Kennesaw's water comes from the Cobb County Water System, whose backflow program requires protection wherever a cross-connection could contaminate the public supply and annual testing by a tester registered with Cobb County. Reports go through the SwiftComply portal. Call the number on this page to be connected with a local plumber in Kennesaw.

Kennesaw on Cobb County water
Kennesaw's Building Services page lists the Cobb County Water System as its related water agency, and Cobb says it serves the city. So Cobb's Backflow Prevention Program applies: any property with a potential cross-connection needs a backflow prevention device, and every non-residential customer needs a testable assembly on each water service connection. With Kennesaw State University and the Cobb Parkway corridor nearby, there are plenty of businesses and rental properties covered by that rule, and many 1990s and 2000s homes with irrigation fall under it too.
What to do now
- Locate the assembly. Look near the meter or the irrigation tap, and write down its make, size and serial number.
- Find the last report. Cobb requires a passing test every year.
- Choose a registered tester. Cobb publishes an approved list of testing companies; testers must be registered with the county.
- Confirm the filing. Reports go through the SwiftComply portal.
- Repair failures. A failed assembly needs fixing and a passing retest.
- Permit new installs. Kennesaw Building Services takes all permit applications online through its iWorQ portal and enforces the 2024 International Plumbing Code with Georgia amendments.
- Protect it for winter. Drain and insulate an above-ground assembly before the first hard freeze.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Water weeping from the body | Tired O-ring or check seat |
| Relief port flowing on an RP unit | Debris holding a check open |
| Cracked brass | Water trapped inside during a freeze |
| Zones losing pressure | Shutoff not fully reopened, or a sticking check |
| Leak at a test cock | Worn ball valve in the cock |
Cost factors
- A routine pass or a repair and retest
- Double check versus reduced pressure assembly
- Number of service connections, which matters most for commercial owners
- Replacing a frozen or obsolete unit
- Permit and inspection steps for new devices
Owners of rentals near the university should keep a copy of every passing report, since a tenant change is no reason for the annual schedule to slip. Cobb is responsible for the line from the main to the meter. The assembly and the pipe on to the building are the owner's, so the test and any repair fall to you.
