Local plumbing issues in San Antonio

01

Very hard water

Scale buildup shortens tank water heater life and calls for regular flushing or descaling of tankless units.

02

Slab leaks

Clay movement under slabs breaks hot and cold lines; warm spots on the floor are a common sign.

03

Drought watering rules

SAWS seasonal watering rules make leaking irrigation valves and backflow devices worth fixing quickly.

04

Winter Storm Uri

The February 2021 freeze burst pipes across San Antonio, where homes are built for heat and plumbing often runs through attics and exterior walls. Insulating vulnerable lines is a common follow-up.

05

Edwards Aquifer water

San Antonio draws much of its water from the Edwards Aquifer, a limestone source, which is why the water is so hard and why aquifer-stage watering rules apply in drought.
