Morrow water and sewer come from the Clayton County Water Authority, headquartered right in town, and CCWA's line ends at the meter. From the meter to the house, a leak is the owner's, and a plumber can confirm and pinpoint it. Call the number on this page to be connected with a local plumber in Morrow.

Morrow's housing grew up mostly in the 1960s and 1970s, before Southlake Mall and Clayton State shaped the town. The median home was built in 1971, and roughly 62% predate 1980. In those houses, original supply pipe, worn valves and decades-old service lines are where slow leaks usually start.
What to do now
- Turn off every faucet, appliance and irrigation zone.
- Read the CCWA meter and its leak indicator, wait an hour, then read it again.
- If it moved, close the main shutoff at the house and check again. If the meter is still moving, the leak is likely in the line from the meter.
- Drop food coloring in each toilet tank and look for color in the bowl after 15 minutes.
- Check the water heater and under each sink for drips.
- For a large leak in the street or a sewer backup, call CCWA at 770-960-5200, its number for after-hours water emergencies.
Symptom and likely cause
| Symptom | Likely cause |
|---|---|
| Meter moves with the main closed | Old service line leaking in the yard |
| Color in the toilet bowl | Flapper not sealing |
| Rust stain at a pipe joint | Corroded galvanized fitting |
| Water heater pan wet | Relief valve, fitting or aging tank |
| Floor soft near the tub | Supply or drain leak under the floor |
Cost factors
- Whether the problem is a quick toilet or valve fix, or a pipe hidden in a wall or yard
- How quickly the leak can be isolated in a house with older valves
- Access through a crawl space, slab or finished room
- Detection equipment needed
- The repair, and a city permit; Morrow's Planning and Economic Development Department issues plumbing permits, through Community Core or paper forms at City Hall
CCWA's service line runs from the main to the meter, and the customer owns the line from the meter to the house. CCWA also tests backflow devices at customer connections itself every year, and its lead and copper inventory portal lets residents look up their own property. When you call, you'll be connected with an independent plumber who works in Morrow and can walk you through what the search will involve. If the house still has its original main shutoff and it will not close fully, mention it; replacing that valve is often the first step before the rest of the search can go ahead.
