About Us

American Backflow Services

  • Our Story: We were established in 1995 by two brothers: Tony and Brian Johnston. We worked out of Tony’s garage for the first 2 years then moved to a rented space for a year. Finally we moved to our current location on Interstate Avenue in Portland, Oregon back in 1998. After a while, we were joined by younger brother Mike Johnston and then soon after, our final brother (in-law) Kyle Harms.

    Our vision from the beginning was to provide uncompromising service and value to the customer. We have always understood the”golden rule” and have sought to implement that ideal not only to our customers but to our employees also.

    We opened a branch in Seattle, Washington in 2014 and it is slowly getting established. Our hope is to grow into the Seattle area like we have in Portland over these many years. We currently have 15 full time employees to meet all of your Backflow needs (including 5 Journeymen Plumbers).
