Utah Winter Water Damage Prevention:
6 Things to Do Before the Cold Hits

Fix Existing Leaks Before They Become Winter Problems

A small drip under the kitchen sink or a slow seep around a pipe fitting might not seem urgent in summer. In winter, it can become a much bigger problem. Small leaks invite mold in the cold, and any water left near uninsulated areas can freeze and expand, turning a drip into a burst.

Before the temperature drops below freezing, do a walkthrough of your home: check under sinks, around the water heater, under the dishwasher, and anywhere else you've noticed moisture or heard dripping. Fix anything that needs fixing now, while it's easy.

Insulate Your Pipes - Especially in Utah's Cold Spots

Frozen pipes are the number one cause of water damage claims in Utah during winter. Water expands when it freezes - and it doesn't care that there's a copper or PVC pipe in the way. Burst pipes can release hundreds of gallons of water into your home in a matter of hours.

Foam pipe insulation is inexpensive and easy to install. Focus on:

• Pipes in unheated spaces: garage, crawl space, attic
• Pipes along exterior walls
• Any pipe in an area that gets cold drafts
• The pipe leading to and from your water heater if it's in a cold space

If you've had a pipe freeze before in a specific location, that spot needs extra attention - add electric heat tape along with the foam insulation.

Winterize Your Swamp Cooler

If you're from outside Utah, you might be wondering what a swamp cooler has to do with water damage. If you're from Utah, you already know - evaporative coolers are everywhere here, and forgetting to winterize yours is one of the most common (and preventable) causes of indoor water damage every fall.

A swamp cooler that isn't properly winterized can freeze and crack, sending water through your roof and into your ceiling. The fix is straightforward:

• Shut off the water supply line to the cooler
• Drain the water pan completely
• Disconnect and drain the water line
• Cover the unit with a cooler cover (not a plastic bag - condensation)
• Seal the duct opening inside to prevent cold air drafts

Do this before the first hard freeze. In the Salt Lake Valley, that can happen as early as mid-October.

Protect Your Hose Bibs (Outdoor Faucets)

Outdoor hose bibs are one of the most commonly forgotten freeze points. The pipe behind the bib runs through your exterior wall - if water is left in it when the temperature drops, it can freeze, crack the pipe, and when it thaws, you get water flowing inside your wall where you can't see it.

The fix is simple:

• Remove and store garden hoses - a hose left connected traps water and pressure
• Locate the shutoff valve for each hose bib (usually in the basement or crawl space) and turn it off
• Open the outdoor faucet to let any remaining water drain out
• Consider a foam hose bib cover for extra protection (they're $3 at any hardware store)

If your home has frost-free sillcocks (the newer style), they're more freeze-resistant - but only if there's no hose connected. A connected hose defeats the frost-free design.

Winterize Your Sprinkler System

If your home has an in-ground sprinkler system, winterizing it is non-negotiable in Utah. Water left in underground lines will freeze, expand, and crack the pipes and fittings - often at multiple points throughout the system. Repairs in spring can run into the thousands of dollars.

The proper method depends on your system. Gravity-drain systems can drain themselves if sloped correctly. Manual drain systems require opening drain valves. Most Utah sprinkler systems require blowout with compressed air - which forces water out of all the lines before freeze.

Blowout is typically a job for a professional with the right compressor (incorrectly sized air pressure can damage the system). Most sprinkler companies offer fall blowouts for $50–$100 - well worth it against a spring repair bill.

After blowout, turn off the controller or set it to "rain" mode so it doesn't try to run empty lines during a warm winter day.

Locate Your Water Main Shutoff

This one is less about prevention and more about response - but it can mean the difference between a small water damage claim and a catastrophic one. If a pipe bursts while you're home, how fast can you stop the water?

Find your main water shutoff valve right now, before you need it. In Utah homes it's typically:

• In the basement near the front of the house
• In a utility room or mechanical room
• In the garage (less common)
• In a crawl space access panel

Once you locate it, make sure it turns. Valves that haven't been operated in years can seize. Turn it on and off once to confirm it works. Consider labeling it clearly so anyone in your household can find it in an emergency.

Every minute matters when a pipe bursts. Knowing where your shutoff is before an emergency can save thousands of dollars in damage.
