Who has to test

Our backflow testing coverage in Mississippi runs to 156 ZIP codes in 107 cities. In a state that mixes large systems with small ones, a testing duty that is routine on one side of a county line can be unknown on the other, and the deadline a premises is held to is whichever its own water supplier sets.

We route backflow testing calls in 156 ZIP codes across 107 Mississippi cities, in 29 counties.

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 Mississippi

Mississippi licenses are issued by the Mississippi State Board of Contractors, which publishes a public search you can use before work begins. Mississippi licenses residential and commercial plumbing contractors; individual journeymen are not state-licensed.

What that coverage looks like

The 29 counties in our Mississippi footprint are served by many separate water suppliers, and each one decides which premises must test and how often. Hinds County, with 36 covered ZIP codes, is the largest single block of them; Jackson alone holds 27.

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 Mississippi city we route in

11 cities, ordered by the share of buildings with twenty or more units. Containment assemblies are required building by building, and that is where the buildings are. Each page carries that city’s own numbers and the ZIP codes we route there.

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.
