A Lithonia water heater that fails usually has one bad part, like an element, a thermostat, a thermocouple or a valve, and a plumber can often replace it in one visit. A tank leaking through its own wall must be replaced. Call the number on this page to be connected with a local plumber in Lithonia.

Am I in the City of Lithonia or just the Lithonia mailing area?
It matters for permits. The City of Lithonia is a small historic granite-quarrying town around Main Street, but the "Lithonia" mailing area, ZIPs 30038 and 30058, is much larger and overlaps Stonecrest and unincorporated DeKalb. Inside city limits, the City of Lithonia Building and Permitting Division issues plumbing permits as their own trade permit type, at City Hall on Main Street or through its Citizen Portal. Addresses outside the city go to Stonecrest or DeKalb County instead. A heater replacement usually needs a permit; a simple part swap usually doesn't.
How old are the homes, and does that change the repair?
The city has older residential streets ringing its historic core, while the wider 30058 ZIP is mostly newer; in that ZIP, only about 16% of houses predate 1980. City-only housing figures aren't available. In older houses near Main Street, expect heaters in closets or utility rooms with older valves and connectors; in newer subdivisions, garage or attic installs with original heaters now reaching the end of their life. In either case, a plumber should look at the supply valves and connectors along with the failed part, and explain anything extra before adding it to the job.
Who handles water and sewer?
DeKalb County's Department of Watershed Management, not the city. Water comes from the Chattahoochee River and is treated at the Scott Candler plant. DeKalb owns the line through the meter and handles main breaks through its 24-hour line at 770-270-6243; the line from the meter to the house is yours. DeKalb's service line inventory lets you check your line's material.
Local note
Atlanta Gas Light is the expected pipe utility; there's no city gas department. If you smell gas near the heater, leave first, then call 911 and Atlanta Gas Light at 877.427.4321 from outside. When you call, mention whether you're inside city limits and where the heater sits. If water is on the floor, close the cold supply valve above the tank and turn off power or gas first. Have the label's age and fuel type ready so the plumber can bring likely parts.
