Stonecrest has no water department of its own, so DeKalb County Watershed Management sets the rules: single-family homes need a backflow assembly on any irrigation system, and every assembly must be tested once a year by a GBPAT-certified tester. Call the number on this page to be connected with a local plumber in Stonecrest.

Signs you need a backflow visit
- A DeKalb notice that your annual irrigation test hasn't been received
- Sprinklers installed at a newer home with no assembly anywhere on the line
- A drip or puddle around the device on the customer side of the meter
- Freeze damage after a cold snap left the assembly full of water
- A home sale where the buyer or lender asks for a current test report
Stonecrest on DeKalb water
Stonecrest became a city in 2017 and is the largest city entirely inside DeKalb County. It sits in the county's far southeast corner, around The Mall at Stonecrest and I-20, with the Arabia Mountain heritage area to the south. Water comes from DeKalb County Department of Watershed Management, which treats it at the Scott Candler plant.
DeKalb's Backflow Prevention Section covers every DWM customer. For houses the trigger is irrigation: a single-family home with a sprinkler system needs an assembly. Commercial and multi-family properties need one matched to their hazard level. The assembly goes on the customer side of the meter, is installed by a plumbing contractor holding a Georgia license, and has to be tested every year by a tester certified through GBPAT. GAWP keeps the list of certified testers, and the section can be reached at 404-687-4075.
DeKalb owns the line from the main through the meter. Past the meter, the service line and the assembly belong to the homeowner, so the yearly test and any repair are your cost.
Plumbing in Stonecrest is permitted by the city's Building Department through its Citizenserve portal, with plumbing listed as subcontracted work on a building permit.
What affects the cost
- Test only, or test plus parts and retest
- Double check versus reduced pressure assembly
- Whether the body survived the last freeze
- Assembly location and how much digging or clearing it takes
- New installation, which brings permit and inspection steps
