Answer first
Knowing the main shutoff before an emergency is the highest-ROI five minutes a homeowner can spend.
01
Definition
What is this?
The main shutoff stops pressurized water entering the home from the meter or well system.
02
When to use
When does this apply?
Locate it at move-in, before vacation, and before any plumbing remodel.
03
Failure modes
What goes wrong?
Assuming the meter key is enough when you need an indoor valve. Painting over unlabeled valves. Never testing whether the valve still turns.
04
Proof
Why trust this guidance?
Hurst labels shutoffs on service visits when we can — because burst-pipe outcomes depend on it.
05
Action
What should you do next?
Find it today, tag it, and show everyone in the household.

FAQ
Meter or indoor?
Both can matter. Indoor valves stop house plumbing; meter valves are further upstream.
Valve will not turn?
Do not force to breakage — call us to repair or replace the shutoff.
Well homes?
Pressure tank and well controls add steps — ask us to walk your setup.
