We are saddened to announce that West Coast Backflow has closed its doors on May 31st, 2026.
West Coast Backflow will continue to provide support for our current customers and maintain our FAQ, Devices, and Resources pages for a bit longer.
We unfortunately will no longer be taking on any new customers at this time, and will no longer be performing any testing or installations.

It has been an incredible journey over the past 34 years, serving the Tri-Valley area and neighboring communities in the Bay Area.
We are deeply grateful for all the support, loyalty, and friendships we have built with all of our amazing customers and vendors over all these years.
Thank you for being a part of our story — it’s been an honor to serve you.
