How to Fix an Outdoor Faucet Leaking From the Handle

A leak around the handle (not the spout) is a packing or O-ring problem — a $1 fix once you know which part to replace. Here is the step-by-step.

An outdoor faucet that leaks from around the handle — not from the spout — is a specific problem with a specific fix. The seal between the valve stem and the packing nut has worn out, and water is escaping past it whenever the faucet is on. This is different from a worn washer (which causes spout drips when off). The fix takes 15 minutes and costs about a dollar, but only if you know which part to replace.

This guide walks through how to fix an outdoor faucet leaking from the handle, plus how to tell whether you have the right diagnosis.

What You’ll Need

  • Adjustable wrench
  • Phillips screwdriver
  • Replacement packing washer or O-ring (bring the old one to match — $1)
  • Plumber’s tape (PTFE)
  • A bucket and a rag
  • Optional: penetrating oil if parts are corroded

Step 1: Confirm It’s a Handle Leak

Outdoor faucets leak from three different spots, and each needs a different fix.

  • Drips from the spout when the faucet is off → worn washer at the bottom of the stem. See how to fix a leaky outdoor faucet.
  • Water seeping around the handle when the faucet is on → packing/O-ring problem (this article).
  • Water from the wall around the faucet → frost-cracked pipe inside the wall. Bigger job.

To confirm:

  1. Turn the faucet on.
  2. Watch the handle area carefully. If water beads or drips from where the stem meets the packing nut, you’ve got a handle leak.
  3. Turn the faucet off and watch the spout. If it still drips from the spout, you have a second problem to fix too.

Step 2: Shut Off Water to the Faucet

Most outdoor faucets have a dedicated shut-off valve inside the house — basement, crawl space, or utility room near the wall where the faucet exits. Look for a small valve on copper or PEX pipe.

  1. Close it (clockwise).
  2. Open the outdoor faucet to drain remaining water.
  3. Leave the handle open during the repair.

If no dedicated shut-off, use the main water shut-off for the house.

Step 3: Try Tightening First

Before disassembling anything, try the simplest fix.

  1. Use a wrench on the packing nut (the large hex nut behind the handle).
  2. Turn clockwise about a quarter turn — just to snug it.
  3. Turn the water back on and test.

If the leak stops, the packing washer just needed compression. You’re done — 30 seconds of work.

If it still leaks, or the packing nut spun freely without resistance, the seal is shot. Continue to Step 4.

Step 4: Remove the Handle and Stem

  1. Most outdoor faucet handles are held on by a single screw at the top center. Remove it with a screwdriver.
  2. Pull the handle straight off the stem.
  3. Use a wrench to fully unscrew the packing nut (counterclockwise).
  4. The stem assembly will come out. Set it on a clean rag.

If the stem is stuck:

  • Spray penetrating oil around the packing nut and at the base of the stem.
  • Wait 10 minutes.
  • Try again.

Step 5: Replace the Packing Material

You’ll see one of two designs at the top of the stem, just below where the handle attached:

Older design: graphite packing string

Looks like dark, waxy string wrapped around the stem. Old; common on faucets from the 1990s and earlier.

  1. Unwind and discard the old packing string.
  2. Take the stem to the hardware store and buy graphite-impregnated packing string (sold by the foot).
  3. Wrap 3–5 turns around the stem at the same location, snugly but not piled up.
  4. Reassemble.

Newer design: rubber O-ring

A small rubber ring around the stem. Common on faucets from the 2000s+.

  1. Slide the old O-ring off the stem.
  2. Take it to the store and match exactly (diameter and thickness both matter).
  3. Slide the new O-ring on.
  4. Apply a thin smear of plumber’s grease to the new O-ring — this dramatically extends its life.
  5. Reassemble.

Step 6: Reassemble

  1. Slide the stem back into the faucet body.
  2. Hand-tighten the packing nut, then snug it with a wrench — quarter turn past hand-tight.
  3. Don’t crank — overtightening makes the handle hard to turn.
  4. Reattach the handle and tighten the handle screw.

Step 7: Test

  1. Slowly open the shut-off valve.
  2. Turn the outdoor faucet on full.
  3. Watch the handle area carefully for 30 seconds. Should be dry.
  4. Turn the faucet off and on a few times. Confirm the handle moves smoothly and seals each time.

If still leaking after a new O-ring or packing:

  • Check that you got the right size — slightly wrong sizes look identical but don’t seal
  • The stem itself may be scored or pitted (in which case, replace the entire stem assembly — about $5–10)
  • For very old faucets, replacement of the whole faucet may be cheaper than continued repair

Common Mistakes to Avoid

Replacing the wrong part. A handle leak is NOT a washer problem. The washer is at the bottom of the stem and only affects spout drips. Replacing it won’t help.

Forgetting plumber’s grease on the new O-ring. A dry O-ring fails in months. A greased one lasts years.

Overtightening the packing nut. Makes the handle stiff and accelerates O-ring wear. Snug + quarter turn is right.

Not bringing the old part to the store. O-rings and packing washers come in dozens of sizes. Guessing rarely works.

Reusing old packing string. It’s already compressed and worn. Always replace.

Frequently Asked Questions

Why does my outdoor faucet only leak at the handle in spring? The faucet probably leaked all along, but you didn’t notice during winter when you weren’t using it. Spring’s first use reveals it. Frost damage causes spout/wall leaks, not handle leaks.

Should I replace the whole stem? If just the O-ring is worn, no — that’s a $1 fix. If the stem is corroded, pitted, or visibly damaged, yes — replacement stems are $5–10 and screw in like-for-like.

Can a handle leak cause foundation damage? Less than a spout drip, since the water comes out the handle and falls away from the wall. But it’s still wasteful and worth fixing.

My handle is hard to turn after the repair. Packing nut is too tight. Loosen it a quarter turn at a time until the handle moves smoothly without leaking.

Is this the same as a kitchen faucet repair? The concept is similar, but the parts are different — kitchen faucets use cartridges or ceramic discs; outdoor faucets use simpler stem-and-washer designs. The skills transfer but the parts don’t.

A Sealed, Dry Handle

A handle leak on an outdoor faucet is genuinely one of the easiest plumbing fixes you’ll ever do. Identify the right design (packing string or O-ring), buy the matching part, swap it in 15 minutes. Add a tiny smear of plumber’s grease and the seal will outlast the rest of the faucet.
