Backflow Testing & Certification in Portland, OR
Got a notice from your water bureau about an overdue backflow test? We handle the testing, certification, and paperwork filing — so you're compliant without the runaround.
Backflow Testing Built Around Portland
A lot of inner Portland is older multi-family buildings — duplexes, triplexes, converted houses — with fire sprinkler systems and irrigation lines that haven't seen a backflow test in years. If you just got a compliance notice in the mail, you're not alone, and it's usually a quick fix once we're out there.
We test, certify, and submit the paperwork to your water provider so the compliance side is handled, not just the wrench-turning. If the assembly fails, we'll quote the repair before doing any work.
Who Needs Backflow Testing in Portland?
If your building has a fire sprinkler system, an irrigation line, or you run a restaurant or commercial kitchen, your water provider almost certainly requires an annual backflow test. Landlords managing older Portland multi-family buildings are the ones we see fall behind most often — usually because nobody tracked it as their job until a notice showed up.
What's Involved
The Test
A certified tester checks the assembly under pressure to confirm it's actually preventing backflow — not just installed and forgotten. Takes 30–60 minutes per assembly.
The Certification
We file the results directly with your water provider so you're not the one tracking down forms or chasing submission deadlines.
The Repair (If Needed)
If it fails, we quote the fix on the spot before touching anything. Once repaired, we retest and re-file the certification — handled start to finish.
What to Expect When You Call Us
Here's exactly how a backflow testing visit works — from scheduling to certification in hand.
We schedule a time that works for your property, show up with the testing equipment, and perform the certified pressure test on your backflow prevention assembly.
If it passes, we generate the certification report and file it directly with your water provider — Portland Water Bureau, Tualatin Valley Water, or whoever your purveyor is.
If the assembly fails, we quote the repair on the spot before doing any work. Once repaired, we retest and re-file the certification — handled start to finish.
What Does Backflow Testing Cost in Portland?
Most standard backflow tests in Portland run $75–$150 per assembly. If repair is needed, pricing depends on the assembly type and what failed — we quote it before touching anything. Multi-assembly properties (those with both irrigation and fire lines) get a bundled rate when tested together.
Common Questions About Backflow Testing in Portland
Who requires backflow testing in Portland?
Portland Water Bureau requires annual backflow prevention assembly testing for all properties with irrigation systems, fire sprinkler lines, commercial kitchen connections, or any cross-connection between the municipal water supply and a secondary source. Non-compliance can result in water service termination.
How often does backflow testing need to happen in Portland?
Once per year, minimum. Portland Water Bureau requires annual certification, and the deadline is based on your assembly's registration date. If you've missed a year or two, getting current is straightforward — we test, certify, and file, and the slate is clean.
What happens if my backflow preventer fails the test?
We'll show you exactly what failed and quote the repair before doing any work. Common failures include worn seals, failed check valves, or debris in the assembly — most are fixable in the same visit. After repair, we retest on the spot and file the updated certification.
Can you file the certification paperwork directly with Portland Water Bureau?
Yes. We're a certified tester with Portland Water Bureau, which means we submit the test report directly to them on your behalf. You don't have to track down forms or figure out the submission process yourself.
