The city runs a main line down your street, and a smaller line branches off to feed your house. Before it gets to you, it passes through a meter, usually a round cast-iron lid set in the ground near the curb or sidewalk.Lift that lid and you'll see the meter and a shutoff valve. You can technically stop the water here, but a lot of cities would rather you leave this one alone. Think of the curb valve as a last resort. Its real value is that it points you toward the line running into your house."},{"number":2,"title":"Step 2: Trace the Line From the Meter Into the House","text":"Here's the trick that saves you a frantic search. Stand at the meter and picture a straight line running from it to your house. The supply line almost always takes that shot, passing through the foundation and popping up on the wall just inside.Once it's through the wall, there should be another valve close by. It usually sits right before the pressure regulator, the bell-shaped fitting that keeps your house pressure in check. That indoor valve is the one you actually want for shutting the water off."},{"number":3,"title":"Step 3: Check Behind an Access Panel in Finished Rooms","text":"Sometimes that straight line lands in a finished room. In this example, a bedroom sits on the other side of the meter wall, so there's no bare pipe in view. Don't assume the valve isn't there.Look for a removable access panel on the wall or up on the ceiling. Pop it open and you'll usually find the shutoff valve and the pressure regulator tucked inside. Builders leave these panels on purpose so the valve stays reachable without tearing into drywall."},{"number":4,"title":"Step 4: Look in the Basement or Mechanical Room","text":"If your line runs into an unfinished basement, your job gets easier. The water comes right through the foundation into the mechanical room, and the main shutoff valve sits out in the open along that wall, often near the water heater and pressure tank.Follow the incoming copper or PEX line from where it enters the wall. The first valve you hit is your main shutoff. Give it a good look now so you can grab it in the dark if you have to."},{"number":5,"title":"Step 5: Know Which Valve Type You Have","text":"Before you turn anything, look at the valve itself. There are two you'll run into. The most common is the handle or lever style, a straight arm you swing a quarter turn. It's quick and it's obvious which way it goes.The older style is a round knob or wheel you spin, more like a garden spigot. It takes several turns to close all the way. Knowing which one you're dealing with tells you exactly how to shut it, so there's no fumbling when it counts."},{"number":6,"title":"Step 6: Close the Valve","text":"For a lever valve, turn the handle until it sits perpendicular to the pipe. Picture it this way. When the handle lines up with the pipe, water is flowing. When it crosses the pipe, the water is stopped. In line means on, across means off.For a knob valve, it's righty-tighty. Turn it clockwise until it won't budge anymore, and that means it's closed. If the knob is stiff and won't move by hand, an adjustable wrench or a pair of pliers gives you the leverage to break it loose without stripping it."},{"number":7,"title":"Step 7: Exercise the Valve Before You Need It","text":"Don't wait for a flood to find out your valve is seized. Go close it once, right now, while nothing is wrong. A lot of older valves lock up from years of sitting untouched, and a valve you can't turn is no help at all.If it fights you, keep a wrench or pliers on hand to work it free. And if yours is an old knob that's hard to move, ask your plumber to swap it for a lever valve the next time they're out. That small upgrade turns a two-minute struggle into a one-second flick."}],"recipe":null,"lastUpdated":"2026-07-20T17:59:18.174Z","published":"2026-07-20T17:57:43.715Z","license":"CC BY 4.0.
