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.Harrison Township in numbers

Backflow Testing coverage in Harrison Township, MI
Harrison Township is in Macomb County, Michigan. Its ZIP code is 48045. We route backflow testing calls from 48045.
Who requires the test
The water purveyor requires it, on a schedule it sets, usually annually. The plumber performs it; the certificate goes to the purveyor, and keeping a copy is the customer’s problem.
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.
