Step-by-step fix
Step 1: Confirm this is the right repair
- Look at where the hose bib leaks. A drip from the spout after the faucet is shut off usually points to a worn stem washer. Water seeping around the handle usually points to worn packing.
- Check that the faucet body itself is not cracked, split, or badly corroded.
- Turn the handle open and closed. If it still turns and the stem can likely be removed, a packing and washer kit is a reasonable first repair.
- Close the water supply feeding the hose bib if you have a nearby shutoff. If not, shut off the main water supply before taking the faucet apart.
- Open the hose bib to relieve pressure and drain remaining water.
If it works: You have a leak pattern that matches worn packing or a worn washer, and the water is safely off.
If it doesn’t: If the leak is coming from a crack in the faucet body or from the pipe connection behind the wall, this kit is not the right fix.
Stop if:- The faucet body is cracked, split, or loose in the wall.
- The pipe behind the hose bib moves, leaks, or shows hidden damage when you touch the faucet.
- You cannot shut off water to the faucet safely.
Step 2: Remove the handle and stem parts
- Take off any hose attached to the spout.
- Remove the screw holding the handle, then pull the handle straight off. If it sticks, wiggle it gently instead of forcing it sideways.
- Use the adjustable wrench to loosen the packing nut behind the handle.
- Unscrew and remove the stem assembly from the faucet body, keeping the parts in order on a rag so you can reassemble them the same way.
If it works: The handle, packing nut, and stem assembly are out where you can inspect and rebuild them.
If it doesn’t: If the handle is seized, apply steady pressure and clean away corrosion first. If the stem will not back out without excessive force, the faucet may need full replacement instead.
Stop if:- The stem or faucet body starts deforming, cracking, or twisting under wrench pressure.
- The faucet is so corroded that parts are breaking apart during removal.
Step 3: Replace the old washer and packing
- Find the rubber washer at the end of the stem and remove the small screw holding it in place.
- Install the new washer from the kit in the same position and reinstall the screw snugly without overtightening it.
- Remove the old packing from around the stem under the packing nut. Use needle-nose pliers to pull out old packing material or rings.
- Install the new packing from the kit in the same location and orientation as the old part.
- Compare the new parts to the old ones before moving on so you do not mix sizes or install the wrong piece.
If it works: The worn sealing parts have been replaced with matching new parts from the kit.
If it doesn’t: If the new washer or packing does not match the old parts closely enough to seat properly, pause and get a better-matched kit for your faucet.
Stop if:- The stem screw is stripped or broken and cannot hold the new washer securely.
- The stem sealing surfaces are deeply pitted or damaged where the new parts need to seal.
Step 4: Clean and reassemble the hose bib
- Wipe mineral buildup and debris off the stem, packing nut, and the inside opening of the faucet body.
- Apply a light coat of plumber's grease to the stem threads and moving surfaces. Do not pack the faucet full of grease.
- Thread the stem assembly back into the faucet body by hand first to avoid cross-threading.
- Tighten the stem assembly until it seats, then snug the packing nut. Reinstall the handle and handle screw.
- Turn the handle closed gently. It should stop firmly without needing extra force.
If it works: The faucet is back together, the stem turns smoothly, and the parts are seated correctly.
If it doesn’t: If the stem feels cross-threaded, rough, or crooked, back it out and start the threads again by hand before tightening.
Stop if:- The stem will not thread in straight by hand.
- The packing nut or faucet body threads are damaged and will not tighten securely.
Step 5: Restore water and check for immediate leaks
- Turn the water supply back on slowly.
- With the hose bib closed, watch the spout for dripping for a minute or two.
- Open the faucet fully and check around the handle and packing nut for seepage.
- If water appears around the handle, tighten the packing nut a little at a time until the seepage stops. Do not overtighten it.
- Close the faucet again and watch the spout to see whether the shutoff drip has stopped.
If it works: The hose bib runs without leaking at the handle and shuts off without a steady drip from the spout.
If it doesn’t: If the handle still leaks after a small packing nut adjustment, or the spout still drips after the new washer is installed, the stem seat or the whole hose bib may be worn beyond this repair.
Stop if:- Water sprays or leaks heavily from the faucet body after reassembly.
- A small adjustment does not control the leak and the faucet condition is getting worse.
Step 6: Verify the repair holds in normal use
- Use the hose bib the way you normally would: open it fully, let water run for a few minutes, then shut it off.
- Check again around the handle, packing nut, and spout after the faucet has been under pressure.
- Come back after 10 to 15 minutes and confirm there is no renewed drip from the spout.
- If needed, make one final small packing nut adjustment for a faint handle seep, then retest.
If it works: The faucet operates normally, shuts off cleanly, and stays dry at the handle and spout during real use.
If it doesn’t: If the leak returns after normal use, the faucet likely has a worn valve seat, damaged stem, or body wear that calls for a larger repair or full replacement.
Stop if:- The faucet still will not shut off reliably after the new washer and packing are installed.
- You find water leaking inside the wall or structure behind the hose bib.

FAQ
What does the packing do in a hose bib?
The packing seals around the stem so water does not leak out around the handle when the faucet is open. When it wears out, you usually see seepage near the handle.
What does the washer do in a hose bib?
The stem washer helps seal the water flow when you turn the faucet off. When it wears down or hardens, the spout may keep dripping even though the handle is closed.
Can I just tighten the packing nut instead of replacing the kit?
Sometimes a small tightening of the packing nut will slow or stop a minor handle leak. If the leak comes back, or if the spout is dripping when shut off, replacing the packing and washer is the better fix.
Why is the hose bib still dripping after I replaced the washer?
A continued drip can mean the valve seat inside the faucet is worn or the stem is damaged. In that case, a packing and washer kit may not be enough, and the faucet may need a deeper repair or replacement.
Do I need to replace the whole hose bib if it is old?
Not always. If the body is solid and the stem comes apart cleanly, replacing the packing and washer kit is often worth trying first. If the faucet is cracked, heavily corroded, or will not come apart safely, full replacement makes more sense.
