Handle turns but water never slows down
The handle rotates through its normal range, but flow at the spout stays the same.
Start here: Start by checking whether the handle is stripped and no longer gripping the hose bib stem.
Direct answer: If a frozen hose bib will not shut off, the usual causes are a stem that is iced in place, a stripped handle that is no longer turning the stem, or freeze damage inside the hose bib. Start by finding out whether the handle is actually moving the valve and whether water is only at the spout or also showing up at the wall or inside the house.
Most likely: Most often, the handle feels like it turns but the valve does not close because the handle connection is stripped or the stem and packing area were damaged by freezing.
A hose bib that will not shut off in freezing weather needs quick, calm triage. Reality check: once ice has been inside the faucet, hidden damage is very possible even if the outside only looks frosty. Your first job is to separate a stuck exterior faucet from a cracked one and get control of the water before you think about parts.
Don’t start with: Do not force the handle with pliers or a wrench first. That is a common way to snap the stem or turn a manageable repair into a shut-water-now emergency.
The handle rotates through its normal range, but flow at the spout stays the same.
Start here: Start by checking whether the handle is stripped and no longer gripping the hose bib stem.
The faucet feels seized, often after a hard freeze, and you are tempted to force it.
Start here: Treat this as a frozen stem first and do not muscle it until you have checked for indoor shutoff access.
You may see dripping at the siding, around the mounting area, or inside the basement or crawlspace.
Start here: Assume freeze damage until proven otherwise and isolate the indoor supply right away.
The screw may be loose or missing, or the handle no longer bites onto the stem.
Start here: Inspect the hose bib handle and stem connection before touching anything else.
This is common when someone tries to shut off a stiff faucet after a freeze. The handle turns, but the stem underneath does not.
Quick check: Hold the handle and watch the center where it meets the stem. If the handle moves but the stem does not, the handle connection is stripped or loose.
Ice or corrosion can lock the stem in place so the faucet cannot close normally.
Quick check: If the handle is very stiff and the stem turns only a little or not at all, especially after a cold snap, the stem is likely frozen or seized.
A hose bib can freeze, crack internally, and stop sealing even if the handle still turns. Water may keep running because the valve no longer closes against the seat.
Quick check: If the handle feels connected and reaches its stop, but flow keeps going, internal freeze damage is likely.
On frost-free styles, the visible faucet may look fine while the split is farther back in the wall. Water can show up indoors or around the wall opening.
Quick check: Look in the basement, crawlspace, or utility area while someone opens and closes the faucet. Any dripping on the supply line or wall cavity points to a cracked assembly or pipe.
Before you troubleshoot, you need to know whether this is just a faucet that will not close or a freeze break that can soak the wall.
Next move: You have controlled the immediate water risk and can inspect the faucet without making the damage worse. If you cannot find a branch shutoff or the leak continues inside after shutting one valve, treat it as a larger plumbing leak and stop.
What to conclude: A spout-only problem usually points to the hose bib itself. Water at the wall or inside strongly suggests freeze damage beyond a simple handle issue.
A loose or stripped handle is one of the most common reasons an outdoor faucet seems like it will not shut off.
Next move: If the stem turns and the water shuts off, the handle was the problem. If the stem moves with the handle but the water keeps running, the problem is inside the hose bib, not just the handle.
What to conclude: A stripped handle points to a hose bib handle replacement. A moving stem with no shutoff points to internal stem or valve damage from freezing or wear.
These two look similar from the yard, but the feel of the handle tells you a lot and keeps you from buying the wrong part.
Next move: If gentle thawing restores normal shutoff and there is no leaking at the wall or stem, the faucet may have frozen at the exterior only. If the stem stays seized or turns fully without stopping flow, the hose bib itself is damaged enough to repair or replace.
Not every cold-weather hose bib failure means the whole faucet is done. Sometimes the handle side or top anti-siphon piece took the hit first.
Next move: You have narrowed it to a smaller repair instead of replacing parts blindly. If the faucet still will not shut off and no external repair point explains it, the internal valve is likely damaged and the hose bib may need replacement by a plumber.
Once you know which part failed, you can either make a small repair or stop before hidden freeze damage gets expensive.
A good result: You either solved the small failure or safely contained a freeze-damaged faucet until it can be replaced.
If not: If you still cannot tell whether the leak is in the faucet or inside the wall, do not reopen the branch unattended.
What to conclude: The common wrong move is replacing the handle when the real problem is a cracked frost-free stem or split pipe behind the wall.

Usually the handle is stripped, the stem is damaged, or the valve inside the hose bib no longer seals after freezing. Watch whether the stem turns with the handle. If it does and water still runs, the problem is deeper than the handle.
Sometimes a little exterior ice around the stem melts and the faucet works again, but do not count on that as a clean bill of health. Freeze damage often shows up after thawing, especially as stem leaks or hidden wall leaks.
Not always. A stripped hose bib handle or leaking stem packing can be a smaller repair. But if the stem turns and the faucet still will not close, or if water shows up at the wall or indoors, replacement is the more likely path.
Only very gently for confirmation if the handle is off and the stem is clearly intact. If it takes real force, stop. Twisting harder can snap the stem or crack an already weakened faucet body.
Shut off the indoor branch valve to that hose bib immediately, or the main water if you cannot isolate it. That points to freeze damage in a frost-free hose bib or the supply pipe behind it, which is not a keep-testing-outside situation.
