How to Prepare Your Plumbing for Winter

As the days grow shorter and the temperatures start to drop, it’s time to start thinking about preparing your home for winter. While you may be focused on cozying up your living spaces and checking your heating system, don’t forget that your plumbing system also needs attention. Cold weather can wreak havoc on your pipes, leading to frozen pipes, leaks, and costly repairs. To avoid these issues, follow these essential steps to winterize your plumbing.

1. Insulate Your Pipes

One of the most effective ways to protect your pipes from freezing temperatures is to insulate them. Pipes located in unheated areas like basements, attics, garages, or crawl spaces are particularly vulnerable. Use pipe insulation sleeves or wrap the pipes with heat tape to keep them warm. This simple step can save you from the headache of dealing with frozen or burst pipes during the winter months.

2. Disconnect and Drain Outdoor Hoses

Leaving hoses connected to outdoor faucets can cause water to back up into the pipes, leading to freezing and potential bursts. Before the first frost, disconnect and store all outdoor hoses. After that, drain any remaining water from the faucets and close the shut-off valve that supplies them. If your outdoor faucets are not frost-proof, consider installing faucet covers for extra protection.

3. Seal Any Gaps or Cracks

Cold air can enter your home through gaps and cracks around doors, windows, and the foundation, increasing the risk of frozen pipes. Inspect these areas and seal any gaps with caulk or weatherstripping. Pay special attention to any areas where plumbing pipes enter or exit your home. Proper sealing will not only help protect your pipes but also improve your home’s energy efficiency.

4. Keep Your Home Warm

Maintaining a consistent indoor temperature is key to preventing frozen pipes. Even if you plan to be away for an extended period, set your thermostat to at least 55°F (13°C) to ensure your pipes stay warm. It’s also a good idea to open cabinet doors under sinks in kitchens and bathrooms to allow warm air to circulate around the pipes.

5. Know How to Shut Off Your Water

In the event that a pipe does freeze and burst, you’ll need to act quickly to minimize water damage. Make sure everyone in your household knows where the main water shut-off valve is located and how to turn it off. This can prevent flooding and reduce the extent of any damage.

6. Check for Leaks and Repair Them

Before winter sets in, inspect your plumbing system for any signs of leaks or drips. Even small leaks can lead to bigger problems when temperatures drop. Fixing leaks now will not only prevent them from worsening but also help reduce your water bill.

7. Drain and Shut Off Your Sprinkler System

If you have an outdoor sprinkler system, it’s important to drain it before winter arrives. Water left in the system can freeze and cause pipes to crack. Most systems have a manual or automatic drain option, or you may need to blow out the system using compressed air. If you’re unsure how to do this, consider hiring a professional to help.

8. Consider Installing a Sump Pump Alarm

If you have a basement, installing a sump pump alarm can alert you to rising water levels before they become a major problem. This is especially important during winter when snowmelt and heavy rains can lead to flooding. Make sure your sump pump is in good working order and test it regularly.

9. Let Faucets Drip During Extreme Cold

During periods of extreme cold, allowing a slow drip of water to flow from your faucets can prevent pipes from freezing. The moving water helps keep pipes from freezing solid. Focus on faucets that are farthest from where water enters your home or those in vulnerable areas.

10. Schedule a Professional Plumbing Inspection

Finally, consider having a professional plumber inspect your system before winter sets in. They can check for potential issues, such as weak spots in your pipes, and recommend any necessary repairs or upgrades to ensure your plumbing is winter-ready.


Winterizing your plumbing is a crucial step in protecting your home from the harsh effects of cold weather.
