Dunwoody's water comes from DeKalb County Watershed Management, and the report text we reviewed doesn't state hardness, so a tap test should come before any softener. With roughly 28% of homes built in the 1970s, check the plumbing too. Call the number on this page to be connected with a local plumber in Dunwoody.
The City of Dunwoody lists DeKalb County Watershed Management as its water provider and runs no water system of its own. DeKalb treats Chattahoochee River water, drawn upstream of Atlanta, at the Scott Candler plant. Hardness isn't stated in the report text reviewed. About 44% of Dunwoody homes were built before 1980, and the 1970s alone account for roughly 28%, so many houses around Dunwoody Village have original supply lines and have been through several water heaters.
What to do now
- Test hardness. A strip at a cold tap or a plumber's meter tells you whether a softener has any job to do.
- Identify your service line. DeKalb lists customer-side line material as unknown and asks owners to identify it. Know what you have before picking a filter.
- Separate hot from cold. Symptoms on hot water only usually mean the water heater.
- Look at existing equipment. A softener or filter added by a past owner may be overdue for service.
- Plan the permit. Dunwoody's single-trade component permits cover stand-alone jobs such as water heater replacements and plumbing repairs, and work can't start until the permit is issued.
Symptom and likely cause
| Symptom | Likely cause |
|---|---|
| Rust at the first draw, clearing after a minute | Corroding galvanized supply pipe |
| Weak flow at several fixtures | Narrowed old pipe or a failing pressure regulator |
| White crust on fixtures | Hardness minerals; confirm by test |
| Disinfectant smell | Normal treatment; a carbon filter helps |
| Popping water heater | Sediment or scale in the tank |
Cost factors
- Treatment alone versus treatment plus pipe or heater work
- Pipe condition where equipment ties in
- Drain and power near the main
- Permit for the job
- Recurring salt or cartridges
DeKalb maintains the line from the main through the meter; the homeowner owns the rest. Homes with a separate irrigation tap need a backflow assembly tested annually.
In practice, many Dunwoody calls end with a smaller job than expected: a carbon filter for taste, a heater flush, or a service line replacement that clears up the color for good. A softener earns its place only when the test shows real hardness and the household is tired of scrubbing scale. If that's your situation, size it to the measured number and your family's water use rather than to a sales chart, and make sure it has a bypass so the plumber can service it later without shutting off the house.
