Who has to test

What this site is
CrossConnect is a referral service, not a contractor. We connect property owners and managers with independent contractors. Backflow assembly testing is normally restricted to testers holding a specific certification and using calibrated equipment, and the report usually has to reach your water purveyor — ask to see the certification and ask who files the report. We carry out no testing, we certify nobody, we do not set prices, and we never charge callers anything. Nothing here selects a device for any installation or states that any assembly is passing.Checking a credential in Oregon
Oregon licenses are issued by the Oregon Building Codes Division, Department of Consumer and Business Services, which publishes a public search you can use before work begins. Plumbing businesses in Oregon must also hold a Construction Contractors Board license, which is a separate search.

What that coverage looks like
The 19 counties in our Oregon footprint are served by many separate water suppliers, and each one decides which premises must test and how often. Washington County, with 84 covered ZIP codes, is the largest single block of them; Portland alone holds 60.
How a backflow testing job goes
A backflow test is a scheduled job that ends in a document. The assembly is isolated, the differential across it is measured, the result is written down, and the report goes to whoever requires it. A failed test means a repair or a rebuild and then a re-test; it does not mean the premises closes that day.
What the call asks about backflow testing
- What kind of premises it is and what is connected to the supply — irrigation, a boiler, a fire line, a commercial kitchen.
- Who is asking for the test: a water supplier, a health department, or a landlord.
- Whether there is an existing assembly with a serial number on it, and when it was last tested.

Before you call
A test is a scheduled job with a report at the end of it, not a repair. What the report has to show, and who it goes to, are on the pages above.
