Anaheim says you may only use a backflow tester that is on the city’s approved list, and the tester must hold a valid City of Anaheim business license. The PDF is two sections (companies, then named testers). This page copies the company section.
Official program page Official PDF (Last Updated: July, 2026)
Every company below is copied from Anaheim’s Certified Backflow Prevention Device Testing Companies pages (last updated July 2026). The named-tester pages later in the same PDF are not duplicated here.
