In Roswell, a water heater replacement is permitted through the city's Community Development Department, where plumbing is a trade added to the permit with its own affidavit and license paperwork. The city's median home dates from 1989, so many tanks are at replacement age. Call the number on this page to be connected with a local plumber in Roswell.

What happens when you call
You will be connected with an independent plumber who works in Roswell. They will ask what the heater is doing, the fuel, the gallon size and where it is installed. If it is leaking, they will help you shut off the cold supply and the gas or breaker. Then they visit to check the vent, gas line, relief valve drain and the space, and quote the replacement with the permit included.
What affects the cost
- Gas, electric, tankless or heat pump, and capacity
- Vent connector and gas connector condition
- Updating original valves and flex lines in 1980s and 1990s homes
- Basement, garage, closet or attic location
- Pan, drain, relief line and expansion tank requirements
- The city permit and removal of the old heater
Roswell conditions
Roswell grew from an 1850s textile mill town into an affluent north Fulton suburb. The median home was built in 1989, and about 21.9% predate 1980, mostly in and around the historic district.
Water depends on the address. The City of Roswell Water Utility serves part of the city, about 5,600 customers, from its Big Creek treatment plant; everyone else gets water from Fulton County. Both systems disinfect with chlorine rather than chloramine and add fluoride, and neither reports hardness. All sewer in Roswell is handled by Fulton County, even for homes on city water. Your water bill shows which system you are on.
The City of Roswell Community Development Department's building permit application has checkboxes for plumbing, electrical and mechanical trades, each requiring a subcontractor affidavit, business license, state license and photo ID; the number on the application is 770-641-3780. Water heaters are not mentioned by name, so the plumber should confirm what the city expects.
Atlanta Gas Light maintains the area's gas lines. If you smell gas, leave the house, then call 911 and Atlanta Gas Light at 877.427.4321 from away from the leak.
