We are saddened to announce that West Coast Backflow will be closing its doors on May 31st, 2026.
West Coast Backflow will continue to test backflows for current customers but unfortunately, we are not not taking any new customers at this time.

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.
