Frequently Asked Questions About Backflow Preventer in Kirkland
Annual residential backflow testing usually 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.
Yes, new backflow preventer installations or major replacements often require a plumbing permit from the Kirkland building department. This makes sure the installation meets local codes and is inspected for proper function. FHN Plumbing can help you navigate the permitting process.
FHN 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 leading brands like Watts, Wilkins, Febco, and Conbraco.
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.
Water providers may send follow-up notices, charge fees or eventually suspend service. Scheduling early avoids these problems. We can often fit urgent tests in quickly.
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. Hard freezes are infrequent on the west side of Washington, but short cold snaps catch many homes with uninsulated pipes off guard. Regular testing and maintenance help extend its service life.
Signs of a failing backflow preventer include discolored water, unusual tastes or odors in your water, water leaking from the relief valve, or a sudden drop in water pressure. If you notice any of these issues, it is important to have your device inspected right away.
We service Watts, Febco, Zurn Wilkins, Apollo and other common brands. Our trucks carry rebuild kits for popular models. Less common parts can usually be ordered fast.
