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.Paramount in numbers

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.
What makes an assembly fail
Debris on a check seat, a relief valve that weeps, a shut-off that will not close. Most failures are repairable in place with a rebuild kit rather than a replacement.
