How to Winterize Your Pipes in Kansas City

Kansas City winters are unpredictable. One week it's 50 degrees, the next it's single digits with a wind chill that makes it feel like the Arctic. That temperature whiplash is exactly what causes frozen pipes — and a frozen pipe that bursts can dump hundreds of gallons of water into your home before you even realize what happened.

After 35+ years of fixing burst pipes in Kansas City homes, we've seen what happens when homeowners skip winterizing. The good news is it's not complicated, doesn't cost much, and takes less than a few hours to do it right.

Why Kansas City Homes Are Especially Vulnerable

A lot of KC homes were built in the 60s, 70s, and 80s when pipe insulation wasn't a priority. Pipes in exterior walls, crawl spaces, garages, and unheated basements are the most at risk. When temperatures drop below 20°F — which happens several times every winter in KC — those pipes can freeze in just a few hours.

Step 1 — Know Where Your Main Shutoff Is

Before you do anything else, make sure everyone in your household knows where the main water shutoff valve is. If a pipe does burst, turning off the water in the first 60 seconds is the difference between a minor repair and a major disaster. In most KC homes it's in the basement near the front of the house or where the water line enters the foundation.

Step 2 — Insulate Exposed Pipes

Any pipe that runs through an unheated space needs insulation. This includes pipes in crawl spaces, garages, unfinished basements, and exterior walls. Foam pipe insulation sleeves are available at any hardware store for under $1 per foot and take minutes to install — just split them along the seam and snap them onto the pipe.

• Focus on pipes within 6 inches of an exterior wall
• Don't forget pipes under kitchen and bathroom sinks on exterior walls
• Check your garage if it has a utility sink or water line running through it
• Crawl spaces are a major vulnerability in older KC homes — check them every fall

Step 3 — Disconnect and Drain Outdoor Hoses

This is the most commonly skipped step and one of the most common causes of burst pipes we see. If you leave a garden hose connected to an outdoor spigot, water stays trapped in the line and can freeze and back up into the pipe inside your wall. Disconnect every hose before the first hard freeze, and if your home has standard spigots (not frost-free), shut off the interior valve and open the spigot to drain the line.

Step 4 — Keep Your Heat On (Even When You're Away)

If you're leaving town for the holidays, do not turn your heat off or set it below 55°F. The money you save on your gas bill is nothing compared to the cost of a burst pipe. Set it to at least 55-60°F and ask a neighbor to check on your house if you'll be gone more than a day or two.

Step 5 — Open Cabinet Doors on Cold Nights

On nights when temperatures are forecast to drop below 15°F, open the cabinet doors under sinks on exterior walls — especially in kitchens. This lets warm air from your home circulate around those pipes. It sounds too simple to matter, but it works.

Step 6 — Let Faucets Drip During Extreme Cold

When temperatures are forecast below 10°F, let faucets fed by vulnerable pipes drip slightly overnight. Moving water is much harder to freeze than standing water. It wastes a small amount of water but can prevent thousands in damage.

If You're Going on Vacation — Shut Off the Water Entirely

The safest thing you can do when leaving for an extended trip in winter is shut off the main water supply and drain the lines by opening faucets throughout the house. This eliminates the possibility of a burst pipe flooding your home while you're away. Ask your plumber to walk you through this the first time.
