What a backflow test costs in Columbus
Two parts: a fixed City fee, and whatever your tester charges.
1. City of Columbus fee: $25.00 per device, per year
Set by City Code 1105.09 (items N and P), in effect since July 1 2011, and separate from the tester’s charge. City Consumer’s Page
2. The tester’s price
