Recommended Customer Reviews
I would leave 0 stars if I could. They took over a local backflow business I had used for years and unfortunately BNW did not have the manpower or skill to manage these new clients. As a property manager I deal with at least 40 different service providers regularly. 99% are fantastic. Backflows NW is by a mile the worst service provider/contractor I have every worked with over 15 years. They can't return calls, promise they will show up and don't, can't fix things properly. All for what should be a very straight forward service. I gave them the benefit of the doubt for a year. I know it's hard to get employees, folks don't show up, front desk isn't always up to speed on issues, etc. Never left a google review before. Steer clear!
Stacy G.Easy to request the service. Price quoted was accurate! I will use them again and recommend them.
Backflows Northwest helped remove our backflow with ease. We were fortunate to have Seth working on our property who was very friendly and experienced. They also took care of submitting photos to the water district for the backflow removal. All for a reasonable price! Highly recommend :) Thank you!
Backflows northwest tested our water systems and they failed to tighten a backflow adjustment valve screw, leading to dripping water damage over time.
I have a written statement from the plumbing company, stating clearly that the water leak was caused by backflow tester not tightening the adjustment valve screw properly during the backflow test.
I communicated this to Backflows Northwest and their response was stunning: they tried to question the cause of the leak while acknowledging that there was a leak from the backflow valve in a last ditch effort of trying to weasel out of any liability. At the same time, and in good faith, I had booked them to perform another backflow test, assuming that they would stand by their earlier work and make things right, i.e., reimburse for the water damage repairs caused by their faulty work.
However, when asking for a response to the written plumber statement, this company explained that the only person who can reply had suddenly gone on vacation and they are unable to respond.
Needless to say, I'd stay away from this company at all costs.
John M.Backflows Northwest tested our yard irrigation in Lakewood, and the technician, Corey, was very thorough and professional. All readings were within limits, he updated the inspection placard, and then he left a testing summary for us on the door handle. Backflows Northwest and Lakewood Water District collaborate for this great service and allow me to use automated bi-monthly billing. This gives me the confidence knowing the certification process is complete and, more importantly, knowing our local water supply is safe and free of any harmful elements or toxins.
Srikanth K.Just as others said - very quick, efficient and affordable! Showed up quickly to accommodate the city's deadline, tested our backflow and even sent the report to the city! All I had to do was just pay them online.
Kevin came out and retested the backflow and found the problem of the city flushing out their pipes. Fixed it but said it would probably would not pass next year do to the age of the backflow. We decided that we would go ahead and replaced the backflow on Kevin's recommendation. No pressure to replace it, but trusted Kevin's good work and did not want to chance getting someone else next time. Very pleased with the work and good service.
Thank you for being customer focused. I love that you send me an invoice and all is taken care of in the background. And then I get a receipt hanging on my door, letting me know that it was all done. I wish there were more companies like you!
Aaron Z.Our townhome complex used Backflows Northwest for the past two years, and everything went without a hitch. The office staff helped us turn around the scheduling in a relatively short timeline, as our testing was coming due. They even reached out to the city on our behalf to let them know the testing was scheduled. The technicians were on time, friendly, and worked efficiently. All paperwork submitted to the city shortly after testing was done. Billing was simple, and they billed each unit individually in our group to make things even easier.
Overall great experience, and we plan to keep using them in the future.
Jimmy L.Showed up and finished the job quickly and painlessly. They sent the necessary paperwork to the city for me as well without my asking. Billed online, was easy to pay through credit card.
