The Main Causes of Slab Leaks
Understanding why slab leaks happen can help you recognize your own risk factors and know when to have your plumbing checked.
Pipe Corrosion
Copper and galvanized steel pipes corrode over time, especially where water chemistry, oxygen exposure, or electrical currents in the ground accelerate the process. Corrosion eventually creates pinhole leaks.
Soil Movement
Dallas sits on expansive clay soil that swells when wet and shrinks when dry. That constant movement puts stress on rigid pipes running beneath the foundation, and over time it can crack or separate a joint.
Water Pressure
Consistently high water pressure puts extra strain on pipes and fittings, which can wear down weak points faster than normal usage would.
Abrasion During Installation
If a pipe was laid directly against gravel, rebar, or concrete without adequate protection, friction from ground shifting or water flow can wear through the pipe wall over years.
Poor Original Installation
Pipes installed with inadequate support, incorrect fittings, or without following code requirements are more prone to premature failure.
Age of the Plumbing System
Older homes with original copper or galvanized lines are statistically more likely to develop leaks simply because the pipe has had more time to corrode or wear.
