Spokane Water publishes an annual list of backflow assembly testers who submitted a certificate of insurance and a Washington business license. This page is a searchable local copy of the 2026 PDF. It is not an official city site.
The 2023 list had Test / Install / Repair columns. The 2026 list does not — this page does not invent them. The PDF notes that tester prices vary; this page does not add prices.
Annual roster. Company, email, phone, and cell as printed. Some emails or phones are blank on the PDF and stay blank here.
No fire-line mark on the 2026 file. Section headings (Backflow Testers, Landscape, Fire Protection, Plumbing, Mechanical) are how Spokane grouped the page — not a fire-line eligibility flag.
