Hose Bib Repair
A dripping hose bib wastes water. A split pipe behind the wall causes hidden damage.
Wes repairs dripping hose bibs and frozen pipe damage, and upgrades to frost-free models that hold up to Colorado winters.
Why hose bibs fail
Colorado freezes find every weak point.
A hose bib fails in two ways: the packing washer inside the stem wears out and the bib drips when shut off, or the pipe behind the bib inside the wall freezes and splits. The first is a quick repair. The second requires locating and cutting out the cracked section and installing a repair coupling.
The primary cause of pipe splits behind hose bibs is leaving a garden hose attached through the winter. Wes repairs the damage and installs a frost-free replacement. Get it fixed.
Here is the part that surprises people: a frost-free bib will still burst if a hose is left on it. The whole design depends on the water draining backward out of the stem when you close the valve. A hose attached to the end, especially one with a nozzle or a shutoff at the far end, seals the outlet and traps that column of water in the stem. It freezes in place, expands, and splits the tube in the exact spot the design was supposed to protect. So a homeowner who spent good money on frost-free bibs and never disconnects the hose is in the same position as the neighbor with plain ones. Pull the hoses in October and coil them up. That single habit prevents most of these calls.
The other thing worth knowing is that the split usually does not show up until spring. Water freezes, the tube cracks, and then it sits there sealed by ice all winter behind the wall. You turn the valve on in April to fill a bucket and the crack lets go inside the wall cavity with the valve wide open. That is why these failures so often mean drywall, insulation, and sometimes a finished basement ceiling on top of the plumbing repair.

Dripping hose bibs
A slow drip is not minor.
A hose bib that drips when shut off has a worn packing washer inside the stem. Shut off the interior supply valve, remove the stem, replace the washer, reinstall. The drip stops. If the bib has been dripping for a long time, the brass seat inside the body may be scored, requiring a seat grinder or full replacement.
Wes checks the interior shutoff valve condition while he is at the bib. A shutoff valve that has not moved in years may not fully close when you actually need it to.
Hard water is what wears these out early on the Front Range. The mineral content in most of the water around Denver and the foothills leaves scale on the seat and the stem threads, and that scale acts like sandpaper every time the valve is opened and closed. A washer that might have lasted a decade somewhere else gets chewed up in a few seasons here. It also means a bib that has been dripping a while has almost certainly scored the brass seat, so a fresh washer alone will not seal it. That is the reason a repair sometimes turns into a replacement, and Wes will tell you which one you are looking at once he pulls the stem rather than guessing at it from the driveway.
Where the bib drips is diagnostic too. Water coming out the spout when the handle is closed means the washer or the seat. Water coming out around the handle when the valve is open means the packing nut is loose or the packing washer behind it is shot, which is often a quarter turn away from being fixed. Water showing up at the siding below the bib means the connection behind the wall is leaking, and that one is not a washer job.

Frost-free hose bib installation
The right fix for Colorado.
A frost-free hose bib has a 6 to 12-inch stem that pushes the shutoff washer inside the heated wall space. When closed, water drains back through holes in the stem, leaving no water to freeze. In a Colorado climate they are the correct specification. Wes installs frost-free bibs as standard when replacing any hose bib. See our plumbing work.
Two details make the difference between a frost-free that works and one that fails anyway. The first is pitch. The whole bib has to slope slightly downward toward the outside so gravity carries the water out of the stem when the valve closes. Installed dead level or tipped back toward the house, it holds water no matter how long the stem is, and it splits the first cold week. The second is stem length. A six inch stem is fine through a two by four wall with siding, but on a house with brick veneer, thick foam sheathing, or a stone facade, that same stem leaves the shutoff sitting inside an unheated cavity. Then you have a frost-free bib that freezes. Wes measures the wall assembly before he picks the part.
The anti-siphon vacuum breaker on top of the bib matters more than its size suggests. It is the little brass cap that keeps water from being pulled backward out of a hose into the house supply. Picture a hose lying in a puddle of fertilizer or sitting in a filled kiddie pool when the main pressure drops because a line broke down the street. Without a working vacuum breaker, that water can siphon back into your drinking water. Those caps stick, corrode, and start weeping in Front Range water, and most people assume the drip is coming from the valve. They are inexpensive to replace and Wes checks them as part of any bib repair.
If the failure reached into the wall, frozen pipe repair covers the thaw and rebuild, and burst pipe repair covers the water damage side. For irrigation valves, yard hydrants, and buried lines, see outdoor plumbing repair. Call us and describe what you are seeing.
Repair the damage, prevent the next freeze
Hose bib repair done right.
Repairing a split pipe and putting the original standard bib back is a half-measure. Wes repairs the pipe and installs a frost-free replacement. One visit, right fix, protected going forward.
And when the repair means opening drywall, siding, or a basement ceiling to reach the split, that work is part of the job. Wes is a master plumber and a licensed general contractor, so the patch, the texture, and the paint-ready finish come from the same person who soldered the joint. No second trade to schedule, no waiting a month with a hole in the wall.

Questions about hose bib repair.
My hose bib drips when shut off. Is that serious?
It wastes water and it gets worse, and in Front Range hard water a long-running drip scores the brass seat so the repair grows. Where it drips tells you what failed: out the spout with the handle closed is the washer or seat, around the handle while it is open is the packing nut. The first is a quick fix.
How do I know if the pipe behind the hose bib split?
Turn it on in spring and watch inside. Weak flow or no flow outside plus water appearing on the interior wall, the ceiling below, or the basement means the tube split over winter and the ice that was sealing it just melted. Shut the interior valve immediately and call before more water gets into the framing.
What is the difference between standard and frost-free?
A frost-free has a long stem that puts the shutoff washer inside the heated wall, so closing it lets the water in the stem drain out through the spout. A standard bib shuts off right at the wall and leaves a full pipe sitting in the cold. In Colorado, frost-free is the right specification on every exterior wall.
Can I prevent hose bib pipes from freezing?
Disconnect every garden hose in October, drain them, and coil them somewhere out of the weather. If you have interior shutoff valves for the exterior bibs, close them and open the bib outside so the line between them drains. Insulated foam covers help on standard bibs but they do not replace disconnecting the hose.
I have frost-free bibs. Why did one still burst?
A hose was almost certainly left attached. The design only works if water can drain out the spout when you close the valve, and a hose, especially one with a nozzle or shutoff on the far end, seals that outlet and traps water in the stem. It freezes there and splits the tube in the very spot the long stem was meant to protect.
What is the little cap on top of the spigot?
That is the anti-siphon vacuum breaker. It stops water from being pulled backward out of a hose into your house supply if pressure drops, which matters when the hose end is sitting in a puddle or a pool. They stick and weep in our water, and people usually mistake that drip for a valve problem. Cheap to replace, and worth doing.
Can I replace a hose bib myself?
If it threads on and the interior shutoff works, some homeowners handle it. The trouble is getting the pitch right so it drains, picking a stem length that matches your wall thickness, and dealing with a soldered connection in a tight rim joist. Getting any of those wrong means a frost-free bib that freezes anyway next winter.
How long does a hose bib repair take?
A washer or packing repair is usually under an hour. A straight frost-free swap where the connection is accessible runs one to two hours. A split line inside the wall depends on access, and if drywall or siding has to come off, Wes handles the plumbing and the patch in the same visit rather than leaving you an open wall.
