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!

John answered immediately and offered to come out and repair it, but mentioned that based on my description of the problem I could probably just do it myself so he wouldn't have to charge me. He spent time on the phone with me walking through the fix, and 10 minutes later my problem was solved using a wrench and a screwdriver--without even needing any new parts! A business that wants to save you money and doesn't simply charge you as much as they can is so rare -- it takes real integrity. Needless to say I will be calling John when I need to have my annual test performed, and highly suggest you do the same! Thanks again John!

It took him about 20-25'. The technician was skilled, polite and efficient. I wrote them a check, but I was not given a written estimate, nor was I given a receipt. NO itemized information on the charges at all. It seemed like a lot of money!!! I called the secretary later that afternoon and she had the owner call me back. He listened to my concerns and we arrived at a compromise. So, just be informed of the charges beforehand and get multiple estimates if you can. Copperfield Plumbing is a reputable and flexible business and a good choice if your due diligence is complete.
