The City of Norcross requires a permit to replace a water heater, along with gas piping and fixture work that alters piping, so a proper replacement includes the city filing. Water and sewer have come from Gwinnett County since the county took over the city system in 2013. Call the number on this page to be connected with a local plumber in Norcross.

Norcross is a historic 1870 railroad town in southwest Gwinnett. Its median home was built in 1990, and about 18.3% predate 1980. Gwinnett County supplies soft Lake Lanier water, and Atlanta Gas Light owns the gas lines. The city's Community Development Department issues trade permits, including the one a water heater replacement needs.
What to do now
- Shut off the inlet. Turn the cold-water valve above the heater to closed.
- Turn off the heat source. Gas control to off, or the breaker off for electric.
- Manage the water. Towels, buckets and a wet vac keep a slow leak from spreading.
- Do not try to fix a leaking tank. Once the shell leaks, replacement is the only fix.
- If you smell gas, leave the house, then call 911 and Atlanta Gas Light at 877.427.4321 from outside.
Signs and likely causes
| Sign | Likely cause |
|---|---|
| Puddle under the tank | Tank failure or a leaking drain valve |
| Hot water runs out quickly | Sediment buildup or a failed dip tube |
| Discolored hot water | Corrosion inside the tank |
| Hissing or sizzling | Water dripping onto the burner from a leak |
| Relief valve discharge | High pressure, high temperature or a worn valve |
Cost factors
- Fuel type, capacity and efficiency

- Venting and shutoff valve updates
- Pan, drain and expansion tank where required
- Access in closets, attics and basements
- The trade permit and disposal of the old unit
The Norcross Community Development Department is at 65 Lawrenceville Street (678-421-2027), and trade permit documents are uploaded through the city's ePlan portal. Gwinnett County maintains the meter and the small pipe from the main to it; everything on the customer's side of the meter is the owner's. Gwinnett water is soft, averaging about 1.34 grains per gallon, so scale is less of a worry than sediment. Ask the plumber whether the permit is in the price. Because the city also permits gas piping separately, mention up front if you are thinking about moving the heater or switching from electric to gas, so both pieces can be filed together. Have the label details ready, and say where the heater sits, so the plumber can plan for a basement stair, an attic hatch or a tight closet.
