How to Keep Your Pipes From Freezing in Kingman
People forget Kingman gets cold. At this elevation, winter nights freeze, and unprotected pipes split. Here is how to get ahead of it before December.

The key point: Kingman sits above 3,300 feet, so despite the desert reputation, winter nights regularly drop below freezing, and any pipe outside the heated part of your home can freeze and split. The fix is prevention, done in the fall: insulate exposed lines, drain and shut off evaporative-cooler supply lines, and protect the vulnerable spots before the first hard freeze rather than after.
Frozen pipes are one of the most preventable emergencies there is, and also one of the most damaging when ignored, because a split line floods a house fast. Here is a practical, Kingman-specific plan to keep it from happening.
Why pipes freeze here at all
Daytime warmth in winter hides how far the temperature falls after dark. At this elevation, overnight lows below freezing are normal from late fall into early spring. Water expands as it freezes, and inside a closed pipe that expansion has nowhere to go, so the pipe splits, often without leaking until it thaws and water pours out. The pipes at risk are the ones outside the heated envelope: exposed runs in garages and crawlspaces, lines in well houses, and pipe under manufactured homes.
The evaporative cooler trap
The single most common freeze-and-split in Kingman is the evaporative cooler line. A cooler's water supply runs to the roof or an exterior wall, and if it is left charged with water through winter, that exposed line freezes and cracks. The fix is simple and seasonal: shut off the water to the cooler and drain the line in the fall, at the same time the cooler is covered. Doing it then avoids the classic spring surprise of turning the water back on and finding a line spraying into the roof space.
| Location | Risk | Prevention |
|---|---|---|
| Evaporative cooler line | Water left in an exposed run | Drain and shut off before winter |
| Garage and crawlspace pipe | Outside the heated space | Insulate, or reroute into warmth |
| Well house lines | Exposed and unheated | Insulate, add a heat source |
| Manufactured-home belly runs | Cold under the skirting | Insulate and skirt the underfloor |
| Hose bibs and outdoor faucets | Exposed to the air | Disconnect hoses, use covers |
Insulate what you cannot move
Exposed pipe that has to stay where it is should be insulated with foam pipe sleeves, which are cheap and easy to fit. Well houses benefit from insulation and, in the coldest spots, a safe heat source. Manufactured homes need the underfloor insulated and the skirting intact, since the belly runs sit in cold air otherwise. On the worst-placed lines, rerouting the pipe into heated space is a permanent fix worth considering, which overlaps with repiping decisions.
What to do during a cold snap
When a hard freeze is forecast, a few steps help. Let a faucet drip slightly on the coldest lines, since moving water resists freezing. Open cabinet doors under sinks on exterior walls to let warm air reach the pipes. Keep the heat on even in unused rooms. Disconnect garden hoses so water is not trapped at the hose bib. None of these replace insulation, but they help on the coldest nights.
If a pipe does freeze or burst
If you turn on a tap in winter and get nothing, a pipe may be frozen. Shut off the main water valve in case the pipe has already split, and call rather than trying to thaw it with an open flame. If a pipe has burst, shut the main immediately to stop the flooding, then call, since burst pipe repair is an emergency someone answers at any hour. Getting the water off is what limits the damage.
The prevention that pays for itself
An hour of fall prep, insulating a few runs and draining the cooler line, costs almost nothing next to a burst pipe and a soaked floor in January. If your home has old galvanized or thinned copper, a freeze is also more likely to be the last straw for a run that was already failing, which is where repiping the worst lines comes in. Get ahead of the cold, and winter stays uneventful.
Leaving for the winter?
Kingman has its share of seasonal residents, and an empty house in winter is exactly where a freeze does the most damage, because no one is there to catch it. If you are away for an extended cold stretch, do not just turn the heat down and leave. Shut off the main water valve and drain the lines so there is no water sitting in the pipes to freeze, keep the heat set to a safe minimum rather than off, and have someone check the house periodically. A burst pipe in an empty home can flood for days undiscovered, so a little winterizing before you go is worth the effort.
Frequently asked questions
Do pipes really freeze in Kingman?
Yes. Kingman sits above 3,300 feet, so winter nights regularly drop below freezing even when the days feel mild. Any pipe outside the heated part of the house, in a garage, crawlspace, well house, or under a manufactured home, is at risk. The desert reputation fools people, but freeze-and-split pipes are a real Kingman winter problem.
What is the most common frozen pipe in Kingman?
The evaporative cooler line. Its water supply runs to the roof or an exterior wall, and if left full of water over winter, that exposed line freezes and cracks. Draining and shutting off the cooler supply in the fall, when the cooler is covered, prevents the classic spring surprise of a line spraying into the roof.
How do I protect my pipes before winter?
Insulate exposed runs in garages, crawlspaces, and well houses with foam sleeves, drain and shut off the evaporative cooler line, and make sure manufactured-home underfloors are insulated and skirted. Disconnect garden hoses from outdoor faucets. Doing this in the fall, before the first hard freeze, is far cheaper than repairing a burst pipe later.
What should I do during a hard freeze?
Let a faucet drip slightly on the coldest lines, since moving water resists freezing. Open under-sink cabinets on exterior walls to let warm air in, keep the heat on throughout the house, and disconnect garden hoses. These help on the coldest nights but do not replace insulating the exposed pipes ahead of time.
A pipe froze. What do I do?
Shut off the main water valve in case the pipe has already split, then call a plumber rather than thawing it with an open flame, which is a fire risk and can burst the pipe. If a pipe has already burst, shut the main immediately to stop the flooding and call right away, since that is an emergency answered at any hour.
