Frequently Asked Questions About Backflow Preventer in Bethesda
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.
Backflow prevention is essential 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.
A standard test usually takes 20 to 45 minutes per assembly. Water is briefly shut off during testing. Repairs may add an hour or more.
New installations and replacements often require a plumbing permit and an initial test. Requirements vary by city and water provider. We obtain permits and handle the initial test.
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 typically used for low to medium hazard situations, like irrigation systems. The choice depends on the application and local code requirements.
Signs of a failing backflow preventer include discolored water, strange odors from your tap, a noticeable drop in water pressure, or visible leaks around the device itself. If you notice any of these, contact a professional plumber right away to assess the issue.
If your backflow preventer fails its annual test, you will typically receive a notice from the Bethesda 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.
BVL Plumbing services all major types of backflow preventers, including Reduced Pressure Zone Assemblies, Double Check Valve Assemblies, Pressure Vacuum Breakers, and Atmospheric Vacuum Breakers. We work with popular brands like Watts, Wilkins, Febco, and Conbraco.

A pipe burst at 11 pm and they actually answered. The plumber showed up within the hour, shut everything down, and had us back to normal the next morning. Could not ask for more.
