Top 5 Winter Plumbing Tips

When winter rolls around, you’re probably thinking of getting cozy under a blanket and drinking hot cocoa, but don’t forget about your plumbing. Frozen pipes are a real concern during colder months. Left unchecked, these can lead to leaks and costly repairs.

If you want to protect your plumbing this upcoming season, consider our top five winter plumbing tips.

Why Is Winterizing Your Plumbing Important?

Winterizing your plumbing is crucial for preventing frozen pipes. When temperatures drop, pipes — especially those exposed to the elements — can freeze, crack, and burst. This can lead to:

Severe water damage
Property loss
Mold growth

Not only is there a risk of pipes freezing, but you could also experience increased utility bills from inefficient plumbing and heating systems. Performing seasonal plumbing maintenance will ensure you avoid these risks and save money in the long run.

Tip #1 – Insulate Exposed Pipes, Outdoor Faucets, and Seal Air Leaks

To prevent frozen pipes, you’ll need to protect those exposed to the cold. Use pipe insulation on pipes in unheated or uninsulated areas like:

Attics
Basements
Crawl spaces
Exterior walls

Don’t forget to cover outdoor faucets with insulated covers to keep them safe. Finally, check where pipes enter and exit your home to ensure there aren’t any gaps. If there are, seal these with weatherproof caulking so cold air can’t get in.

Tip #2 – Keep a Slow Drip to Prevent Pipe Freezing and Circulate Warm Air

Water that's in motion is less likely to freeze. When temperatures drop below freezing, leaving the tap turned on just a little bit prevents ice from forming inside your pipes.

Typically, you’ll only need to worry about faucets on exterior walls or in unheated areas. To prevent wasting water, place a bucket under the slow drip and use the water you collect to water plants, fill up a pet’s water bowl, or clean your home.

Also, you’ll want to make sure these faucets receive enough warm air. Keep your thermostat set to at least 55° F day and night, and open up all cabinets and drawers underneath sinks so the hot air can circulate there.

Tip #3 – Shut Off And Drain Outdoor Plumbing

Chances are, you won’t need your outdoor hose during the winter. Here are a couple of outdoor plumbing tips for freezing weather to keep things safe:

Turn off indoor shut-off valves connected to outdoor faucets: This prevents water from standing in outdoor pipes, which can freeze and cause damage.
Open outdoor faucets to drain any remaining water: Allowing the water to drain from outdoor faucets will prevent freezing and ruptures in the pipe system.

Tip #4 – Prevent Pipe Bursts with Seasonal Plumbing Maintenance

The best way to prevent problems is to catch them before they start. You can do that with routine winter plumbing maintenance every fall, such as:

Checking for leaks before winter: Inspect pipes, faucets, and fixtures for any leaks and get them repaired before the first freeze.
Shut off and drain unused plumbing lines: If you have plumbing that’s not in regular use (like a basement shower or mother-in-law suite), drain these lines and turn them off for the season.

Tip #5 – Prepare Your Water Heater for Cold Weather

Your water heater works hard during the winter months, so make sure it's ready for the season.

Adjust the temperature for efficiency: Set your water heater temperature to 120° F to ensure it’s efficient and won’t waste energy.
Flush sediment buildup for better performance: Over time, sediment can build up inside your water heater, reducing its efficiency.
