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 a must.
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.
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 wear and tear.
