Rex is unincorporated, so Clayton County Water Authority supplies water and Clayton County issues permits. CCWA's service line ends at the meter, and the line from the meter to the house, including under the slab, belongs to the homeowner. Call the number on this page to be connected with a local plumber in Rex.

Who owns the pipe under my Rex home?
You do. Clayton County Water Authority serves the whole county, including unincorporated Rex. CCWA describes its service line as running from the water main to the meter; the line from the meter to the house is the customer's. Any leak beyond the meter, under the slab or inside the walls is a private plumbing repair. If the leak is at the meter or in the street, CCWA's customer service line also takes after-hours calls for large leaks.
CCWA has completed a service line material inventory and offers a lookup portal where you can see how your line is recorded.
How old are homes around Rex?
Rex is centered on the historic Rex Mill and Rex Village in eastern Clayton County. Census survey figures via Point2Homes put the median year built at 1995, with about 20% of homes built before 1980. That means most houses are slab-era subdivision homes from the 1980s through 2000s. In the older ones, copper under the slab is old enough to wear; in newer ones, leaks usually start at a buried fitting or where pipe was damaged during construction.
Where do permits come from?
Because Rex has no city government, Clayton County Community Development's building permit section handles building, mechanical, electrical and plumbing permits for remodels, repairs and new construction, from its office in Jonesboro. A reroute or replacement of a water line will typically go through that office, and the plumber usually files it.
Ask the plumber whether the leak is on a branch or the main supply. A branch can often be bypassed with a short new run through a wall; a leak on the main may make a fuller reroute worthwhile.
A Rex note
Do a meter test before calling: turn off every fixture, appliance and irrigation zone, note the reading, wait fifteen minutes and read it again. If it changed and the toilets pass a food-coloring test, a slab leak is worth checking. Clear access to the water heater before the plumber arrives. If water is pooling anywhere, close the main shutoff first and say so when you call.
