Tankless Water Heater in Douglasville, GA

Which gas company serves my Douglasville house?

Check the gas bill. Austell Gas System, a city-owned utility run by the City of Austell, lists Douglasville among the places it serves, but not every Douglasville address is on its lines, and some may be on Atlanta Gas Light. This matters for a tankless install because a much larger burner can mean a bigger meter, and only the utility that owns the meter can change it. It also tells you who to call in an emergency: Austell Gas at 770-948-1841, option 1, or Atlanta Gas Light at 877.427.4321. For any gas smell, leave the house first and call 911 from outside.

Do I need a permit, and can I pull it myself?

The City of Douglasville Building Division takes plumbing permit applications through its BS&A online portal, and its homeowner permit list includes water heater replacements. A tankless conversion goes further than a like-for-like swap because it adds gas piping, a new vent and sometimes a condensate drain, so most homeowners leave the permit with the plumber who does the work. The Building Division is at City Hall on Spring Street.

Is WSA water a problem for a tankless heat exchanger?

The Douglasville-Douglas County Water and Sewer Authority supplies the city from the Dog River Reservoir, treated at the Bear Creek plant with free chlorine. WSA's service line inventory found no lead service lines in its system. The report does not state hardness, so a water test is the best guide to how often a tankless unit should be descaled. Homeowners own the lines from the WSA meter to the house, so any supply problem a plumber finds on that stretch is yours to fix.

Housing here is mostly 1990s and 2000s growth along I-20, with a median build year of 2001, so garages with an outside wall are common and vent runs tend to be short.

A quick local note

If you are replacing a tank that still works, it is worth getting the tankless plan in place first. Douglasville's I-20 subdivisions are full of builder-installed tanks of similar age, and they tend to fail without much warning.
