Roswell homes are on either the City of Roswell Water Utility or Fulton County water, and neither report lists a hardness figure, so testing comes before buying a softener. Both systems use chlorine, which is a filter question, not a softener one. Call the number on this page to be connected with a local plumber in Roswell.

How the call goes
You'll reach an independent plumber who works in Roswell. Expect a few questions: what you are noticing, how old the house is, whether there's an existing softener or filter, and where the main line comes in. If you already have a water bill handy, look at which utility sends it. That tells the plumber whose water report applies.
On a visit, a plumber will usually check hardness at a cold tap, look at fixtures and the water heater for scale, and suggest the simplest fix that addresses the complaint. Sometimes that's a softener. Often it is a carbon filter for taste, a cartridge change on an old system, or no equipment at all.
Cost drivers
- Type of equipment and how many stages it needs
- Pipe access at the main: garage, basement, crawl space or slab
- Whether a drain line and an outlet are within reach
- Removing and disposing of an old unit
- Salt, media and cartridge costs over the years
Roswell's two water systems
The City of Roswell Water Utility serves only part of the city, roughly 5,600 customers, from its Big Creek treatment plant with some purchased water. Everyone else gets Fulton County water from the Chattahoochee River, treated at the Tom Lowe plant in Johns Creek. Both disinfect with chlorine and add fluoride. Neither report lists hardness, so a test is the only real answer for your address. Fulton County handles all sewer in Roswell, even for homes on city water, so softener brine ends up in the county system either way.
Housing in Roswell has a median build year of 1989, with about 22% built before 1980. In the older stock near the historic mill-town core, supply pipes may be the source of any rust or sediment you see, which a filter can mask but not fix. For Fulton County customers, the homeowner's responsibility starts at the meter and runs to the house.
Before the plumber arrives
- Find your latest water bill and note which utility issued it
- Clear space around the main shutoff and the water heater
- Note which taps or fixtures show crust, stains or odor
- Have the model label of any old softener or filter handy
