Got a backflow notice from your water district? Our state-certified testers handle your annual backflow test, file the report with the Portland Water Bureau within 10 business days, and repair or replace a failed assembly — at an upfront price.
A backflow preventer stops dirty water from being siphoned or pushed back into the clean drinking-water supply through a cross-connection — like an irrigation line, a fire line, or a commercial fixture. Because a failed assembly can contaminate the public water system, Oregon law (OAR 333-061-0070) and Portland City Code require every assembly to be tested at least once a year by a certified tester, with the results filed with your water provider.
We do the test, and if it passes we handle the paperwork — so you stay compliant without the hassle.
Portland Water Bureau and metro districts mail annual reminders — usually in spring, before irrigation season. Don't let it lapse: fines and water shut-off follow a missed deadline.
Have the letter or your assembly serial number handy and call us — we'll test it and file the report before your due date.
If your property has any cross-connection to the city supply, it almost certainly has an assembly that must be tested every year.

Fire sprinkler systems carry RPZ or detector assemblies that require annual certification.
High-hazard connections (dishwashers, carbonators, kitchens) need RPZ assemblies tested yearly.
Clinics and labs have high-hazard cross-connections requiring reduced-pressure protection.
Apartments, condos, and HOA common systems with irrigation, boilers, or fire lines.

Almost always yes — most residential assemblies protect an irrigation system, and Oregon requires them tested annually, usually before summer watering season.
Minor failures (worn seals or springs) are usually repairable for about $100–$500. Aging or repeat-failing assemblies are better replaced — residential replacements often run $300–$600 installed. We test, advise, and do both.
Briefly, yes — a test requires a short shut-off to read the differential pressure gauge. Most tests take well under an hour, and we restore service right after.
