Here's a two-minute task that can save you thousands: find your main water shut-off, and make sure it works — today, while nothing's wrong. In an emergency, it's the difference between a wet towel and a flooded house.
Where to look
Your main shut-off is usually where the water line enters your home. Common spots in San Diego homes:
- In the garage, along the wall nearest the street
- On an exterior wall, often near a hose bib
- In a ground box near the street or sidewalk (the water meter), with a valve you may need a meter key to turn
Two kinds of valves
- Ball valve: a lever. Water's on when the lever is in line with the pipe; turn it a quarter-turn (perpendicular) to shut off.
- Gate valve: a round wheel. Turn it clockwise (righty-tighty) several times to close. These are the ones that love to seize up over time.
Test it now
Turn it off, then open a faucet to confirm the water stops. Turn it back on. If it's stiff, stuck, or leaks when you move it — that's a problem to fix before an emergency, not during one. Hard-water scale is notorious for freezing old valves.
Bonus: know your fixture valves too
Each toilet and most sinks have their own small shut-off (angle stop) so you can isolate one fixture without killing water to the whole house. Worth knowing where those are, too.
If your main valve won't turn or weeps when you test it, don't force it. give K2 a call and we'll replace it with one you can trust when it counts.
