It feels like all the Backflow companies want to just take your money and expect you to trust them…read moreto do the test for you at some point before it's due. 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!

Their technician showed up, presented me with a piece of my equipment that was now broken (wasn't…read morebefore they arrived) & said he could NOT do the test because it was broken. The company then billed me over $75 for the test that was never performed. No matter how much I argued or what proof I provided they demanded payment. Additionally, I subsequently had to pay another company to fix what they broke and to perform the test. If I could rate them negative 10 I would!

I called Affordable Backflow Testers and, probably by chance, they had a repair person in the area who was able to address the repair that same afternoon. Upon arrival, Taro was quick to confirm that the preventer had failed. He took apart the BFP, showed me how it had failed (fortunately a simple fix), repaired the device and retested. I received a full report 3 business days later. I was very happy with the firm and will plan to use them next spring.

I connected few companies, but they either quoted too high without even looking at, or not responding at all. From Marden, I received immediate response and whole team showed up next day on time.

He submitted my back flow testing papers and confirmed via email. He didn't charge for travel time (which other businesses did which I thought was odd). This guy seemed honest and very fair prices.

Highly recommend! Efficient, fast and reliable!! Glad we chose Axis for our backs flow testing!read more

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!

I can't say enough good things about this company. They have done a few projects for me now and I…read moream wowed by each. My first encounter was to have a leak in my sprinkler system fixed. It turned into a major project because they found that another pipe, farther up the line also had a crack, so they just kept on working, late into the evening, until everything was fixed thoroughly and buttoned up. The next project was to winterize my system so I don't have a similar problem next year. Well done, with a smile and great communication. Then we decided to put in a retaining wall which was a major project. But it was done right, and it has a solid base, deep in the ground, and nice, neat work with an attractive curve in line with the landscape. Clean up was awesome. The owner had lots of good ideas as we went, and I ended up with another attractive, usable area for my vegetable garden on my very sloped back yard. The owner has a great back story, and it's worth hearing! He's young, but experienced, and has his values in the right place for a successful business.

Well here comes my review which is not positive. I hired Nicholas and his company to take a look…read moreat my sprinkler system as some of the heads were not working. Nicholas's worker was doing all the work while Nicholas and I were talking. I thought Nicholas was a very nice young man who seemed to know his business. It turned out there were a lot more sprinkler heads needing some repair and I believe a pipe needing repair. During the time his worker was doing the work, Nicholas spoke to me about putting my sprinkler system underground. While I think it is a good way to go, I plan on selling my home and I don't wish to add additional items to an already updated everything. After 2 to 2.5 weeks of getting the sprinkler system worked on, I found while checking each and every head that many of the heads were not working. I was so dismayed that this was the case. I called Nicholas and told him what I found. It was obvious that some of the heads had been worked on because of course I remembered as his worker moved from one to another. He said it would be a service call. I said no it shouldn't be a service call because your company supposedly fixed all sprinkler heads needing repair. I sent a text to Nicholas on June 22 asking Nicholas to PLEASE HELP ME because some of the heads were not working and my plants, shrubs, flowers were not getting any water except from me as I was watering with a hose I sent another text to Nicholas on July 14 and another on July 31. The gist of both texts was for help and I told him I would be writing a not positive review. Never received any communication at all. I was so disappointed. I knew he was having his first child and I was really happy for him in building a business and he seemed so honest and trustworthy. What a disappointment.
