No, backflow preventer testing and repair must be performed by a licensed and certified backflow prevention assembly tester. Water heater replacements, repipes, sewer line work, and adding fixtures typically require a permit and an inspection by the local authority. Improper handling can lead to serious water contamination.
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. Frozen pipes are a real winter risk in Illinois, especially in exterior walls, unheated garages, and crawlspaces during deep cold snaps. Regular testing and maintenance help lengthen 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 promptly.
HVM 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.
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.
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 routine inspections.
