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 These outdated business practices, inconsistent internal communication, and lack of basic financial controls introduce unnecessary risk for clients.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.

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!

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 started getting estimates from different companies, and Wyatt from Piper's came out to see the scope of the work. Whenever hiring contractors I try to understand beforehand the work involved with the hypothetical if I had to do the work myself, that way when walking through the project with the person giving an estimate it helps me figure out the rough bound of what I think the project should cost in labor and materials and to help me catch if there's additional "work" or costs that get put into the bid. With this in mind, when Wyatt walked through the issues he saw and roughly the work involved to fix the issues, it was nothing but an accurate assessment. I felt comfortable bouncing ideas of what made sense to try and tackle in the scope of the repair and what might be unnecessary as there was no real sense of an upsell, just what seemed like honest, professional opinions. Time is money for lots of these companies, and sometimes estimates get rushed which happened in some of the estimates I received; but not with Piper's. They took the time to understand what my priorities were, what constraints there were, and give fair realistic suggestions. After accepting what I believed to be a very fair bid, they were able to schedule the work and came exactly when they said they would. My plumber was Wyatt with a secondary helper - both did a fantastic job and were great at what they needed to do, so only praise there. They were respectful, used shoe covers and moving pads so as to not track dirt on my carpet, cleaned up all the debris from the work, and showed great care in their work. They also were considerate of my requests to minimize the cuts into the drywall and whereas many other bids told me it was necessary to cut drywall in three different rooms for the work they took on the extra inconvenience and were able to keep all the cuts contained to just the bathroom. Time will tell how well the work holds up, but as of now I have the utmost confidence the work will last.

Then I had another Plumber come out to look at it and told us this is NOT NECESSARY. He tightened the drain plug /overflow screws and that fixed the leaking problem. The water was just leaking in between that gap from overfilling the tub. But I'm giving you 4 stars because he DID advise me that I didn't need a water heater flush yet since it's only a year old. And he advised us we could easily do it ourselves, when I told him my husband and son work for SPU in Seattle. So your Plumber's honesty, professionalism and quick response to our call has earned out trust for future calls. Thank you.

Unethical. Exploitively overpriced. Cannot recommend. They leverage their "state certified"…read morereputation to overcharge to replace back-flow devices that can be repaired. Quoted replacement of two back-flow devices at $1,926 after they failed tests. Reader: you should call a commercial plumber instead. Compare to union labor @ $188/hr to clean, reassemble, and test both devices is less than $400. Even if a device needs to be replaced, the additional cost of the device is only $130. Shop around. For back-flow testing Pacific APC is convenient and economical. But for repairs and servicing, distrust. There are better back-flow device testing companies in your area.
