    Fast, accurate and reasonable. Came at the agreed upon time and finished quickly. I'll use them every year from now on.

    I contacted another backflow company to conduct our yearly fire sprinkler backflow test and that's…read morewhen all the problems started. The technician said it failed inspection because of a leak. So, he told me that he needed to order a gasket repair kit and clean out the valves and gave me an estimate. But even after the replacement, it still kept leaking. So, then he said that it maybe a faulty check valve or "something more" and therefore, the safest alternative was to replace the entire assembly, which would've cost around $8,000+. So, I prayed and then started looking around for a 2nd opinion. That's when I found Dave. Dave came out to the site and did see that the backflow valve was leaking. He called me, gave me an estimate (which I thought was very reasonable) and took the backflow assembly apart. In less than 30 minutes, he examined both check valves and realized that there was nothing wrong with them. The problem was that one of the valves wasn't tightened properly and that was causing the leakage. He also commented that in his 20 years of testing and repairing backflow valves, he's never seen a valve this loose before. After tightening everything, it passed inspection immediately! Dave is the man! He is honest and very knowledgeable. He literally knows backflow assemblies inside-out and is my go-to guy for all backflow related issues.

    Our small HOA recently had our backflow valves tested for 2025 by the company we had used for…read moreyears. 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 found F6 Backflow Services. We spoke to Dave, the owner, on the phone and explained our situation. He said it sounded "off" to him, too, so 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 and 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 him 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 Dave in the future.
