How to Shut Off Water to an Outdoor Faucet
To shut off water to an outdoor faucet, find the indoor shutoff valve that feeds that faucet, turn the valve fully off, then open the outdoor faucet to drain the remaining water from the line.
Most outdoor faucets are controlled by a small shutoff valve inside the house, usually near the spot where the faucet comes through the wall. The job is simple once you find the right valve, but it helps to confirm you are shutting off the correct line before you leave the faucet for the season or start a repair.
Before you start: Match the part or procedure carefully before you start. Stop if the repair becomes unsafe or unclear.
Safety first
- Use caution in crawlspaces, basements, and utility areas where footing may be poor or lighting is limited.
- Do not force an old valve if the pipe twists or the valve body looks cracked or heavily corroded.
- Keep a bucket or towel nearby before opening any bleeder cap or draining the line.
- If shutting off the faucet is part of freeze protection, make sure the line is actually drained before cold weather hits.

Adjustable pliers
Use it for: Useful if the valve handle is stiff and needs a little extra grip.

Step-by-step fix
Step 1: Confirm this is the right task
- Use this how-to if you need to stop water to one outdoor faucet for winterizing, repair, or leak control.
- Check whether the outdoor faucet still runs when the handle is opened.
- Look inside the house on the same wall as the faucet for a dedicated shutoff valve on a small branch water line.
- If you already know the faucet has its own indoor shutoff, this is the right repair path.
If it works: You have confirmed you are trying to isolate an outdoor faucet, not shut off water to the whole house.
If it doesn’t: If you cannot find a dedicated valve, you may need to trace the pipe farther back or temporarily use the main house shutoff until you identify the correct branch line.
Stop if:
- Water is spraying, the pipe is split, or active leaking is soaking framing or finished surfaces.
- The only accessible valve is damaged, badly corroded, or already leaking from the stem or body.
Step 2: Find the shutoff valve that feeds the faucet
- Start in the basement, crawlspace, utility area, or under the nearest sink on the same side of the house as the outdoor faucet.
- Look for a small valve installed on the pipe leading toward the wall where the faucet exits outside.
- Follow the pipe by sight and touch if needed. Outdoor faucet shutoffs are often a few feet inside from the faucet location.
- Place a bucket or towel under the area if there is a small drain cap or bleeder on the valve.
If it works: You have located the valve most likely feeding the outdoor faucet.
If it doesn’t: If several valves are close together, leave the outdoor faucet closed for now and test one valve at a time in the next step until you identify the correct one.
Stop if:
- You find signs of hidden damage such as mold, rotted wood, heavy corrosion, or a slow leak inside the wall or ceiling below.
Step 3: Close the valve fully
- Turn the shutoff valve clockwise until it stops if it is a round-handle style.
- Turn the handle a quarter turn until it is perpendicular to the pipe if it is a lever-style valve.
- Do not force the valve hard once it reaches the closed position.
- If the handle is stiff, use pliers gently on the handle only if needed, with steady pressure instead of jerking it.
If it works: The valve is in the fully closed position.
If it doesn’t: If the valve will not move by hand, try a little more controlled pressure. If it still will not move, leave it alone and use the main shutoff until the valve can be repaired or replaced.
Stop if:
- The valve starts leaking around the stem, cracks, or feels like it may break.
- The pipe moves in the wall or framing when you try to turn the valve.
Step 4: Open the outdoor faucet and drain the line
- Go outside and open the outdoor faucet fully.
- Let the water run until the flow slows to a trickle and then stops.
- If the indoor shutoff has a small bleeder cap, open it carefully over your bucket or towel to drain trapped water from the section feeding the faucet.
- Leave the outdoor faucet open after draining if you are winterizing or leaving the line out of service.
If it works: The remaining water has drained from the faucet line and the faucet no longer has pressure behind it.
If it doesn’t: If water keeps running steadily, the wrong valve is closed or the shutoff is not sealing fully. Reopen the faucet outside, go back inside, and identify or test the correct valve.
Stop if:
- Water appears inside the house while draining the line.
- A bleeder cap will not reseal or starts leaking heavily.
Step 5: Check that the shutoff actually isolated the faucet
- With the outdoor faucet still open, wait a minute and confirm no steady flow returns.
- Turn the outdoor faucet off, then back on again to make sure pressure does not build back up.
- If there are multiple outdoor faucets, briefly test the nearby ones so you know whether this valve controls only one faucet or a larger branch.
If it works: The faucet stays off except for a brief leftover dribble, which means the line is isolated.
If it doesn’t: If pressure comes back, another line may be feeding that faucet or the shutoff valve may be passing water. Trace the piping farther back or use the main shutoff until the branch valve issue is fixed.
Stop if:
- More than one fixture loses water unexpectedly and you are no longer sure what this valve controls.
Step 6: Put the area back in a safe resting state
- Leave the indoor shutoff valve fully closed if the faucet needs to stay off.
- If you opened a bleeder cap, snug it back closed after draining unless your setup is meant to stay open for winterizing.
- Leave the outdoor faucet open if you are protecting the line from freezing, or close it if you only shut the water off for a short repair.
- Wipe up any spilled water and check the indoor valve and nearby pipe for drips over the next few minutes.
If it works: The faucet is shut off, the line is drained as needed, and there are no new leaks at the valve or nearby piping.
If it doesn’t: If you see drips at the shutoff after everything is set, the valve may need packing, repair, or replacement before you rely on it.
Stop if:
- The valve or pipe continues leaking after the shutoff is closed and the area dried off.
Verify the repair
- Open the outdoor faucet and confirm water does not continue flowing under pressure.
- Wait a minute with the faucet open to make sure pressure does not slowly return.
- Check the indoor shutoff valve and any bleeder cap for drips after the line is drained.
- If winterizing, leave the faucet in the intended final position and recheck after the next temperature drop or the next day.
FAQ
Where is the shutoff valve for an outdoor faucet usually located?
It is often inside the house on the pipe feeding the faucet, usually in a basement, crawlspace, utility room, or cabinet near the same exterior wall.
What if I cannot find a dedicated shutoff for the outdoor faucet?
Some homes do not have a separate shutoff for each outdoor faucet. In that case, you may need to trace the branch line farther back or use the main water shutoff until you can identify the right valve.
Should I leave the outdoor faucet open after shutting the water off?
Yes, if you are winterizing or trying to drain the line. Leaving it open helps any remaining water escape and reduces the chance of trapped pressure or freeze damage.
Why does water still come out after I shut the valve off?
A little leftover water is normal while the line drains. A steady flow usually means you closed the wrong valve or the shutoff is not sealing completely.
Can I use pliers on the shutoff valve handle?
Only gently and only if the handle is stiff. If the valve starts leaking, the pipe twists, or the handle feels like it may snap, stop and avoid forcing it.
