The last thing you need during the busy holiday season is a plumbing disaster. Knowing how to winterize your home’s plumbing before cold weather arrives can help you avoid emergencies, costly repairs, and unnecessary stress. Unfortunately, if you don’t prepare your home’s plumbing system for the winter season, you risk dealing with burst pipes, leaks, or flooding problems no homeowner wants during a time when budgets are stretched.
There’s never a “good time” for a plumbing emergency, but winter tends to bring them when you’re least prepared. While you’re stocking the fridge for holiday gatherings or making up the guest room for visiting family, don’t forget that cold temperatures can quickly lead to pipes freezing and significant water damage. A little plumbing winterization now can save you from big headaches later.
Winterize the Plumbing System: Prevent Frozen Pipes, Leaks, and Flooding
The best way to avoid costly repairs during the winter season is to take action before the first deep freeze. Preparing your home’s plumbing system now will help prevent pipes from freezing, leaks, and the potential for water damage from burst pipes. These proactive steps will keep your plumbing pipes in top condition and ensure your home remains safe, even during cold temperatures and winter weather.
Here are our top tips to winterize pipes and prepare your plumbing pipes for freezing weather:
1. Prevent frozen pipes
When temperatures drop below freezing, water inside your pipes can solidify, causing them to expand and potentially burst. If this happens while you’re away, you could return to severe flooding and costly structural damage. Insulating exposed water lines in attics, crawl spaces, and unheated areas, such as garages, can prevent cold air from reaching them and reduce the risk of water pipes freezing.
To further protect your home’s plumbing system, let faucets drip slightly during extreme cold to relieve pressure inside pipes. Keep cabinet doors open under sinks on exterior walls to allow warm air to circulate—also, seal gaps or cracks around pipe entry points to block drafts. If you’ll be away for an extended period, shut off your main water valve and drain your plumbing pipes to remove any remaining water.
You’ll find more cold-weather strategies in the “Preparing Indoor Plumbing for Winter” section, ensuring your home stays protected throughout the entire season.
2. If you leak, fix it now
Small leaks can quickly escalate in winter. Cold weather increases stress on plumbing pipes, making existing leaks more likely to worsen. Inspect all faucets, showers, bathtubs, and toilets for drips. If you find one, call a plumber immediately. Prompt plumbing repair now is far less expensive than emergency service later.
3. Take care of your water heater
Your water heater works harder in winter. If you have hard water, sediment can build up inside the tank, leading to rust and reduced efficiency. Drain and flush the tank to remove buildup, and check the temperature setting to ensure optimal performance in cold weather. If your water heater shows signs of rust or aging, consider replacing it before the winter weather strains it further.
4. Stash away the garden hose
Disconnect and store your garden hose for the season. Leaving it attached allows remaining water inside to freeze, expand, and push ice back into the faucet and connected plumbing pipes, potentially causing damage. If your home has a separate shut-off for outdoor faucets, turn it off and drain the water from those faucets. Consider upgrading to frost-free hose bibs and investing in hose bib covers for more protection.
5. Take care of outdoor shut-off valves
Close interior shut-off valves that lead to exterior faucets and drain any remaining water from the lines. If water freezes in these pipes, you could face extensive and costly repairs in the spring. Use insulated faucet covers for added protection.
6. Prep your sump pump
Clean your sump pump and test it before winter storms hit. Ensure the discharge line is clear to allow melted snow and ice to drain away, thereby preventing basement flooding.
7. Additional fall plumbing tips
● Clean gutters to prevent ice dams and water backups.
● Seal exterior drafts around plumbing access points.
● Run appliances like dishwashers and washing machines during off-peak hours to reduce strain on your water heater.
By taking these steps early, you’ll safeguard your home’s plumbing system against freezing weather and avoid mid-winter surprises.
Preparing Indoor Plumbing for Winter
While outdoor systems face the most exposure, indoor plumbing in unheated spaces, such as garages, basements, and areas along exterior walls, face the same risks from cold air and low temperatures. Taking a few preventive measures indoors can be the difference between a worry-free season and an expensive plumbing repair bill.
Here’s how to safeguard those vulnerable spots:
● Insulate pipes in unheated rooms to reduce heat loss.
● Use pipe sleeves or UL-listed heat tape and cables in high-risk areas for added protection.
● Seal gaps and cracks around windows, doors, and pipe entry points using caulk or spray foam to fill the voids to keep cold air out.
● Keep cabinet doors open under sinks on exterior walls to allow warm air to circulate.
● Let faucets drip slightly during extreme cold weather to prevent ice buildup and pressure inside pipes.
● If you’ll be away, turn off the main water valve and drain all faucets to remove remaining water.
These steps work hand-in-hand with your outdoor plumbing winterization efforts to protect against pipes freezing, burst pipes, and costly water damage.
