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 New York
New York issues no state plumbing license. New York City licenses Master and Journeyman Plumbers through the Department of Buildings; elsewhere in the state it is your own city, town or county. Start here. Ask the contractor which municipality licenses them and confirm it with that office before work begins.

What that coverage looks like
The 35 counties in our New York footprint are served by many separate water suppliers, and each one decides which premises must test and how often. New York County, with 149 covered ZIP codes, is the largest single block of them; New York alone holds 149.
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.
Every New York city we route in
