I would first like to say thank you to Allen from C&L Plumbing for resolving my back flow situation…read moreso quickly and professionally. I would definitely recommend him to anyone that requires back flow service. Recently, I was notified to get my back flow tested for my building.

He was able to complete the job with ease and even gave me a discount which was fantastic.

While Nick was thoroughly booked with clients when I called him about getting a backflow device…read moretest, he referred me to a plumber whom he knew and trusted who could install and relocate the device to the proper location on my front lawn. After the device was installed, Nick stopped by briefly to certify the correctness of the installation and transmitted the report to the local water department prior to the deadline. Highly recommended.

After checking the City of Santa Rosa website, I found BG Backflow and reached out. Bryan got back to me right away -- he texted a few questions and, within two hours, sent over a clear and professional proposal. My test was already past due since I never received the first notice, but Bryan understood the situation and fit me into his schedule the very next day. He took care of everything quickly and professionally. The communication, customer service, and his expertise in backflow testing were outstanding. I highly recommend Bryan and BG Backflow. Great job, and I'll definitely be reaching out again next year!

This is for a backflow preventer on a gas boiler for a hydronic floor heating system. I'll then find Gavin in my contacts and send him a text.

Gavin advised me on what's needed, when the valve might need to be replaced (not yet) and why the checks are done. On one visit, a part unexpectedly broke during the check, and he was able to make a temporary fix and then come back the next day to fix it. Overall, a good service at a fair cost!
