You don't know where your main shutoff is (most common 'symptom'). Here's what to do about shutoff valves in San Antonio — including the local factors that change the advice.
Do this right now
Check the 4 usual spots
Where the water line enters the house (often garage or utility room), near the water heater, in a basement or crawlspace along the front wall, or in an exterior meter box near the street.
Identify the valve type
Gate valves have a round wheel (turn counterclockwise to open). Ball valves have a lever — parallel to the pipe is open, perpendicular is closed. Ball valves are more reliable.
Test it now, gently
Close it, check that a faucet stops, reopen. If a gate valve is stuck, don't force it — they snap. Note it for a pro to replace.
Label it
Tag it with a bright label and tell everyone in the household where it is. In an emergency, seconds matter.
Replace stuck valves proactively
Call (844) 699-1165. Swapping a frozen gate valve for a ball valve is a quick, cheap visit — and priceless during the next emergency.

What makes shutoff valves different in San Antonio

- In San Antonio, extreme South Texas heat with occasional hard winter freezes — knowing the shutoff before freeze season is essential.
- Clay soils over limestone bedrock — shifting plus rock-hard digging conditions
- Hard-water scale is the silent killer of water heaters and fixtures here
