Smyrna's Water and Sewer Division runs the city's water system, but we didn't find a published backflow testing program with a set interval or tester list. If the city asks for a test or you're adding irrigation, ask the division what it requires. Call the number on this page to be connected with a local plumber in Smyrna.

What happens when you call
The number on this page connects you with an independent plumber who works in Smyrna. Describe what you need: a test the city or a buyer asked for, a device that's leaking, or protection for a new sprinkler system or a business connection. If you've received anything in writing from Smyrna's Water and Sewer Division, have it in front of you. The plumber can look at the device, explain what it is and what it protects, and tell you whether a rebuild or a replacement makes more sense.
What affects the cost
- Testing an existing device versus installing a new one
- Assembly type, since reduced pressure units have more internal parts
- Whether repairs need a full rebuild kit or just a seal
- Access around the meter on a small, dense lot
- Permit and inspection steps for new work
Backflow and Smyrna's water system
Smyrna is a dense inner-ring suburb near the Cumberland area, and it handles its own water distribution through the Water and Sewer Division at the Public Works Complex on Atlanta Road. The city buys treated water from the Cobb County-Marietta Water Authority and delivers it through its own pipes. That makes Smyrna, not Cobb County, the utility whose rules apply to your service.
Here's the honest picture: our research did not turn up a published backflow program for Smyrna water customers, so we can't tell you a required test interval or which testers the city accepts. That doesn't mean there's no requirement. Irrigation systems and commercial connections are the usual triggers for backflow protection across the metro, and a property in either group should ask the division directly before assuming nothing is needed.
The city maintains the system up to and including the meter, while the homeowner owns the line from the meter to the house. Any backflow device on that line is the owner's to maintain. New plumbing work is inspected by the Community Development Building Division under the 2024 International Plumbing Code with Georgia amendments, and permits go through the city's OpenGov portal.
Short checklist before the plumber arrives
- Call Smyrna Water and Sewer and ask whether your account needs a device or a test
- Find the device, if there is one, and note its tag
- Locate your main shutoff
- Close the irrigation valve if water is spraying
