Leaky Outdoor Faucet? How to Fix It (Hose Bib Repair)

Why Outdoor Faucets Leak

An outdoor faucet — also called a hose bib, sillcock, or spigot — lives a hard life. It sits outside through freezing winters, blazing summers, and months of being yanked on by garden hoses. Sooner or later, most of them start to drip. A spout that drips once every few seconds can waste a surprising amount of water over a season, and a leak around the handle can rot the siding or trim behind it.

The good news: most outdoor faucet leaks are simple washer or packing problems you can fix yourself in under an hour with basic hand tools. This guide walks you through diagnosing the leak, shutting off the water safely, and repairing both common leak types — a dripping spout and a weeping handle.

Figure Out Where the Leak Is Coming From

Before you grab a wrench, spend a minute identifying the leak. The repair is different depending on the source:

• Drip from the spout when the faucet is off: the rubber bibb washer inside is worn, cracked, or has debris stuck under it. This is the most common leak.
• Water seeping around the handle or stem: the packing nut is loose or the packing material around the stem has dried out.
• Water leaking from behind the faucet, inside the wall: the pipe connection or the faucet body itself may be cracked — often from freezing. This one usually needs a plumber.
• Leak only when a hose is attached and the water is on: check the hose washer and the connection first; the faucet itself may be fine.

Before You Start: Shut Off the Water

Safety first: always shut off the water supply to the outdoor faucet before taking it apart. Most homes have an interior shutoff valve for each outdoor spigot — look in the basement, crawl space, or utility room on the wall directly behind the faucet. Turn it clockwise to close it.

• After closing the shutoff, open the outdoor faucet to drain residual water and relieve pressure.
• Keep a bucket and old towels under the work area. Even with the supply off, water trapped in the line will spill when you remove parts.
• If you cannot find an interior shutoff for the faucet, shut off the main water supply to the house. If you are not sure where that is, read our guide on finding your main water shutoff valve before you continue.
• Never force a stuck shutoff valve with excessive leverage — old gate valves can snap. If the valve will not turn, stop and call a plumber.

Tools and Parts You’ll Need

• Adjustable wrench (or two — one to hold, one to turn)
• Phillips and flathead screwdrivers
• Replacement bibb washers (assorted pack from any hardware store — bring the old one to match size)
• Packing string or PTFE packing (for handle leaks)
• Penetrating oil (for corroded nuts)
• Bucket, towels, and a small container for screws
• Plumber’s grease (silicone-based) for reassembly

How to Fix a Hose Bib That Drips From the Spout

A spout drip almost always means the bibb washer at the end of the stem is worn. Here is the full repair:

Step 1: Remove the handle

With the water off and the line drained, remove the screw in the center of the handle (it may be hidden under a decorative cap — pry the cap off gently with a flathead screwdriver). Pull the handle straight off the stem. If it is stuck from corrosion, spray a little penetrating oil around the stem and wait a few minutes.

Step 2: Loosen the packing nut

The packing nut is the hex nut directly behind the handle, where the stem enters the faucet body. Hold the faucet body steady with one wrench and loosen the packing nut with the other, turning counterclockwise. Back it off enough to free the stem.

Step 3: Unscrew and remove the stem

Turn the stem counterclockwise as if you were opening the faucet, and keep turning until the whole stem assembly slides out of the body. Note the order of the parts as they come out — a quick phone photo helps at reassembly.

Step 4: Replace the bibb washer

At the bottom end of the stem you will see a small rubber washer held by a brass screw. Remove the screw, swap in a new washer of the same size and thickness, and tighten the screw snugly. This washer is what seals against the valve seat to stop the drip — a cracked or flattened washer is the cause of your leak.

Step 5: Check the valve seat

Look inside the faucet body where the washer seats. If the seat feels rough or has mineral buildup, clean it gently with a cloth. A badly pitted seat will chew up a new washer quickly; in that case you can reface it with an inexpensive seat-dressing tool, or replace the faucet.

Step 6: Reassemble

Apply a thin smear of plumber’s grease to the stem threads and the new washer, slide the stem back in, tighten the packing nut, and reattach the handle. Do not overtighten the packing nut — snug is enough, and you can tighten slightly more later if the handle weeps.

How to Fix a Leak Around the Handle

If water seeps from around the stem when the faucet is on, the packing is the problem. Often the fix is a simple tightening:

1. With the water on and the faucet open, tighten the packing nut clockwise about a quarter turn. In many cases this recompresses the packing and stops the weep immediately.
2. If it still leaks, shut off the water, remove the handle and packing nut, and pull out the old packing material from around the stem.
3. Wrap new PTFE packing string or graphite packing around the stem, following the manufacturer’s direction, then reinstall the packing nut and handle.
4. Turn the water back on and check. Tighten the nut in small increments until the seep stops — overtightening makes the handle hard to turn and wears the packing faster.

What If You Have a Frost-Free Faucet?

Many newer homes have frost-free (freeze-proof) sillcocks, recognizable by their long stem — the shutoff point sits 6 to 12 inches inside the warm wall. They can still develop washer leaks, and the repair is the same procedure, just with a longer stem to pull out. One important difference: never leave a hose attached to a frost-free faucet in freezing weather. A connected hose traps water in the stem, the faucet cannot drain, and the trapped water can split the pipe inside your wall — a far more expensive repair than a washer.

If a new washer does not stop the drip on a frost-free unit, the valve seat deep inside may be damaged, or the long stem may be bent. At that point, replacing the whole sillcock is usually the practical answer.

Reassemble and Test

1. Close the outdoor faucet fully.
2. Slowly reopen the interior shutoff valve (or the main) and listen for rushing water that would signal a problem.
3. Go outside and check the faucet: no drip from the spout, no weep around the handle.
4. Open the faucet fully, then close it, and check again. Attach a hose and run water to confirm everything works under pressure.
5. If the handle weeps slightly, tighten the packing nut another eighth of a turn.

Preventing Future Leaks

• Disconnect hoses before winter and drain the faucet. This is the single most important habit — see our guide to winterizing outdoor faucets.
• Do not overtighten the handle when shutting the faucet off. Cranking it crushes the washer and shortens its life. Firm is enough.
• Fix small drips promptly. A washer that has just started to wear is a five-minute fix; one that has been dripping for months can erode the valve seat.
• Insulate exposed pipes in unheated areas to reduce freeze stress on the faucet and its supply line.

When to Call a Plumber

DIY washer replacement covers the majority of outdoor faucet leaks, but call a professional if:

• Water is leaking from inside the wall or the basement ceiling below the faucet — this suggests a split pipe.
• The faucet body itself is cracked or the threads are stripped.
• The shutoff valve will not close, or the stem breaks off during disassembly.
• You have a frost-free faucet whose seat is damaged deep inside the wall.
• You are not comfortable shutting off the water or working with plumbing — there is no shame in that, and a plumber can do this repair quickly.

Frequently Asked Questions

Why does my outdoor faucet leak even when it is turned off?

The rubber bibb washer that seals the valve has worn out, hardened, or has grit trapped under it. Replacing the washer, as described above, fixes this in most cases.

Can I repair the faucet without shutting off the water?

No — do not attempt it. Removing the stem with the water on will cause a high-pressure spray and can damage the faucet. Always close the interior shutoff or the main first.

How do I know if I have a frost-free faucet?

Frost-free sillcocks have a noticeably long stem (the handle sits several inches out from the wall on a long tube) and are usually angled slightly downward. Standard hose bibs have a short body right at the wall surface.

My faucet leaks from the vacuum breaker cap on top. Is that the same fix?

Not quite — that small cap is an anti-siphon vacuum breaker with its own rubber seal. Replacement vacuum breaker caps are inexpensive and thread on by hand; check yours if water sprays from the top when the faucet runs.

How long should a hose bib washer last?

Several years under normal use, but overtightening the handle, leaving hoses attached in winter, and hard water all shorten its life. Inspect it whenever you notice a drip starting.

Is a dripping outdoor faucet an emergency?

A slow drip is not an emergency, but do not ignore it. It wastes water, can freeze into an ice hazard in winter, and constant moisture can damage siding and trim.

Know Your Faucet Type Before You Buy Parts

Outdoor faucets are not all the same, and buying the right washer the first time saves a return trip to the hardware store:

• Standard compression hose bib: the classic multi-turn handle. Uses a flat bibb washer at the end of the stem. Most common on older homes.
• Quarter-turn ball-valve hose bib: the handle turns only 90 degrees. These use O-rings and a ball mechanism rather than a compression washer — if one leaks, look for a rebuild kit specific to the brand, or replace the whole unit.
• Frost-free sillcock: long stem reaching into the heated wall cavity. Uses a bibb washer like a compression bib, but located at the inner end of the long stem. Measure the stem length (8, 10, or 12 inches are common) if you need parts.
• Anti-siphon models: have a vacuum breaker cap on top to prevent backflow contamination. Required by code in many areas for new installations.

If the brand name is stamped on the faucet body, bring it with you — many manufacturers sell exact-fit repair kits with the washer, packing, and screws matched to your model.

Replaced the Washer and It Still Drips? Troubleshooting

• Wrong washer size or thickness: a washer that is slightly too small will not seal; too thick and the stem may not seat properly. Compare old and new side by side.
• Debris under the washer: a grain of sand or mineral flake between the washer and seat defeats the seal. Remove the stem, flush the body with water, and reinstall.
• Damaged valve seat: run your fingertip over the seat inside the body. If it feels pitted or has a groove worn into it, the new washer cannot seal. A seat-dressing tool (under $15) grinds the seat smooth again in a few turns.
• Cracked stem or loose washer screw: inspect the stem for hairline cracks and make sure the washer screw is snug — a loose screw lets the washer shift off-center.
• High water pressure: if every faucet in the house drips or toilets run constantly, your home’s water pressure may be excessive (above ~80 PSI). A plumber can test it and install a pressure-reducing valve if needed — this protects every fixture in the house.
