How to Protect Outdoor Faucets from Freezing in Utah Winters

Winter in Utah isn’t just about bundling up, it’s also a season of hidden risks for your home’s plumbing system. One of the most overlooked areas? Your outdoor faucets (sometimes called hose bibs or spigots). Left un-prepared, they can become the source of burst pipes, hidden leaks, and major repair bills when the mercury drops.

If you’re a homeowner in Murray, Salt Lake County or elsewhere in the Beehive State, now is the time to act. Below, you’ll find why this risk is elevated in Utah, how to protect your outdoor plumbing step by step and how our winter exterior-plumbing check service can help.

Why Outdoor Faucets Are a Winter Plumbing Weak Point in Utah

In Utah, outdoor faucets are one of the most common winter plumbing weak points. Many homes have water supply lines that run through exterior walls, garages, or crawl spaces—areas exposed to extreme cold. When an outdoor faucet is left connected and un-drained, the water trapped between the house shut-off and the spigot can freeze, expand, and rupture the line. The first freeze of the season often catches homeowners off guard; a rapid drop to sub-freezing temperatures combined with residual water in the line creates a high risk for burst pipes.

If a hose remains attached and water is still inside the faucet, freezing pressure doesn’t just damage the outdoor fixture, it can push backward into your home’s plumbing system, leading to leaks or ruptures inside walls. Utah’s water conditions make the situation worse: colder incoming water, heavier winter usage, and high mineral content increase wear on pipes. Scale buildup narrows pipe interiors, leaving less room for expansion during freezing.

The result is that a seemingly minor exterior fixture, a simple outdoor spigot can become the starting point for major interior flooding, wall damage, and costly insurance claims, all at the time of year you least want plumbing problems.

Step-by-Step: How to Winterize Your Outdoor Faucet in Utah

Follow these steps to give your home the protection it needs as winter sets in:

Disconnect garden hoses and all external attachments
Remove any hoses, timers, splitters, or other attachments from your outdoor faucet. If water remains in the hose, it can freeze, expand, and pressurise back into your faucet and house line.
Shut off the interior supply valve for the exterior spigot
Many homes have a shut-off valve inside, near the point where the exterior faucet supply line enters the basement or crawl space. Close that valve to isolate the outdoor line. If you don’t have one, consider installing one now.
Open the outdoor faucet to drain the line
After shutting off the supply, open the spigot so residual water can drain out. Leave the faucet in the open position so any remaining water has space to expand rather than bursting the line.
Install a foam or insulated cover over the faucet
Cover the spigot with an insulated foam sleeve or rigid cover to reduce cold-air exposure. Even though the water line is drained, adding this small layer further reduces risk.
Inspect the spigot and line for any minor leaks or drips
Before winter sets in, check the outdoor faucet for signs of leakage, rust, wear or corrosion. A faucet that drips even slightly is at higher risk of freezing damage. Repair or replace if necessary.
Label the shut-off and spigot supply line for future reference
It’s smart to mark the shut-off valve, note the line path and ensure anybody who services your home knows the exterior plumbing route. A quick reference helps during emergencies.
Call in a professional exterior-plumbing winterization check
If your home has multiple outdoor spigots, older plumbing, or you’re unsure where the supply lines run—schedule a service call with us. We’ll inspect all exterior lines, verify insulation and shut-offs, and advise on weak points before the first hard freeze.
