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.Gresham in numbers

Backflow Testing coverage in Gresham, OR
Gresham is in Multnomah County, Oregon. It covers 2 ZIP codes: 97030, 97080. We route backflow testing calls from every one of them.
Containment, not isolation
A containment assembly at the service entry protects the public main from the building. An isolation assembly inside protects the building from one fixture. They are tested separately and the certificates are not interchangeable.
The paperwork is the deliverable
A test that is not filed is a test that did not happen as far as the purveyor is concerned. Ask who files it and get the confirmation.
