Why Shutoff Valves Matter

If a supply line bursts, a toilet overflows, a faucet leaks, or an appliance water line starts dripping, a working shutoff valve can help stop the water before it causes more damage.

A fixture shutoff may let you turn off water to one area while the rest of the home still has water.

Examples:

• A toilet shutoff can stop water to the toilet
• A sink shutoff can stop water to a faucet
• A washing machine valve can stop water to the washer hoses
• A refrigerator shutoff can stop water to the ice maker or water dispenser
• A water heater shutoff can stop water feeding the unit

Common Shutoff Valve Problems

Shutoff valves can wear out over time, especially if they have not been used in years.

Common issues include:

• Valve is stuck
• Valve will not turn
• Valve is corroded
• Valve leaks when touched
• Valve does not fully shut off water
• Handle is broken or missing
• Valve is hard to reach
• Valve drips after being turned
• Old supply line or connection is brittle

If a valve looks old, rusty, wet, or difficult to turn, be careful. Forcing it may make the leak worse or cause the valve to fail.

Fixture and Appliance Shutoff Valves

Shutoff valves are small but important parts of your plumbing system. They allow water to be turned off to a specific fixture or appliance without shutting off water to the entire home.

Knowing where these valves are can help limit damage if something starts leaking, spraying, or backing up.

What Is a Shutoff Valve?

A shutoff valve controls water flow to a fixture or appliance.

Common places to find shutoff valves include:

• Under sinks
• Behind toilets
• Near the washing machine
• Behind or beside the refrigerator
• Near the dishwasher connection
• At the water heater
• Near ice maker lines
• Near some exterior hose bibs
• Near filtration systems or other plumbing equipment

These valves can be very helpful during a leak or repair.

What You Can Check

It is helpful to know where your shutoff valves are before there is an emergency.

Look around your home and note where shutoffs are located for:

• Toilets
• Bathroom sinks
• Kitchen sink
• Washing machine
• Refrigerator water line
• Water heater
• Dishwasher connection
• Main water shutoff

You do not have to turn every valve, especially if it looks old or corroded. Just knowing where it is can help in an urgent situation.

When Not to Force a Valve

Do not force a shutoff valve if:

• It is rusty or corroded
• It is leaking
• The handle feels stuck
• The pipe moves when you touch it
• The valve looks cracked or damaged
• You are not sure which valve it controls
• The area around it is already wet

A stuck valve may need repair or replacement before it can be safely used.

Appliance Shutoff Valves

Appliances with water connections often have shutoff valves.

These may include:

• Refrigerator ice maker or water dispenser
• Dishwasher
• Washing machine
• Water heater
• Filtration system

If an appliance is leaking, the shutoff valve may help stop the water while you wait for service. If you cannot find the shutoff or it will not turn, you may need to use the main water shutoff.
