## Common plumbing problems in Charleston

Charleston combines some of the oldest housing in the country with low elevation, high water tables, and frequent tidal and rain flooding. That makes drains and sewer lines the center of many plumbing calls here.

- **Old sewer laterals**: Historic homes can have clay, cast-iron, or fiber sewer pipe that cracks, separates, and fills with roots from the city's mature trees.
- **Rain-related backups**: Heavy rain overloads parts of the sewer system, and water can back up through floor drains and low fixtures.
- **Flooding and high water**: Tidal and storm flooding stress drains and can push water into cleanouts and low plumbing.
- **Everyday repairs**: Water heaters, leaks, running toilets, and fixture failures, often in homes where access is tight.

## When to call a plumber in Charleston

- Drains back up during or after heavy rain
- Several drains are slow, or toilets gurgle
- Sewage smell inside or near the cleanout
- Your water heater is leaking or failing
- You're buying a historic home: get a sewer camera inspection
- After flooding, before using fixtures that were underwater

## Emergency plumbing guidance

1. **Shut off the water** at the fixture or the main shutoff.
2. **For a sewage backup,** stop using water and keep everyone away. If neighbors are backing up too, report it to Charleston Water System at (843) 727-6800.
3. **For a water main break or a leak on the utility's side,** call Charleston Water System at the same number.
4. **Don't use submerged fixtures** after flooding until they're checked.
5. **Photograph the damage** for your insurer. Sewer backup coverage usually requires a specific endorsement.

## Local plumbing considerations in Charleston

**Sewer overflows are a documented problem.** A February 2026 settlement between Charleston Waterkeeper and Charleston Water System cited at least 176 sewer overflows since 2015, more than half triggered by storms and routine rainfall, with West Ashley residents dealing with overflows for 10 to 20 years. CWS agreed to expedited inspections and repairs, closer inspection of West Ashley pipes, and a customer notification system for overflow events ([SELC](https://www.selc.org/news/latest-settlement-addresses-charleston-area-sewer-overflows/)).

**Help for private sewer lines may be coming.** As part of that settlement, CWS committed to recommending a grant program to reimburse homeowners for repairing or replacing certain leaking private sewer laterals, with proposed funding of $50,000 a year for five years. Leaking laterals let rainwater and groundwater into the sewer system, which contributes to the overflows. Ask CWS whether the program is active before you pay for a lateral replacement.

**Historic homes, historic pipes.** Many older Charleston homes have sewer laterals made of clay, cast iron, or fiber pipe, and the city's large trees send roots into any crack or loose joint. If you're buying an older home on the peninsula or in early suburbs, a sewer camera inspection before closing can save you a costly surprise.

**Water comes from Bushy Park Reservoir and the Edisto River.** CWS supplies roughly 400,000 people in the Charleston area ([USGS](https://www.usgs.gov/publications/characterization-water-quality-bushy-park-reservoir-south-carolina-2013-15)). For leaks in the street or at the meter, call CWS at (843) 727-6800; for leaks on your side of the meter, call a plumber.

## Plumbing questions from Charleston

**Why do my drains back up when it rains in Charleston?**

Heavy rain can overload parts of the sewer system, and cracked private laterals let rain and groundwater in. More than half of the 176 Charleston Water System overflows cited in a 2026 settlement were storm or rain triggered. A camera inspection shows whether your lateral is part of the problem.

**Will Charleston Water System help pay to fix my sewer line?**

Possibly. In a February 2026 settlement, CWS committed to recommending a homeowner grant program for repairing or replacing certain leaking private sewer laterals, proposed at $50,000 a year for five years. Contact CWS at (843) 727-6800 to ask whether it's active and who qualifies.

**Who is responsible for the sewer line from my house to the street?**

Generally the homeowner owns and maintains the private sewer lateral from the house to the public main, and CWS maintains the main. Ask CWS where its responsibility begins for your property.

**How much does a plumber cost in Charleston?**

There's no Charleston-specific price survey. HomeAdvisor's 2026 national data puts the average plumber visit at $341, with most between $182 and $501. Sewer line repairs typically run $1,390 to $5,300, more for long, deep, or hard-to-reach lines.

**How do I check a plumber's license?**

South Carolina requires a license for residential plumbing work over $500, issued by the SC Residential Builders Commission. Look up any plumber by name or license number for free on the SC Department of Labor, Licensing and Regulation's online verification site.
