Dunwoody, GA
An Aging Public Grid and Layered Pipes Inside the House
Dunwoody's plumbing story has two layers, one under the street and one inside the walls. Water and sewer come from DeKalb County's Department of Watershed Management, and parts of that system are old. In July 2026, DeKalb said Dunwoody Knoll alone had seen 49 reported water main breaks from 1989 through 2024, caused in large part by pipe installed in the 1950s and 1970s. The county is now replacing about half a mile of main along Spalding Drive and Chamblee Dunwoody Road.
Main breaks and repairs can send pressure surges into houses. The IPC, which Georgia's plumbing code is based on, calls for a pressure-reducing valve where street pressure exceeds 80 psi, and a working regulator is the best protection an older Dunwoody house has against a surge finding its weakest fitting.
Main breaks are DeKalb's to repair. What they do to your house is not. Pressure surges, sediment and air in the lines hit the weakest fitting indoors, and in Dunwoody that fitting is often decades old.
Roswell 24/7 Plumbing answers emergencies in Dunwoody around the clock across 30338, 30346 and 30350, and handles the planned repairs these houses need.
Three Decades of Building, Three Kinds of Pipe
Dunwoody incorporated in 2008, but its neighborhoods were built out long before, mostly from the 1960s into the 1990s. Early ranches and split-levels gave way to two-story colonials, and the Colonial Williamsburg look around Dunwoody Village dates to the shopping center built there in the 1970s. Perimeter Mall opened in 1971 and pulled development toward 30346.
That long build window means one house can hold several generations of plumbing: galvanized steel from the original build, copper from a 1980s kitchen update, polybutylene in an addition, and PEX where something was repaired recently. Each ages differently. Galvanized rusts closed, polybutylene cracks at its fittings, and old copper can develop pinholes.
The practical takeaway is to identify what is actually in the walls before choosing a fix. Sometimes one section needs replacing. Sometimes the answer is a full repipe.

Close the house main and call. Pressure surges find the weakest fitting first.

Dunwoody Plumbing Problems and Where They Start
The source of a problem decides who fixes it.
| Problem | Usually starts at | Who handles it |
|---|---|---|
| Street flooding, no water on the block | DeKalb main break | DeKalb Watershed |
| Low pressure only at your house | Regulator, valve or old galvanized pipe | Plumber |
| Rusty water after a main break | Sediment stirred up in the main | Run cold taps, then plumber if it persists |
| Leak between meter and house | Your service line | Plumber |
| Sewage backing up indoors | Your lateral or the DeKalb main | Plumber first, DeKalb if the main is blocked |
For a soggy yard or pressure that never recovers, service line repair is often the fix. For drips you can hear but not see, leak detection finds them without opening more wall than needed.

What to Do Before We Arrive in Dunwoody
Steps that limit damage and help the diagnosis.
- Close the house main. It stops a burst whether or not the street main is also having problems.
- Check with a neighbor. No water on the whole street points to a DeKalb main break.
- Turn off the water heater if a hot line burst. Gas knob to Off or its breaker off.
- Look at the pipe at the water heater. Galvanized, copper, gray polybutylene or PEX. It tells the plumber what to bring.
- Photograph everything. For insurance, before cleanup starts.

Questions
Dunwoody Plumbing Questions
DeKalb County's Department of Watershed Management provides both. That means the meter and the public mains are DeKalb's responsibility, and everything on the house side of the meter is a plumbing repair. Water comes from the Chattahoochee through DeKalb's Scott Candler plant.
Yes, 24/7. That covers 30338 around Dunwoody Village and the neighborhoods along Chamblee Dunwoody Road, 30346 around Perimeter Center, and the parts of Dunwoody with 30350 and 30360 addresses.
Dunwoody's neighborhoods were built out over roughly 30 years, and many houses have been partly updated over time. It is common to find galvanized steel in one section, copper in another and polybutylene added in a 1980s addition or remodel. Each fails differently, which is why a full assessment beats patching one leak at a time.
Main breaks are DeKalb's to fix, but the pressure swings and sediment that follow can affect your house. After a break, run cold water to clear discoloration and check your pressure regulator and faucet aerators if flow drops.
If the house still has original galvanized supply, or you have had leaks in more than one place, usually yes. A planned repipe costs less than several emergency repairs and the water damage that comes with them.
