Austell runs its own water system, and its backflow program directs medium- and high-risk businesses on installing the right devices. The page doesn't state testing intervals or tester rules, and many Austell-mailing homes outside the city's service area are likely on Cobb County water instead. Call the number on this page to be connected with a local plumber in Austell.

Austell's water system and backflow
Austell is a small south Cobb city that began as a healing-springs settlement and grew as a railroad depot town. The City of Austell Water System serves about 3,300 customers, roughly 63% of them inside city limits, in an area bounded by Clay Road, the Douglas County line, Noses Creek and Buttermilk Creek. Plenty of Austell mailing addresses, including much of unincorporated south Cobb around Six Flags, sit outside that area and are likely on the Cobb County Water System. Check your bill, because the two utilities have different rules.
The city's backflow prevention program is aimed at businesses: it directs medium- and high-risk businesses in the city on installing appropriate devices. The page we reviewed doesn't state an annual testing requirement or tester rules, and it doesn't describe a residential requirement. If you're a city customer with irrigation or a business, ask the Water Division.
What to do now
- Check your bill. City of Austell water or Cobb County water decides which program applies.
- City business owners: ask about risk level. The city decides which devices medium- and high-risk businesses need.
- Ask about testing. Find out from the Water Division how often devices must be tested and by whom.
- Cobb customers: follow Cobb's rules. Cobb requires annual testing by a tester registered with the county, filed through SwiftComply.
- Get repairs done. A rebuild usually fixes worn checks; a cracked body means replacement.
- Permit new work. Austell requires plumbing permits to install, alter or replace plumbing piping and fixtures, through its online portal.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Steady drip at the device | Worn check seat or seal |
| Relief port discharging at a shop or restaurant | Fouled check or pressure fluctuation |
| Cracked casting | Freeze damage |
| Pressure drop downstream | Partly closed shutoff or debris |
Cost factors
- Device type set by the business's risk level
- Test only versus rebuild and retest
- Replacement after freeze damage
- Access in a tight commercial space or meter box
- Permit steps for new installs
When you call, say which utility bills your water and what the device protects, so the plumber knows whose rules to follow.
