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!

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!
