has AWWA-certified technicians who can provide backflow testing services throughout Vermont, Northern New Hampshire, and Northeastern New York. This allows commercial property owners to stay compliant and protect public health.

What Is Backflow?

Backflow happens when water flows in the opposite direction of where it’s intended to go. In a fire sprinkler system, water sits inside your pipes under pressure. If system pressure suddenly drops due to a water main break, maintenance work, or even high water demand, water can reverse direction and begin flowing back toward the public water supply.

This reversal in direction is known as backflow, and it can potentially pull the contents of your fire sprinkler piping into the potable water system. Fire sprinkler water may contain rust inhibitors, antifreeze solutions, sediment, and other chemicals that aren’t safe for drinking water. To prevent this risk from happening, fire sprinkler systems are equipped with a backflow preventer. This is a mechanical device that is specifically designed to ensure that water only flows in one direction. This helps protect public health and maintain safety for your municipal water supply.

What Is Backflow Testing?

Backflow testing is an annual inspection of your backflow preventer device to ensure that it’s functioning properly. During the test, a certified technician will temporarily shut off the water supply and use specialized equipment to evaluate the internal check valves and relief valve under pressure. This process confirms that your device can effectively prevent water from flowing in the wrong direction.

Most commercial fire sprinkler systems need backflow testing that takes about 30 to 60 minutes. Once testing is finished, our technician will document the results and submit the required paperwork to your local water authority or Authority Having Jurisdiction (AHJ). This ensures that you meet local fire and building codes for your area.

Who Is Required to Have Backflow Testing Done?

Most commercial property owners are required to have backflow testing performed annually. The Vermont Division of Fire Safety requires businesses that have automatic fire sprinkler systems to regularly test their backflow preventer to protect the public water supply. Both New Hampshire and New York have similar requirements that are enforced through fire codes, state plumbing codes, and local regulations.

Apart from government requirements, many commercial insurance policies also require annual backflow testing. Failure to comply can lead to violations, insurance-related issues, and penalties. Building types that commonly require backflow testing include retail stores, restaurants, multifamily residential properties, office buildings, schools, warehouses, and hotels.

How Often Does Backflow Testing Need to Happen?

For most commercial properties, annual backflow testing is the standard requirement throughout New York, New Hampshire, and Vermont. An annual inspection ensures the backflow preventer is operating correctly and protects the public drinking water supply from unnecessary contamination. In some cases, local water authorities and municipalities may require more frequent testing depending on your property’s specific requirements and hazard classification.

It’s important for property owners to maintain accurate testing records and make them available to the AHJ, insurance carrier, or local water authority upon request. Keeping adequate documentation is a vital part of maintaining compliance. If you’re missing a required test or you allow your certifications to lapse, it can lead to an interruption of your water service, failed inspections, fines, and even issues with your insurance coverage or policy renewal.

What Happens If a Backflow Preventer Fails Testing?

A failed backflow test means that one or more of the components of your backflow preventer are not functioning properly. Because the device can no longer provide reliable protection against reverse water flow, it needs to be repaired. Common causes of failure include debris lodged inside the valve assembly, a malfunctioning relief valve, and worn check valve seats.

Once your backflow preventer is repaired or replaced, it must undergo retesting to receive certification. In most cases, Firetech Sprinkler Corp. can perform the necessary repairs for your backflow preventer to help restore compliance quickly for your business. After the repairs are completed and your backflow preventer is retested, we’ll provide you with new documentation to show proper compliance.

Most municipalities, states, and water authorities require annual testing to be completed by a technician who holds a recognized backflow certification. This means they’re properly trained in testing backflow prevention devices. Firetech Sprinkler Corp. has technicians who are certified by both the American Water Works Association (AWWA) and the New England Water Works Association (NEWWA).
