Frequently Asked Questions About Backflow Preventer in Ellicott City
The cost for backflow preventer services in Ellicott City, MD varies. A standard backflow test usually ranges from $75 to $150. Repairs can cost between $200 and $600, depending on the parts needed, while new installations might range from $450 to $1,500 or more for larger commercial units.

We service all major brands of backflow preventers, including Watts, Wilkins, Febco, Conbraco and Apollo, and Zurn. Our technicians are trained and equipped to handle various models and types, so your device receives expert attention and the right parts for repair.
A well-maintained backflow preventer can last 10 to 20 years or more. However, factors like water quality, exposure to weather, and the type of device can affect its lifespan. Disconnecting garden hoses and shutting off outdoor spigots before the first hard freeze prevents many burst-pipe calls each winter. Regular testing and maintenance help extend its service life.
If your backflow preventer fails its annual test, you will usually receive a notice from the Ellicott City water department requiring prompt repair or replacement. Our technicians can diagnose the failure, perform the needed repairs, and retest the device so it passes inspection and avoids any service interruptions or penalties.
Backflow prevention is crucial because of changing water pressures, main breaks and fire flow that can drop pressure suddenly, and the potential for cross-connections from irrigation systems or industrial processes. These factors increase the risk of contaminated water entering the public supply, making a working backflow preventer essential.
