Chamblee is on DeKalb County water, and DeKalb requires a backflow assembly on single-family irrigation systems, tested every year by a GBPAT-certified tester. Commercial and multi-family properties need assemblies matched to their hazard. Call the number on this page to be connected with a local plumber in Chamblee.

What happens when you call
You'll be connected with an independent plumber who serves Chamblee. Say whether the property is a house with sprinklers, a multi-family building or a business, and what you need: a test, a repair or a new assembly. If you've had a letter from DeKalb, have it handy. For a test that DeKalb will accept, ask whether the plumber is GBPAT-certified.
What affects the cost
- Routine test versus rebuild and retest
- Reduced pressure assemblies, which are common at higher-hazard businesses
- Number of connections on a commercial or multi-family site
- Freeze damage requiring a new unit
- A city permit for installing or replacing plumbing
Chamblee on DeKalb water
Chamblee has no water department of its own; DeKalb County Department of Watershed Management runs the system and has been replacing the waterline along Peachtree Boulevard. DeKalb's Backflow Prevention Section covers every DWM customer. Commercial and multi-family properties need an assembly matched to their hazard level, and single-family homes need one on any irrigation system. Each assembly sits on the customer side of the meter, is installed by a plumbing contractor holding a Georgia license, and must be tested every year by a GBPAT-certified tester. GAWP keeps the list, and the section answers at 404-687-4075.
That commercial rule touches a lot of Chamblee. The Buford Highway International Corridor is lined with restaurants, markets and shops, and food service is the kind of use that usually calls for a higher-hazard assembly. On the residential side, about 47% of homes were built before 1980, so sprinklers at older houses were often added later.
DeKalb owns the service line from the main through the meter. The owner is responsible from the meter to the building, including the assembly. Chamblee requires permits to install, alter or replace plumbing systems, and applications and fees go through its iWorQ portal.
Before the plumber arrives
- Find the assembly and note the make, size and serial number
- Pull last year's test report if you have it
- Clear access to the meter pit or device
- Close the irrigation or fixture valve if it's leaking
- For a business, list every water connection so none is missed
