Columbus DPU accepts test results only from testers who meet the Backflow Compliance Office requirements (Ohio DOC certification, Columbus building regs, BCO registration, calibrated kit) through the “Valid through” date. This page is a searchable local copy of the Testers Approved for All Devices PDF. It is not an official city site.
The PDF lists names in random order. This copy is sorted A–Z by tester name so you can find someone. Columbus also publishes a separate irrigation-only tester PDF; that file is not on this page.
Must-be-on. Only testers on the current BCO-approved list (through the valid-through date) will have results accepted.
No fire-line mark. This is the all-devices roster. Columbus does not highlight fire-line testers in red on this PDF. Do not treat “Fire” in a company name as eligibility.
Official fields only. Tester, Ohio DOC number, company, address, phone as printed — including odd spellings. One tester has a blank phone cell.
