Norcross requires a permit to replace a water heater and for gas piping, so a tankless conversion is permitted work from the start. Gwinnett County took over the city's water system and supplies soft water. Call the number on this page to be connected with a local plumber in Norcross.
Norcross basics
Norcross is an 1870 railroad town in southwest Gwinnett, with a town square downtown and a median home built in 1990. About 18% of homes predate 1980. Gwinnett County took over the city's water and sewer system in 2013, replacing city meters with county meters, so water now comes from Gwinnett County Department of Water Resources. Atlanta Gas Light owns the gas pipes.
What to do now
- Gas odor? Get out. Then call 911 and Atlanta Gas Light at 877.427.4321 from outside.
- Record the code. On a tankless unit, write down the error number before resetting.
- Check power and gas. Make sure the unit is plugged in and its gas valve is open.
- Look at the vent. Make sure the outside termination is clear.
- Plan for the permit. Norcross requires one for water heater replacement and gas piping. Documents go through the city's ePlan portal.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Cold water mid-shower when another tap opens | Gas supply or unit size |
| Unit will not ignite | Gas valve, igniter, vent or power |
| Slow loss of hot water flow | Clogged inlet screen or scale |
| Water dripping from the unit | Condensate drain or a fitting |
| Tank leaking | Corrosion; replacement time |
Cost factors
- Gas pipe sizing from the Atlanta Gas Light meter to the unit
- Vent route through a sidewall or the roof
- Condensate drain and neutralizer for condensing units
- Unit capacity and any recirculation
- City trade permit through Community Development at 65 Lawrenceville Street
Older homes near the downtown square are the main exception to easy installs: a heater in an interior closet there may need a new vent path and a gas line sized for a tankless burner. Subdivision homes from the 1980s and 1990s usually have a garage wall to work with. A faucet or toilet swap with no piping change does not appear to need a permit in Norcross, but a heater change does.
Gwinnett water averages about 1.34 grains per gallon of hardness, which is soft, so extra treatment is rarely needed for the heater's sake. A yearly flush is still a good habit.
