Backflow Testing

Backflow Testing from Columbus Irrigation keeps your drinking water safe from contamination and your system on the right side of local code. We test, document, and certify your backflow prevention device so you have paperwork ready for inspectors and peace of mind at home or on the farm.
We use dependable gauges and proven procedures to check performance under real operating pressure, not just on a workbench. If something doesn't pass, we explain why in plain language and outline practical repair or replacement options before you spend a dime.
Whether your backflow is feeding a lawn sprinkler system, drip irrigation, or commercial plumbing, regular testing prevents dirty water from ever finding its way back into your clean supply. Call us when your renewal notice shows up, or before you start the season, and we'll keep the test quick, accurate, and low‑stress so you can get back to work.
