Salem, Oregon, is the state capital with a population of about 175,000 and a growing mix of commercial, industrial, and residential properties. The city’s water system is managed by the City of Salem Public Works Department, which mandates annual backflow testing for all commercial irrigation systems, fire sprinkler systems, and any residential property with a potential cross-connection hazard. This creates a steady, recurring revenue stream for certified backflow testers. The market has moderate competition, with a handful of established plumbing companies and a few specialized backflow testing firms. However, many property managers and homeowners struggle to find reliable testers who respond quickly and submit reports electronically. There is room for a new business that emphasizes prompt service, clear communication, and digital compliance with the city’s reporting system.
In Oregon, anyone performing backflow prevention assembly testing must hold a valid certification issued by the Oregon Health Authority or an OHA-approved training provider. The most common certification is the Backflow Prevention Assembly Tester (BPAT) certification. You must complete an approved training course and pass a written and practical exam. The certification is valid for three years and requires continuing education to renew.
You will need a general business license from the City of Salem. Contact the Salem Business License Office to register your business. Additionally, if you perform any plumbing work beyond testing (such as repairs or replacement of backflow devices), Oregon requires a plumbing contractor license from the Oregon Construction Contractors Board (CCB). Even if you only test, carrying a CCB license is recommended for credibility and insurance purposes. You must also register your business with the Oregon Secretary of State (for LLC or corporation) and obtain an EIN from the IRS.
The City of Salem and most commercial property owners will require you to carry general liability insurance of at least $1 million and a pollution liability policy (since backflow testing involves water and potential contaminants). Oregon law does not mandate specific insurance for testers, but without it you will be unable to work on many commercial sites.
