Most Peachtree Corners homes were built in the 1980s and 1990s, and copper water lines under slabs of that age are where hidden leaks start. Gwinnett County maintains the meter and the pipe to it; everything on the house side is the owner's. Call the number on this page to be connected with a local plumber in Peachtree Corners.

Local conditions
Peachtree Corners, Gwinnett County's largest city, sits on the Chattahoochee in the county's western corner and mixes 1970s through 1990s subdivisions with the Technology Park office campuses. Census survey figures via Point2Homes put the median year built at 1989, with about 65% of homes built between 1980 and 1999. Those houses are now roughly twenty-five to forty-five years old, the age at which buried supply pipe starts to show wear.
Water and sewer come from Gwinnett County Department of Water Resources, which treats Lake Lanier water and disinfects with chlorine. Gwinnett water is soft, around 1.3 grains per gallon on average, so mineral scale is not the usual culprit. Under a slab, pipe is more likely to fail where it rubs on concrete or stone or at a joint.
Gwinnett maintains the meter and the small pipe from the main to it. The private service line beyond the meter, and everything in the house, belongs to the owner. The City of Peachtree Corners, not the county, issues trade permits, through its BS&A Online portal.
Which repair fits
| Option | Typical reason | What's involved |
|---|---|---|
| Direct repair | One leak, clean pipe nearby | Open a section of floor, splice new pipe, patch concrete and flooring |
| Bypass | Aging copper or a known weak run | Cap the buried line and route new pipe through walls or attic |
| Full repipe | Several leaks or poor pipe throughout | Replace supply lines across the house |
Signs to check
- Meter leak indicator moving with no water in use
- Warm or damp spots on a ground-floor slab
- A water heater that runs constantly
- Bills higher than the same month last year
- Faint running water sounds at night
Timing
A leak that starts small can grow. Schedule a test when you first notice two or more signs together. If it's summer, turn off irrigation before reading the meter so lawn watering doesn't confuse the result. In winter, a hot water leak under tile is easier to feel because the rest of the floor is cool.
If you are planning a kitchen or bath remodel anyway, mention it to the plumber. Opening walls for a remodel can make a reroute simpler, and it may be the right moment to replace older supply lines in the same area rather than come back later.
