Backflow Testing: What OWASA Requires
If your property has an irrigation system or another cross-connection to the municipal water supply, OWASA requires annual backflow prevention device testing. Here's what that involves.
Why It's Required
A backflow preventer stops contaminated water from being siphoned back into the clean municipal supply during a pressure drop, protecting the whole system, not just your property.
What Testing Involves
A certified technician tests the device's check valves and relief valve under controlled conditions and files the results with OWASA on your behalf.
What Happens If You Skip It
Non-compliance can result in notices from OWASA and, in some cases, water service restrictions until the device is tested and results filed.
