Welcome to Bay Area Backflow, Inc.

Bay Area Backflow, Inc., is a dedicated team of professionals licensed to provide backflow prevention testing, repairs, installations, and Cross Connection Control Surveys throughout the Bay Area and Tri-Valley. We have been performing these services for 28 years. By providing exceptional service at reasonable cost, our list of satisfied and return customers continues to grow.

San Jose, San Mateo, Palo Alto, Fremont, South San Francisco, Monterey, Gilroy, and Livermore are just a few of our service areas. We are on approximately 25 different approved tester lists throughout the Bay Area. We provide service on all types of backflow devices from ½" – 10." No job is too big or too small. When it comes to larger devices (3" - 10" backflows), our experience and attention to detail will provide you with a backflow installation you can depend on.

By having the proper equipment and stocking the essential parts to repair the backflow device and its components, we can provide you with a complete job at the initial service call, saving you both time and money. We have a designated backflow installation team. Our truck is equipped with a crane that will lift up to 6,000 lbs. This allows us to work safely, professionally, and quickly to install or replace the larger backflow assemblies, with less down time to you and your tenants or residents. (You might consider bolding "saving you both time and money" in addition or in place of "designated backflow installation team."

Communication and follow through are the keys to success. Our uniformed technicians are scheduled in advance with specific time frames, for arrival to your property. This allows you to give notice of the water shut down, if necessary. Once the work is complete and the valve is in compliance, we send the original backflow test report to the water company. A copy will also be provided to you with your invoice.
