Signs of a failing backflow preventer include discolored water, strange odors from your tap, a sudden 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.
No, backflow preventer testing and repair must be performed by a licensed and certified backflow prevention assembly tester. Montana uses a statewide plumbing code based on the Uniform Plumbing Code, and plumbers are licensed by the state. Improper handling can lead to dangerous water contamination.
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.
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.
