Our small HOA recently had our backflow valves tested for 2025 by the company we had used for years. We had a problem with one of the valves last year and had it replaced to the tune of $850. Imagine our surprise when we got the results of this year's testing and the same valve failed again and, once again, needed to be replaced. After multiple attempts to speak with the company, we finally got an email saying that those valves are not very sturdy and the AZ heat causes them to fail routinely. Since the valve was less than a year old, that didn't make sense to us, so we decided to bring in another company for a second opinion. That was when we foundĀ F6 Backflow Services. We spoke to Dave, the owner, on the phone and explained our situation. He said it sounded "off" to him, too, soĀ we made arrangements for him to come out, take a look at it, and see what he could do. He came out the next day andĀ did some clean-up of the housing - and a couple of other things that I admittedly didn't understand. When he hooked up his gauges and retested, lo and behold, the valve passed. We can't thank Dave enough for his honesty and professionalism. Needless to say, F6 Backflow Services will be our provider going forward and we look forward to working with them in the future.

Was looking for a knowledgeable person who specializes in Backflow systems, Dave promptly arrived to quickly assess vthe problem, had repair parts on hand was done in no time. The cost was fair, and I will use his services if ever needed again.

They've been taking care of our commercial properties for a few years now. Been nothing but top notch, speedy, repairs done well, sends the report directly to the city. What else do you need!

What can I say, I couldnāt ask for a better experience. I had a backflow specialist that had been helping us out for several years, but he then retired. I was then quoted a ridiculously high amount for a leaky backflow with a recommendation to replace it, which I found to be nonsensical given that the backflow was only 10 years old. Anyway, I started looking for a new vendor, and I got Daveās number from another backflow specialist. Not only was he willing to travel down multiple hours to southern Arizona to help me out, he spent a great deal of time with me on the phone to explain what the possible problems were for a 6ā and 1ā backflow, and he even periodically communicated with me to give me an update. We settled on a price, which was far less than my previous backflow specialist quoted, and we were just waiting to have Dave receive a license from the city to repair the backflows. Fortunately (and unfortunately), my manager hired someone that was already contracted with the city to make the necessary repairs, so it was bittersweet in that the problem was solved, but I could not use Dave to complete the repairs. I hope to use Dave in the future for whatever projects we have, and he truly emphasizes both honest and amazing customer service, two qualities that seem to be diminishing in todayās society. I couldnāt recommend Dave more to anyone that needs to have their backflows checked and serviced, and I hope he gets to read this review because he really was helpful.

Dave is great. He showed up as promised and didnāt try to sell me on anything. He did his work with care and detail. True professional and I will always use him again and again. Wish more services were like him.
