Alpharetta doesn't run its own water; Fulton County supplies it from the Chattahoochee, and the county report gives no hardness figure. Test your tap first, then match equipment to the result. Call the number on this page to be connected with a local plumber in Alpharetta.
Alpharetta homes run on Fulton County water and sewer. The county treats Chattahoochee River water at the Tom Lowe plant in Johns Creek, disinfects with chlorine and adds fluoride. Hardness isn't in the county report. About 57% of Alpharetta homes were built between 1980 and 1999, so a lot of water heaters, softeners and supply lines here are original or close to it. That means some treatment questions are really maintenance questions about equipment that has simply aged out.
What to do now
- Test the water. Use a hardness strip at a cold kitchen tap, or ask the plumber to bring a meter. The number decides whether a softener is worth it.
- Name the complaint. Crust and spots point to hardness. Pool-like smell points to chlorine. Rust color points to pipes or the heater.
- Check any existing unit. An older softener with an empty brine tank or a stuck valve may just need service, not replacement.
- Find the main. Whole-house equipment goes on the owner's side of the meter, near where the line enters the house.
- Ask about the permit. Alpharetta issues trade permits through its online portal; your plumber can say whether the job needs one.
Symptom and likely cause
| What you see | Likely cause |
|---|---|
| White crust on aerators and showerheads | Mineral scale; confirm with a hardness test |
| Chlorine smell from every tap | Normal disinfection; a carbon filter addresses it |
| Brown water only on the hot side | Sediment or corrosion inside the water heater |
| Softener running but water still spots | Exhausted resin, empty salt tank or wrong settings |
| Weak flow after a filter was added | Clogged cartridge or undersized housing |
| Salty taste at the kitchen tap | Softener regenerating too often or set for harder water than you have |
What affects cost
- Softener, carbon filter, sediment stage or a combination
- Equipment size for household flow and measured hardness
- Distance from the main to a drain and power
- Pulling out an old system and re-piping the bypass
- Recurring salt and cartridge costs
Fulton County runs a backflow prevention program from its Water Resources office in Alpharetta, and annual certified testing applies to testable devices. A standard softener install doesn't usually add one, but if your plumber recommends any assembly on the main, ask whether it is testable.
