Water pooling at the base of the tank. Here's what to do about water heater leaks in San Antonio — including the local factors that change the advice.
Do this right now
Turn off the energy supply
Electric: switch the breaker off. Gas: turn the gas control to PILOT or OFF per the printed instructions.
Shut the cold water inlet
Turn the cold-water valve above the heater clockwise. This stops new water feeding the leak.
Drain pressure if safe
If the leak is small and the area is electrically safe, attach a hose to the drain valve and route it to a floor drain — only if you can do it without standing in water.
Contain and photograph
Towels and a bucket buy time. Photograph the leak location and any damage for insurance.

What makes water heater leaks different in San Antonio
- Very hard water from the Edwards Aquifer limestone — among the hardest in Texas — sediment accelerates tank corrosion, so heaters here often fail on the early side of their rated life.
- slab-on-grade ranch homes and Hill Country limestone-influenced builds — replacement logistics (attic vs. garage installs) change the job.
- In San Antonio, extreme South Texas heat with occasional hard winter freezes
- Hard-water scale is the silent killer of water heaters and fixtures here
