Proper drainage is planned for the relief port discharge.

Frequently Asked Questions About Backflow Preventer in Simi Valley
Backflow preventer testing in Simi Valley, CA typically costs between $75 and $150. This fee covers the technician's visit, the test itself, and the submission of required reports to your local water authority. Complex commercial systems or multiple devices may carry higher costs.

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.
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.
If your backflow preventer fails its annual test, you will typically receive a notice from the Simi Valley water department requiring prompt repair or replacement. Our technicians can diagnose the failure, perform the needed repairs, and retest the device so it passes inspection and avoids any service interruptions or penalties.

Yes, new backflow preventer installations or significant replacements often require a plumbing permit from the Simi Valley building department. This makes sure the installation meets local codes and is inspected for proper function. FKM Plumbing can help you navigate the permitting process.
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.
