Know your shutoffs
before you need them.
A dripping supply line or a burst hose can flood a room in minutes. Take five minutes today to find these valves in your home — so a leak stays a puddle, not a disaster.
Tap a valve to see how it works
Every red marker is a shutoff you may have in your home. Click or tap one for a picture and simple steps.
A · Main house shutoff valve
□ Usually in the garage, where the pipe enters the wall- Turn the water off. Lever handle: turn it a quarter turn so it sits crosswise to the pipe. Wheel handle: turn clockwise until snug.
- This stops water to the whole house — use it when you can't tell where the leak is coming from, or the leak is inside a wall or ceiling.
- Open a faucet for a moment to let pressure drain, then call maintenance.
B · Fixture valves — toilets & sinks
□ Under sinks, behind toilets, behind the dishwasher- Turn the water off at that fixture: turn the small knob clockwise ("righty-tighty") until it stops.
- This stops water to just that fixture, so the rest of the house keeps working — perfect for a running toilet or a drip under the sink.
- Take a moment now to find these knobs at every toilet and sink, so you're not searching during a leak.
C · Washing machine valves
□ In the wall box behind or beside the washer- Turn the water off: turn both the hot and cold valves clockwise (or flip the single lever, if yours has one).
- Washer hoses are under pressure all the time — if a hose bursts or leaks, this stops it immediately.
- Leaving on a trip? Turning these off while you're away is cheap insurance.
D · Manobloc panel
□ Inside a cabinet in the laundry room or a closet- Turn the water off for the leaking fixture: find its labeled lever and turn it a quarter turn (crosswise to the pipe = off).
- Some homes have this panel instead of valves at each fixture — if you can't find a knob behind a toilet or under a sink, look here.
- Not sure which lever? Turn them all off, then call maintenance. Better dry than sorry.
E · Street shutoff at the water meter
□ Outside, in a box in the ground near the sidewalk- Turn the water off at the meter using a water meter key or a wrench — turn the valve until the water stops.
- This is your backup if the main valve in the garage is stuck, broken, or leaking itself.
- Lift the box lid carefully and use a flashlight — then call maintenance right away.
F · Irrigation / sprinkler valve
□ Outside, on the pipes near an exterior wall- Turn the water off: if the anti-siphon valve has a handle, turn it clockwise to close. Some models use a small screw or knob instead — also clockwise.
- This stops water to the sprinkler system only — use it for soggy spots in the yard, a geyser at a sprinkler head, or a dripping valve box.
- Then report it so the leak doesn't quietly run up the water bill.
G · Water heater
□ In the garage, sometimes a closet — a tall cylinder tank- Turn the water off at the valve on the cold water pipe on top of the tank. Lever handle: quarter turn, crosswise to the pipe. Round handle: turn clockwise until it stops.
- Can't tell which pipe is which? The cold inlet feels cool to the touch; the hot side feels warm. When in doubt, use the main house valve (A) instead.
- If the tank itself is leaking, also turn the heater off: gas models — turn the dial on the gas control box to OFF; electric models — flip the water heater breaker at the panel. A heating tank with no water in it can be damaged.
- Then call maintenance — water pooling under the tank means it needs attention right away.
Gas & electricity, in a pinch
Two more things worth knowing before there's a problem.
□ If you smell gas
- Open a window or door so gas can circulate outside and doesn't build up.
- Leave the area immediately.
- Call Southwest Gas at 1‑877‑860‑6020 once you're safely away.
⚡ If you lose power to outlets
- Check for a nearby GFI outlet — press the Reset button, then press Test to confirm it works.
- All bathrooms dead? Reset the GFI outlet in the garage — bathrooms often share it.
- Still out? Open the breaker panel. A breaker sitting out of line with the others has tripped: turn it fully off, then back on.
