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.
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.
We service Watts, Febco, Zurn Wilkins, Apollo and other common brands. Our trucks carry rebuild kits for common models. Less common parts can usually be ordered fast.

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. Mountain and high desert communities in Southern California do get hard freezes, so pipes there need insulation and careful winter care. Regular testing and maintenance help extend its service life.
The lifespan of a backflow preventer usually 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 normal wear.
