Alpharetta doesn't provide water or sewer; Fulton County serves the city and unincorporated north Fulton, and private wells are few, with no source counting them. If your water weakens or stops, a plumber can check the regulator, the service line and the fixtures, or test a well if your property truly has one. Call the number on this page to be connected with a local plumber in Alpharetta.
Water in Alpharetta
Alpharetta is an established north Fulton suburb and tech hub, with a revitalized downtown, the Avalon district and mostly 1980s to 2000s subdivisions. Fulton County supplies the city with Chattahoochee River water treated at the Tom Lowe plant in Johns Creek. The county repairs the line from the main to the meter; the line from the meter to the house is the owner's. The median home dates to 1996, which puts many original pressure regulators near the end of their working life.
Many Alpharetta homes also have lawn irrigation, and Fulton County's backflow program requires testable devices to be tested every year by a certified tester. A leaking or stuck irrigation valve can quietly pull pressure from the house, so it's worth checking alongside the regulator.
What to do right now
- Ask a neighbor. If their water is also weak, the cause may be a county main; Fulton's north Fulton drinking water emergency line is 770-640-3040.
- Check one fixture against another. A single weak faucet usually has a clogged aerator or cartridge.
- Watch the meter. Close every tap; if the dial moves, there's a leak past the meter.
- Confirm the main valve is fully open, especially after any recent plumbing work.
- If you have a well, check the pump breaker and the tank gauge before calling.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Weak at every fixture, water clear | Worn pressure regulator |
| Pressure suddenly very high, faucets banging | Regulator failed open |
| Meter moving with taps closed | Leak on the private service line, a toilet or irrigation |
| One shower weak | Clogged cartridge or shower head |
| Well home: pump runs nonstop | Leak, failed check valve or bad switch |
What affects the cost
- The cause. A regulator is usually a modest job; a buried line leak takes locating and digging.
- Surface over the leak. Lawn is easier than a driveway or patio.
- Irrigation. Many Alpharetta lots have sprinkler systems that need checking too.
- Permits. Alpharetta Community Development's Building and Inspections office handles permits.
