The Short Answer
Where to look: where the water line enters the house, usually on the side facing the water meter. In a cold climate like Spokane’s, that’s typically inside: a basement wall, crawl space, garage or utility room.
How to close it: turn a round wheel handle (gate valve) clockwise until it stops, or turn a lever handle (ball valve) a quarter turn so it sits across the pipe.
If it won’t move: don’t force it with a pipe wrench. The water can be shut off at the meter, or the water provider can help.
Test it once a year: valves that never move tend to seize. A plumber can replace one that sticks, leaks or won’t fully close.

When a pipe splits during a Spokane cold snap or a water heater starts leaking, the main water shutoff is the single most important valve in the house. Closing it stops the damage in seconds, but only if someone knows where it is and the valve actually turns. This guide covers where to find the main valve in Spokane-area homes, the difference between gate and ball valves, how to shut the water off step by step, when the meter and curb box come into play, the smaller fixture shutoffs, and why the valve deserves a yearly test.

Why Every Spokane Household Should Know Where It Is
Before freezing weather, the City of Spokane Water Department asks residents to take a moment to find their home’s water shut-off valves and the areas each one controls, because shutting off the water quickly can limit damage from a leak. The city also advises confirming that the shutoff works before thawing a frozen pipe, so the house doesn’t flood when the ice melts.

Where to Find the Main Water Shutoff Valve
The main valve is usually where the water pipe enters the house, on the same side as the water meter, so the front of the house is a good place to start. In cooler climates it’s commonly inside the house or foundation; in warmer climates it’s more often outdoors. Common spots include:
- Basement: on the wall facing the street, often low and near where the line comes through the foundation
- Crawl space: near the access hatch or the front foundation wall
- Garage or outdoors by the foundation: often near the front outdoor faucet
- Closet or utility room closest to the meter
- Buried access box: common for homes on a slab with no basement or crawl space

Gate Valve vs. Ball Valve
Most main shutoffs are one of two types. Gate valves were traditionally used on main water lines; ball valves use a quarter-turn design.
| Gate valve | Ball valve | |
|---|---|---|
| Handle | Round wheel or knob, several turns | Lever, quarter turn |
| To shut off | Turn clockwise until it stops | Turn the lever so it sits perpendicular to the pipe |
| Open position | Turned fully counterclockwise | Lever lines up with the pipe |
| Reliability | More prone to seizing; should be exercised regularly | Fewer moving parts; described as more reliable with a longer life |
| Warning signs | Handle spins without closing, or water still trickles through | Hard to turn, seepage, or green or white buildup on the body |

How to Shut Off the Water, Step by Step
- Find the valve where the main line enters the house. Keep a flashlight handy for basements and crawl spaces.
- Close it. Gate valve: clockwise until it stops. Ball valve: a quarter turn until the lever is across the pipe. There should be no need to crank down hard.
- Open a faucet to relieve pressure in the lines. A faucet on the bottom floor drains more of the water still in the pipes.
- Turn off power to an electric water heater. The Home Depot notes that running an electric heater without water can burn out the elements; check the manual first.
- Confirm the water has stopped by checking that the open faucet slows to nothing.

The Water Meter and Curb Box
Most homes also have a shutoff outside, near the street and below the frost line, often hidden in landscaping. This Old House describes it as one more line of defense that local officials operate with a special wrench, so it’s worth knowing where it is. Many meter boxes need a meter key to open, and a “curb key” (a large metal T with a notched end) fits over a valve that looks like it’s missing its handle.

Rules for who may operate the meter valve differ by utility. Seattle Public Utilities, for example, tells customers to generally use their home valve, and only certain meter valves can be turned by customers; older meters need a special tool and are handled by utility crews. Before touching the meter valve, check with the local water provider. City of Spokane water customers can find the Water Department’s contact details on the city website.

Know the Fixture Shutoffs Too
Toilets, sinks and water heaters usually have their own small shutoff at the base of the supply line, called a stop. An angle stop has its outlet at 90 degrees and is used where the supply comes out of the wall; a straight stop is common where the line comes up through the floor. Closing one lets the rest of the house keep running water while a single fixture is repaired. Source: The Home Depot – Types of Water Shut-Off Valves · Checked: November 7, 2026
Those small valves and their connections matter for leaks, too. The U.S. Department of Energy’s Building America Solution Center lists toilet angle valves and faucet supply hoses among common leak points, and notes that household leaks can waste more than 10,000 gallons of water a year in an average home.

Test the Main Valve Once a Year
The Home Depot recommends exercising shutoff valves periodically so they keep working, especially gate valves, which are more prone to seizing. Once a year, for example each fall before the first hard freeze, is an easy schedule to remember: close the valve, confirm the water stops, then open it again. Source: The Home Depot · Checked: November 7, 2026
Signs the valve needs attention, according to This Old House: it’s hard to turn, it doesn’t fully stop the water, it leaks around the stem or body, or it shows corrosion or green or white mineral buildup from seepage. Richard Trethewey recommends replacing older gate valves with ball valves. Replacing a main valve typically requires the water utility to shut off service at the street, and homes without a working main shutoff should have one installed.

Common Questions
Which way does the main water valve turn to shut off?
Clockwise for a wheel-handle gate valve, until it stops. For a lever-handle ball valve, a quarter turn so the lever sits across the pipe; when the lever lines up with the pipe, the water is on.
Does shutting off the main drain the water heater?
No. City of Seattle preparedness guidance notes that closing the main house valve keeps the water already inside the house, including the water heater and toilet tanks, from draining away. Only the pressure is relieved when a faucet is opened.
What if the house has no main shutoff valve?
Both Seattle Public Utilities and City of Bellevue Utilities recommend having one installed by a plumber. Until then, the only way to stop the water is at the meter, which may need a special tool or the water provider.
Can the water department shut off the water at the street?
The street-side valve is operated by the utility with a special wrench, according to This Old House. City of Spokane water customers can contact the City Water Department; homes served by another water district should contact that provider.
