These pipes could consist of copper, PVC, or PEX and these pipes can become damaged from several factors over time, such as:
- Soil movements: The soil of Louisiana has tendencies to expand and shrink as moisture levels vary. This movement puts immense pressure on the pipes and can crack or break them.
- Corrosion: Corrosion weakens the pipe walls, thus making them prone to leaks.
- Tree roots: Tree roots may grow into and around the pipes, thereby causing damage and possible leaks.
- Ground settling: Slight shifting of the earth beneath can cause settling down of the foundation and in turn undue pressure and a leak on the pipes.

- Increased water bills: An abrupt and abnormal jump in your bill could be a definitive sign that you leak.
