Gwinnett County lists its water at about 1.34 grains per gallon on average, which is soft, so most Peachtree Corners homes don't need a softener. Chlorine taste, an aging softener or older plumbing are the usual reasons people call. Call the number on this page to be connected with a local plumber in Peachtree Corners.

What Peachtree Corners homes get from the tap
Gwinnett County's Department of Water Resources supplies Peachtree Corners with water from Lake Lanier, treated at the Shoal Creek and Lanier filter plants and disinfected with chlorine. The county's drinking-water page lists total hardness between about 1.05 and 1.87 grains per gallon, averaging 1.34. That's soft water. In practice, a whole-house softener in Peachtree Corners is rarely solving a hardness problem, and a salesperson who recommends one without testing deserves a second opinion.
The more common local story is age. Roughly 65% of homes were built between 1980 and 1999, with a median of 1989, so original water heaters, supply lines and older treatment systems added by past owners are common. Scale or sediment in a 30-year-old water heater, or a softener nobody services, can look like a water quality issue when it is really a maintenance one. Removing a softener that isn't needed also ends the cost of buying salt.
Matching the complaint to the fix
| Complaint | Usual fix | Softener needed? |
|---|---|---|
| Chlorine smell or taste | Carbon filter, whole-house or at the kitchen sink | No |
| Grit in faucet screens | Sediment filter or flushing the water heater | No |
| Rust tint on hot water only | Water heater inspection or replacement | No |
| Want very clean drinking water | Under-sink reverse osmosis | No |
| Heavy white scale everywhere | Test first; unusual on soft Gwinnett water | Only if a test shows it |
Signs worth a call
- An old softener leaking, cycling at odd hours or overflowing its brine tank
- Low flow after a filter cartridge was installed
- Slippery-feeling water and a salty taste, a sign a softener is set too high
- Discolored water from one fixture but not others
Timing and permits
A good moment to rethink treatment is when the water heater is due, since the same plumber can remove an unneeded softener and set up a filter near the main. The city, incorporated in 2012, issues its own building and trade permits through BS&A Online, not Gwinnett County. Gwinnett DWR maintains the meter and the short pipe from the main; everything on the house side, including any treatment equipment, belongs to the owner.
