Most Marietta sump pump calls trace back to a sticking float, a leaking check valve, a power problem or a worn-out motor. A plumber can tell you whether to repair, replace or add a backup, and keep the discharge out of the sewer that Marietta Water runs.

Marietta homes and utilities
Marietta is the historic Cobb County seat built around Marietta Square. Census survey figures put the median home at 1987, with about a third built before 1980. Older houses near the Square often sit on crawl spaces where a pump was added later; homes from the 1980s and 1990s may still run the original unit.
Marietta Water, the city utility, provides both water and sewer inside the city. Some Marietta-addressed homes outside city limits are on Cobb County Water System instead, so check your bill. Either way, the sanitary sewer is built for household wastewater, and a sump line plumbed into a cleanout or laundry drain should be rerouted to the yard.
Marietta Water runs its own cross-connection program. It rates services by hazard, specifies the device, and requires testable backflow devices to be tested every year by a certified tester with results sent to the utility. That matters if you're weighing a water-powered backup.
Options compared
| Option | Best when | Marietta note |
|---|---|---|
| Repair (float, switch, check valve) | The motor still runs strong | Common on pumps under ten years old |
| Replace the pump | Motor is noisy, overheating or corroded | Older crawl spaces near the Square often need this |
| Battery backup | Outages during storms | No water connection involved |
| Water-powered backup | You want no battery to maintain | Marietta Water's annual backflow testing likely applies |
| High-water alarm | The pit is out of sight | Worth it for a finished basement |
Signs it's failing
- The pit overflows during a storm while the pump stays off
- It runs and runs, but the outdoor pipe is dry
- Clicking on and off in short bursts
- Water rushing back into the pit after it stops
When to schedule it
Test the pump before the wet months rather than during a downpour. City of Marietta Building Inspections issues plumbing permits for changes to existing buildings, so if the work goes past swapping a pump, the plumber can say whether one is needed. For addresses on Cobb County water outside the city, the county may handle permits instead. When you call, say where the pit is, what the pump is doing and whether water is rising, and shut off the pump's circuit if water is near the outlet.
