Valves to find and label
Walk the house with a roll of tape and a marker. Label each valve and note it on a sketch of the house.
- Main shutoff, usually where the water line enters the basement or mechanical room, near the meter in many Parker homes
- Irrigation branch valve and its drain, often close to the main
- Water heater cold supply valve on top of the tank
- Each toilet's supply valve behind the bowl
- Sink valves in each bathroom and the kitchen
- Washer valves in the laundry box
- Refrigerator ice maker valve, often under the sink or in the basement ceiling below the kitchen
- Water softener bypass, if you have one
- Hose bib shutoffs inside the house for older-style spigots
Valve types and how to close them
| Valve type | How it looks | How to close |
|---|---|---|
| Quarter-turn ball valve | A lever handle | Turn the lever a quarter turn so it sits across the pipe |
| Gate or globe valve | A round wheel handle | Turn clockwise until snug; don't force a stuck one |
| Fixture stop | Small oval or round handle under sinks and toilets | Turn clockwise; push-pull styles push in |
| Curb stop | Underground valve near the street or property line, under a small cover | Requires a special key; often operated by your water provider |
Test them, gently
Start with the fixtures
Close and reopen each fixture valve. If one drips at the stem after moving it, note it for a plumber.
Test the main
Close it fully, open a faucet on the top floor and confirm the flow stops. Then reopen it slowly.
Fix what fails
Old gate valves sometimes won't close fully or start leaking once moved. A plumber can replace a stubborn main with a quarter-turn valve.

FAQs
Can I turn off the curb stop myself?
It usually requires a special key, and many water providers prefer to do it themselves. Call your water provider if the main shutoff inside fails.
Should I install an automatic shutoff valve?
Whole-house leak detection valves can close the main when sensors detect water or unusual flow. Some insurers offer discounts for them. Ask a plumber about installation near the main.
