Best Repairing Backflow Devices in Portland OR

I had a great experience with ABS in Portland and look forward to working with them going forward for our annual backflow preventer testing. Scheduling via their website was easy and convenient. At what I presume was peak season, available service dates were only about two weeks out. Follow-up communication from ABS was timely. Service was set for a very reasonable 2-hour window, with the technician arriving in the earlier part of that. The technician was friendly, professional, knowledgable, patient, and amiably informative as I curiously watched him work (not having, myself, any prior awareness of this testing)—he more than surpassed my expectations. The required paperwork was promptly prepared and submitted to the Water Bureau by ABS, and they emailed me a copy for my records. I couldn’t be happier with the experience and give ABS my full endorsement!
