VERIFIED THE BEST! The City of Mercer Island sent notice that we needed a backflow test. The notice…read moreincluded a list or 40 companies that were approved by the city. I loaded all 40 of them into my Claude AI program and asked the AI to tell me which one was the best. Which one had the highest ratings and had no bad feedback. It came back stating that 5 Star Backflow was the BEST of the 40 approved companies! I then called Josh, the owner of 5 Star Backflow, and he and his team worked around the clock to help me because I was up against a deadline. His communication with us was spectacular and thanks to him our water did not get cut off. We even had a complication with the backflow valve being broken, but he got it taken care of and he went way above and beyond to help us. I wish I could give him a 100 stars, because he is the real deal and he deserves a great review. If you need a backflow company, 5 Star Backflow is the absolute best! Thank you Josh!

I've been using 5 Star Backflow Services for my required city backflow inspections for years now…read moreand I've always been happy with the service, so it's probably time for a review. Once they had me in their system, they started contacting me in advance to schedule the test each year, which I really appreciate since the city notice doesn't usually give a lot of turnaround time. This year the city surprised me by sending the notice a month early, and I was on vacation when the notice came. This left me with just over a week before it was due. I contacted 5 Star Backflow Services and they were able to do the test just a couple days later. After the test they always send the report directly to the city within 24 hours. I have been very pleased with the service. Thank you!

Found Axis through Yelp and per the reviews they were spot on. The owner was extremely responsive…read moreand I never had to follow up. He showed up on time and as promised per his email.

While the field backflow testing service itself was adequate, the company's back-office operations…read moreare poorly managed and unacceptably disorganized. Their reminder system is not aligned with municipal requirements, and their billing and accounts receivable processes are fundamentally flawed. I was repeatedly told by staff that a prior invoice had not been paid, despite the fact that I retained written confirmation showing the payment was submitted through their Intuit QuickBooks link and acknowledged with a "thank you for your payment" email. Despite providing this documentation, the company unilaterally canceled a scheduled service appointment the day before it was to occur, citing non-payment. When confronted with proof, the explanation shifted to a claim that they "never received the funds from the credit card company," which is not a defensible position to place on a customer after confirming receipt. These outdated business practices, inconsistent internal communication, and lack of basic financial controls introduce unnecessary risk for clients. While I had initially intended to continue using this company, the operational failures and resulting service disruption make them unreliable and difficult to do business with. There are other providers who can deliver the same service with greater professionalism, transparency, and reliability, and I will be pursuing those alternatives going forward.

Oh, but you have no idea whether that's this week, next month, 4 months from now - who knows! Not Backflows Northwest. I called them to make sure the rates were accurate, and to get an idea of when they would do the test. The guy was super nice, and he said he'd do the test on Wednesday, and they said they'd leave a note on the door when it was completed. They did it a day early, and left the note on the door just like they said. This was exactly the ideal experience in my opinion, so I strongly recommend them!

After the work was completed, I was told the report would be sent to the city and I would get an invoice later for the work since there was an additional device that needed to be tested. I of course said ok and thought nothing more of it. Fast forward about a month later. I had already forgotten this issue since I was expecting an email. I get a letter from the city saying my test was incomplete and that my water will be cutoff soon. I called back and was told they had forgot to submit the report and they would do it ASAP. There were no mention of the second device cost so I thought maybe they were going to throw it in for free since there was a lateness. I of course then get an email with the invoice for the additional device and finally a few days later I think I was cc'ed on the report sent to the city. Now, if I had been out or didn't check my mail for a while I really could have my water turned off and I think that even affects my credit? That's not good.

Previously we had the testing done through the company that installed our gas boiler (Northwest Mechanical) but they decided to focus on the installation business and referred me to A+ Backflow. Initially there weren't any reviews for the business so I contacted Pops Backflow, but Pops was all booked up and referred me to A+ Backflow saying "Dave is very good and always shows up for his appointments. He has all his ducks in a row in regards to insurance, licensing, bonds, etc. He is honest and does everything by the book. I got him connected with NW and they have told me their customers are very happy with his service, I'm sure you will be too." Dave Kuca at A+ Backflow responded promptly to my call and was able to fit me in with short notice so I could meet the city's deadline. He did a great job and accepts credit cards with a Square reader.

Communication was poor, paperwork was never left under the doormat and results were not submitted to the water district until I contacted her multiple times. After numerous emails over the past week, I was forwarded the paperwork which had "sample" written on it. My address also appeared to have a 4 where there should've been a 9. I was told that it was correct and submitted to the district. Upon calling the district, there wasn't a record of it. All submissions are done online and there are things in place to make sure addresses are correct. I contacted Linda again and was forwarded a screen capture of the submittal of test results. The test date was incorrect since she had come the day before. Results were not submitted until they were a week past due. I am still not sure if she actually tested since she was questioning whether or not she tested the right house.
