When You Need Backflow Service
- You received an annual backflow test notice from your water provider
- You installed a new irrigation or sprinkler system

- You bought a commercial property and inherited the testing requirement
Why the Annual Test Is Required
Backflow prevention exists to keep the public drinking water clean. Oregon City's water is supplied through the South Fork Water Board, and any property with an irrigation system, fire line, or certain commercial connections has a cross-connection where non-potable water could be pushed or siphoned back into the supply if pressure drops. The backflow assembly stops that — but only if its internal checks and seals still seal, which wear over time. That's why the test is required annually and why it must be done by a certified tester. We're certified, we run the test, and we file the result so you stay compliant without the hassle.

Frequently Asked Questions
Do I have to test every year?
Yes. Oregon City's water provider requires an annual test of backflow assemblies to protect the drinking water supply. Irrigation, fire, and certain commercial connections all qualify, and a certified tester must submit the result — which we handle.
What is backflow?
When water reverses and flows back into the clean supply — for example, irrigation water siphoned back if pressure drops. The assembly prevents it; the annual test confirms it still seals.
My test failed — now what?
A failed test almost always comes down to internal parts that have worn past their seal point — the checks, springs, or rubber. We rebuild the assembly on site where we can, run the test again, and file the passing paperwork; if a freeze has cracked the body, we swap the whole unit and re-certify it.
Can freezing damage it?
Definitely. Since the irrigation assembly sits out in the open, a cold snap can split its body or ruin the internals if it wasn't blown out and wrapped before winter — which is why a lot of assemblies pass in fall and fail the following spring. Winterizing it each autumn heads that off.
