Drains & sewer in South Carolina: what to know
Red clay and mature trees in Columbia and Greenville crack and fill older laterals with roots, and Charleston Water System and Columbia Water serve those cities.
A camera inspection shows whether a recurring clog is roots or a broken pipe, and a backwater valve helps in flood-prone areas.
- Climate
- Freezes are uncommon in most of South Carolina, but when a hard freeze does arrive, homes built for warm weather, with pipes in attics and exterior walls, are the ones that split.
- Typical foundations
- Crawl spaces and slabs are the common foundations, and coastal homes face salt-air corrosion. Most common: crawl spaces, concrete slabs.
Drains & sewer services
Drain cleaning
If one fixture is slow, the clog is usually in that fixture's branch line. If several drains back up at once, or the basement floor drain fills when you run the washer, the main sewer line is blocked and needs a larger cable or a jetter.
Hydro jetting
Hydro jetting cleans the full width of a drain pipe with high-pressure water, washing out grease, scale and fine roots that a cable only punches a hole through. It works best on sound pipe and is usually done after a camera inspection confirms the pipe can take it.
Sewer camera inspection
A sewer camera inspection runs a waterproof camera through the line from your house to the city main and records what it finds: roots, cracks, sags, offset joints or collapsed pipe. It's the best way to decide between cleaning, spot repair and replacement.
Sewer line repair
A damaged sewer line can be fixed with a spot repair, a trenchless liner, pipe bursting or an open-trench replacement. Which one fits depends on what the camera shows, how deep the pipe is, and what's on top of it, such as a driveway, trees or landscaping.
