San Antonio Homeowners: Watch for These Plumbing Signals

Given the copper and galvanized steel in older homes, PEX in post-2000 builds systems common in San Antonio homes ā most installed during the 1950sā1990s in established neighborhoods ā these warning signs deserve immediate attention:
- āUnexplained increase in your water bill
- āSound of running water when all taps and fixtures are off

Local Plumbing Conditions in San Antonio
San Antonio draws its water supply primarily from the Edwards Aquifer, one of the most productive artesian aquifers in the United States, which delivers moderately hard water with calcium carbonate levels above 270 mg/L ā enough to cause significant scale accumulation in tank water heaters within two to three years without annual maintenance. The February 2021 freeze event was a watershed moment for the city: the SAWS system recorded over 3,000 service calls in a single week as copper pipes in uninsulated attics, exterior walls, and garages failed simultaneously across the metro. San Antonio has a split infrastructure profile: established neighborhoods retain copper and galvanized steel in older homes, PEX in post-2000 builds from the 1950sā1990s in established neighborhoods, while newer developments use current-standard materials ā and that mix, combined with expansive Taylor Marl clay ā extreme seasonal movement damages slabs and the undefined, means plumbing conditions and common failure modes vary significantly by address across the city.
