Suwanee homes are on Gwinnett County water, which covers the meter and the pipe from the main to it; past the meter, leaks are the owner's. Most Suwanee homes are newer, so a plumber usually checks fittings, valves and irrigation along with the yard line. Call the number on this page to be connected with a local plumber in Suwanee.

Suwanee's housing is young. The median home was built in 2003 and only about 3% predate 1980. That changes where leaks show up: corroded pipe is rare, but newer homes have many joints, crimp rings, plastic valves, braided hoses and irrigation zones, and any one of those can seep for a long time before it shows.
What to do now
- Turn off every faucet, the ice maker, the washer and the irrigation controller.
- Read the Gwinnett meter and its low-flow indicator, wait an hour and read again.
- If the meter moved, close the main shutoff and check once more to see whether the leak is in the yard line or indoors.
- Look under each sink, behind the refrigerator, at the washer box and around the water heater.
- Run one irrigation zone at a time and watch for soggy spots or a zone that never stops dripping.
- For a break near the street, call Gwinnett County's 24-hour line at 678.376.7000.
Signs and likely causes
| Sign | Likely cause |
|---|---|
| Swollen cabinet floor under a sink | Leaking supply hose or compression fitting |
| Water stain on the ceiling under a shower | Shower valve or drain connection |
| Puddle behind the fridge | Ice maker line or its saddle valve |
| Wet strip across the lawn | Cracked irrigation lateral |
| Meter moves with the house valve closed | Service line between meter and house |
What affects the cost
- Whether the leak is reachable or sealed under a slab or finished ceiling
- How much testing it takes to isolate the right branch
- The repair, from a single connector to a section of line
- Permits: Suwanee requires permits for changes to plumbing systems, and lists water heater replacement as an example; applications and inspections go through the city's online portal
Gwinnett County maintains the meter and the small pipe from the main. The private service line, the full sewer lateral and any backflow preventer are the owner's responsibility.
When you call, you'll be connected with an independent plumber who works in Suwanee. Have your two meter readings ready and mention whether the house has irrigation, since that is often the first thing checked in neighborhoods built after 2000. If the leak is under a slab, ask about both a direct repair and rerouting the line.
