Company Overview

Since its inception in 2003, Certified Backflow Testing has been the trusted provider for numerous homeowners, businesses, and municipalities every year. We perform backflow testing services anywhere in the Puget Sound, so that this yearly obligation becomes so simple, you might forget about your backflow assembly altogether! We provide simple scheduling, efficient communication, and honest pricing. we send you a copy of your report for your records, and we submit your backflow report to the relevant water authority at no additional cost. Best of all, our automated system reaches out to you each year to remind you of the service—just confirm your property ownership, and we manage everything else! The original owner of Certified Backflow Testing (CBT), Loren Hansen, operated his small backflow testing company from his residence. After two decades of consistent growth, Loren sold CBT to a major commercial plumbing firm, Seattle Tacoma Olympia Plumbing STOP Inc, in 2023. Currently, CBT is among the largest backflow testing firms in Washington State, servicing thousands of assemblies yearly and performing hundreds of repairs and installations each year.
