Frequently Asked Questions About Backflow Preventer in Rockville
Annual residential backflow testing typically costs $75 to $150 per assembly. Repairs with a rebuild kit usually run $150 to $450. New residential installation ranges from $300 to $1,200, and commercial RPZ assemblies often cost $1,500 to $5,000 installed.
BVL Plumbing stands behind our work with a comprehensive warranty on parts and labor for all backflow preventer services. The warranty period will be outlined in your service agreement, but generally, new installations come with a manufacturer's warranty on the device and our warranty on the labor.
Most water providers require testing at least once per year. Some require testing after installation, repair or relocation as well. Your provider's notice will list the deadline.
If your backflow preventer fails its annual test, you will usually receive a notice from the Rockville 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.
No, backflow preventer testing and repair must be performed by a licensed and certified backflow prevention assembly tester. Plumbing work in Maryland must be done by state-licensed plumbers, and the state licensing board takes unlicensed work seriously. Improper handling can lead to dangerous water contamination.
An RPZ, or Reduced Pressure Zone assembly, offers the highest level of protection, suitable for high-hazard cross-connections. A DCVA, or Double Check Valve Assembly, provides moderate protection and is usually used for low to medium hazard situations, like irrigation systems. The choice depends on the application and local code rules.
The lifespan of a backflow preventer typically ranges from 10 to 20 years, depending on the type, manufacturer, water quality, and maintenance. Regular testing and timely repairs can extend its life. However, certain components like rubber seals may need replacement sooner due to normal wear.
Most municipalities and water utilities require backflow preventers to be tested every year. This confirms the device is working correctly to protect the public water supply from contamination. We can help you schedule these regular inspections.
