Plumber in Mableton and Riverview Georgia's newer city and Smyrna's riverfront, next door.
Mableton voted to become a city in November 2022, more than a century after an earlier town government dissolved in 1916 following a flood that overwhelmed its sewer system. Next door, Smyrna's Riverview Landing turned an 82-acre former industrial site along the Chattahoochee into new homes and apartments. Old and new plumbing, and river weather, define this corner of south Cobb.
Short answer: In Mableton, plumbing needs range from older homes with aging supply lines and sewer laterals to new construction. Along the river at Riverview Landing, newer homes and apartments sit near the Chattahoochee, which flooded The Eddy at Riverview during Helene in 2024. Most Mableton homes are on the Cobb County Water System (Emergency Dispatch 770-419-6201); check your bill. Call (470) 357-0172 any hour.

River weather, old homes and new construction
This part of south Cobb mixes some of the area's oldest settled history with some of its newest construction, all near the Chattahoochee River.
Older Mableton homes
Mableton was settled in the 1840s and grew around the railroad that arrived in 1881. Much of its housing was built during later waves of suburban growth. As with older homes anywhere in Cobb County, expect aging galvanized or copper supply lines, cast iron drains, older sewer laterals and water heaters near the end of their life. See repiping and sewer line repair.
New construction
New subdivisions, townhomes and apartments have modern materials, but new homes still leak: a fitting that was not fully crimped, a shower pan that was not sealed, or a water heater installed without an expansion tank. If your home is under a builder warranty, check it first for early leaks.
Riverfront living
Riverview Landing sits along the Chattahoochee on a former industrial site, with single-family homes, The Eddy apartments and a linear riverfront park. When Helene's rain pushed the river over its banks in September 2024, The Eddy at Riverview flooded and Riverview Road closed between South Cobb Drive and Veterans Memorial. After any flood, water heaters, electrical connections and sewer cleanouts that were underwater should be checked before use, and floodwater can push debris into drains.
Sewers, then and now
Mableton's first town government was dissolved in 1916 after a flood overwhelmed its sewer system and tax disputes followed. Today, public sewers are maintained by the utility, but the lateral from your house to the main is still yours, and heavy storms remain the time backups are most likely. A backwater valve can help protect low drains in some homes.

Storm and flood readiness for your plumbing
- Know your cleanout. During a backup, a plumber can clear the line faster from an outside cleanout.
- Ask about a backwater valve if you have drains below street level that have backed up during storms.
- Test your sump pump before storm season if you have one.
- After a flood, do not relight a gas water heater or use one whose controls were underwater until it is checked.
- Disinfect and flush lines and fixtures that floodwater reached, following public health guidance.
- Follow boil water advisories from your utility until they are lifted, then flush taps and replace refrigerator filters.
- Check flood and sewer backup coverage with your insurance agent; standard policies often exclude both.

Plumbing questions in Mableton & Riverview
Is Mableton on Cobb County water?
Most of Mableton is served by the Cobb County Water System. Check your bill, especially near the Smyrna line.
When did Mableton become a city?
Voters approved cityhood on November 8, 2022, and the first mayor in over a century took office in 2023.
What should I do with my water heater after a flood?
Do not use or relight it until it has been checked. Gas controls and electrical parts that were underwater often need replacement.
Why does my basement drain back up during heavy rain?
Storms can overload sewer lines. A partially blocked lateral or a low drain without a backwater valve makes backups more likely.

Who do I call for a water main break in Mableton?
Cobb County Water System Emergency Dispatch at 770-419-6201.
Do you serve new construction in Mableton?
