How to Prevent Frozen Pipes in Your Utah Home: A Winter Checklist for Homeowners

By Dan VanSweden, REALTOR® | VanSweden Real Estate Group, KW Westfield (Excellence) | Helping Utah buyers and sellers since 2017

To prevent frozen pipes in a Utah home, disconnect garden hoses, shut off and drain your sprinkler lines once secondary water stops, insulate pipes in garages and crawl spaces, and keep the heat steady day and night. Most freeze damage along the Wasatch Front starts at outdoor faucets and unheated spaces, so start there before the first hard cold snap.

I'm a Spanish Fork–based agent serving Utah, Salt Lake, Davis, Weber and Wasatch counties, and frozen-pipe damage is one of those winter problems that's much easier to prevent than to fix. Here's a simple checklist to protect your place.

When should Utah homeowners get ready for freezing weather?

Late October is the right time in most of the Wasatch Front, because secondary (pressurized irrigation) water is shut off for the season and overnight lows start dipping below freezing. Don't wait for the first snow on the valley floor.

In Spanish Fork, for example, the city says its pressurized irrigation system typically runs from about mid-April to mid-October, with exact dates varying each year. The city also notes that homeowners are responsible for the irrigation lines past the first fitting after the city's meter. Many other Utah County, Salt Lake County and Davis County cities follow a similar fall shutdown, so check your own city or irrigation company's schedule.

How do you winterize outdoor faucets and sprinklers?

Unhook every hose, turn off your sprinkler system at its valve, and drain or blow out the lines. Water left trapped in a hose or sprinkler pipe is a common cause of split pipes.

• Disconnect hoses. A FOX 13 report from October 2026 notes that water left in an attached hose can freeze and split a pipe inside the wall, and that leak might not show up until spring.
• Close the sprinkler valve. Spanish Fork's past shutoff reminder tells residents to open the green PI box near the sidewalk and turn the valve perpendicular to the pipe so spring start-up doesn't flood the yard.
• Drain or blow out the lines. Follow your sprinkler manufacturer's directions, or hire a local sprinkler company to blow out the system with compressed air.
• Shut off and drain indoor valves to hose bibs if your home has them, and consider foam faucet covers for extra protection.

Which pipes inside a Utah home are most likely to freeze?

Pipes in unheated or exterior spaces freeze first: garages, crawl spaces, unfinished basements along outside walls, and kitchen or bathroom sinks on exterior walls. Insulating these is cheap and fast.

• Wrap exposed pipes in garages and crawl spaces with foam pipe insulation, a step FOX 13's report also recommends.
• Keep the garage door closed, especially if a water line or water heater is in the garage.
• Seal gaps where cold air reaches pipes, such as around dryer vents, hose bib penetrations and crawl space vents.
• Know where your main water shutoff is before you need it, and make sure everyone in the house can find it.

What should you do during a cold snap or when you travel?

Keep the house warm around the clock, open sink cabinets on exterior walls, and let a faucet drip during the coldest nights. If you're leaving town, don't turn the heat way down.

The American Red Cross tips summarized by CBS News include letting a trickle of water run when freezing temperatures are forecast, keeping the home warm day and night, and opening cabinets so warm air reaches the pipes. The same article recommends keeping the thermostat no lower than 55 degrees when you're away. For longer trips, ask a neighbor to check on the house.

What if a pipe freezes or bursts?

If a faucet only trickles, keep it open and warm the pipe gently. If a pipe bursts, shut off the main water valve right away and call a plumber.

• Use gentle heat such as a hair dryer, heating pad or warm towels. Never use an open flame like a torch.
• Keep applying heat until full water pressure returns, then check for leaks.
• Take photos of any damage for your insurance company before cleanup.

While you're thinking about the furnace running all winter, it's also a good time to test carbon monoxide alarms. The Utah Poison Control Center recommends an alarm on each level near sleeping areas, checking batteries twice a year, yearly service for gas appliances, and clearing snow from exhaust vents after storms. Clocks fall back on November 1, which makes a handy reminder.

Why this matters if you plan to sell

Water damage is one of the issues that shows up in buyers' inspections and can complicate a sale, so preventing it protects your home's value.

Frequently Asked Questions

Do I need to blow out my sprinklers in Utah, or is shutting off the valve enough?

Shutting off the valve stops new water from coming in, but water can still sit in the lines and freeze. Draining or blowing out the system, following your manufacturer's instructions or using a sprinkler company, is the safer choice for Utah winters.

Should I leave my faucets dripping all winter?

No. Dripping is mainly for the coldest nights, especially for sinks on exterior walls or pipes that have frozen before. On ordinary winter nights, steady heat and insulated pipes are usually enough.

Does homeowners insurance cover a burst pipe?

Coverage depends on your specific policy and the cause of the damage, so review your policy or call your insurance agent before winter. Either way, preventing a freeze is far easier than cleaning up after one.
