Water spraying or gushing from a pipe, wall, ceiling, or under a sink. Here's what to do about burst pipes in San Antonio — including the local factors that change the advice.
Do this right now
Close the nearest valve first
If the burst is at a toilet, sink, or appliance, turn its small stop valve clockwise. This can stop the flow in seconds.
Shut off the main water valve
Can't find a local valve — or the break is in a wall? Close the main shutoff for the whole house now. Don't wait until you 'find' it; close first, label later.
Kill power near the water
If water is near outlets, appliances, or the breaker panel, stay out of standing water and don't touch breakers with wet hands.
Drain pressure safely
After the main is off, open a cold faucet at the lowest point in the house to relieve line pressure — only if it creates no new hazard.

What makes burst pipes different in San Antonio
- In San Antonio, the 2021 freeze burst pipes across San Antonio, especially in attics and exterior walls
- Homes here are often slab-on-grade ranch homes and Hill Country limestone-influenced builds — which changes where pipes run and how hard they are to reach.
- Clay soils over limestone bedrock — shifting plus rock-hard digging conditions
- Hard-water scale is the silent killer of water heaters and fixtures here
