Where is my main water shutoff valve, and how do I turn it off?
The short answer
In most Twin Cities homes it's in the basement on the wall facing the street, where the water line enters the house, right beside the water meter. A lever handle turns a quarter turn to shut off; a round wheel turns clockwise until it stops. Find it today and turn it once, before an emergency makes you find it.
Finding it
Start at the water meter. The main line comes through the foundation wall — almost always the wall closest to the street — and hits the meter within a few feet. There's a valve just before the meter and usually another just after. In a finished basement, look in the utility room, a closet on the street side, or behind an access panel. Slab homes and some townhomes put it in a utility closet, the garage, or near the water heater. Homes on a private well have the shutoff near the pressure tank instead.
Turning it off
- Ball valve (lever handle): turn it a quarter turn so the lever sits across the pipe instead of along it. That's off.
- Gate valve (round wheel): turn clockwise until it stops. Don't force it past that — old gate valves shear their stems, and a valve that spins freely without closing is broken.
- Two valves: use the one on the street side of the meter for a true shutoff. If it won't close, try the house side. If neither closes, the curb stop at the street belongs to the city.
Why this matters more in Minnesota
The burst-pipe season here is real, and the difference between a wet floor and a ruined basement is how fast the water stops. Older homes across Minneapolis, St. Paul, and the first-ring suburbs still have original gate valves from the 1950s and '60s. They corrode in the open position and fail exactly when you need them — the handle turns, nothing happens. If yours is a wheel-style valve that hasn't been closed in years, test it on a calm day. If it drips, sticks, or doesn't fully stop the water, replacing it with a quarter-turn ball valve is a small job that pays off the one time it counts.
Try it yourself, or call?
Worth trying first
- Find the valve and turn it off and on once — then show everyone in the house where it is
- Tag it: a bright zip tie or label so it's obvious in a panic
- Test it once a year; a valve that never moves is the one that seizes
Time to call
- The valve won't turn, spins freely, or leaks from the stem when you touch it
- It closes but water still flows — it's not sealing
- You want it replaced with a modern quarter-turn valve before winter
- You can't find one at all — some older homes have only the curb stop, and that's worth fixing
Common questions
Should I shut off the main when I go on vacation?
In winter, yes — it's the single best protection against coming home to a flood. Shut the main, then open a low faucet to relieve pressure. Leave the heat on at least 55°F so nothing already in the pipes freezes.
There's a valve on the meter itself. Can I use that?
The valve built into or right before the meter is typically the utility's. You can use it in an emergency, but if it breaks, the city has to fix it. Your own valve is the one on the house side of the meter — and if you don't have one, that's worth adding.
What's the curb stop?
A valve buried at the property line under a small metal cap in the yard or boulevard. It shuts off water from the street and requires a long key to operate. It belongs to the city; call them rather than opening it yourself.
