Why do slab leaks happen in South Fulton homes?
Slab leaks are not unique to this area, but several local factors make them more likely.
- Red clay. Clay swells in wet weather and shrinks in dry spells. The slab and the pipes beneath it can shift slightly over time.
- Pipe age and material. Many homes from the 1990s and 2000s have copper lines that can corrode or develop pinholes. Some 1990s homes may still have polybutylene, a gray plastic pipe used until the mid-1990s that is known for failures, so identifying the pipe type matters.
- Abrasion. Pipes can rub against concrete or gravel as they expand and contract with hot and cold water.
- High water pressure. Constant strain on lines and joints.
- Construction damage. A nick or a poor joint made when the home was built can fail much later.
Not every home here has supply lines under the slab. Some run them through the attic or walls, with only drains under the floor. A plumber can tell what your house has.
