Given the cast iron drains in older areas, copper supply, PEX in new builds systems common in Dallas homes — most installed during the 1950s–1980s in Oak Cliff and East Dallas, 2000s in outer suburbs — these warning signs deserve immediate attention:

• ✓Sound of running water when all taps and fixtures are off

Plumbing Facts Every Dallas Homeowner Should Understand

Dallas sits on Houston Black clay and Austin Chalk formations, soil types that swell by as much as 6 inches vertically when saturated and shrink dramatically during the dry summers that are common to North Texas. This soil movement is the primary driver of slab leaks in the Dallas metro — supply lines routed through or under concrete foundations are repeatedly flexed as the slab lifts and settles with seasonal moisture changes, eventually developing pinhole failures at stress points. Dallas has a split infrastructure profile: established neighborhoods retain cast iron drains in older areas, copper supply, PEX in new builds from the 1950s–1980s in Oak Cliff and East Dallas, 2000s in outer suburbs, while newer developments use current-standard materials — and that mix, combined with Austin Chalk and Houston Black clay — among the most expansive soils in Texas and the undefined, means plumbing conditions and common failure modes vary significantly by address across the city.
