Most people associate frozen pipes with snowy climates like Colorado or the Midwest. But every winter, plumbers in the Las Vegas Valley respond to dozens of calls for burst pipes caused by overnight freezing temps. The desert may be warm during the day, but the drastic drop at night can lead to severe plumbing issues.

Here’s why it happens— and what you can do to protect your home.

Why Pipes Freeze in the Desert

Las Vegas has one of the largest temperature swings in the United States.
Winter days may sit around 55–60°F, but nights often dip into the low 30s — sometimes even the 20s.

These sudden shifts cause exposed plumbing to freeze faster than one might expect.

Pipes most at risk include:

• Outdoor plumbing lines
• Uninsulated garage pipes
• Water heater connections
• Irrigation lines
• Bathroom/kitchen pipes on exterior walls

All it takes is a few hours below 32°F for water in pipes to freeze and expand.

Warning Signs Your Pipes May Be Freezing

Before a full burst occurs, watch for signs such as:

• Little or no water flow in faucets
• Gurgling or odd sounds from pipes
• Frost on exposed plumbing
• Unusual odors from drains
• Sudden drops in water pressure

If you notice these signs, act quickly to prevent damage.

Why Hard Water Makes the Issue Worse

Las Vegas is known for extremely hard water. Mineral buildup inside pipes makes them:

• Narrower
• More brittle
• More prone to bursting when frozen

This is why even newer homes are not immune to freeze damage.

How to Prevent Frozen Pipes

Protecting your plumbing doesn’t require much effort — just a few proactive steps:

1. Insulate At-Risk Pipes

Pipe insulation is inexpensive and provides major protection.

2. Let Faucets Drip on Cold Nights

Running water is less likely to freeze.

3. Open Cabinets With Plumbing

Allows warm air to circulate around pipes.

4. Keep Thermostat at 55°F or Higher

Especially when away from home.

5. Cover Outdoor Faucets

One of the simplest and most important steps.

What to Do If Your Pipes Freeze

If you suspect a freeze:

• Turn off your main water supply immediately
• Open indoor faucets to relieve pressure
• Use gentle heat (space heater, hair dryer) on exposed pipes — never open flame
• Call a licensed plumber if you’re unsure

Delaying repairs can lead to catastrophic flooding.
