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

Why the Annual Test Is Required
Backflow prevention exists to keep the public drinking water clean. 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 Milwaukie-area water providers require the test annually and why it must be done by a certified tester. We're certified, we do 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. Milwaukie-area water providers require 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; testing confirms it still seals, which is why it's required annually.
My test failed — now what?
Usually worn seals, springs, or checks from normal wear. We repair or rebuild it, retest, and submit the passing result. A freeze-cracked assembly may need replacement instead.
Can freezing damage it?
Yes — above-ground irrigation assemblies can crack in a hard freeze if not drained and insulated. That's a common cause of spring test failures, so winterizing each fall pays off.
