Tips to Winterize Plumbing and Pipes

Water in sink

Follow these steps to winterize your home plumbing before the cold sets in. 

Contrary to popular belief, pipes don’t burst at the point where water freezes, but somewhere between the freeze and a closed faucet, such as the kitchen faucet or washing machine. When the pressure builds due to ice blockage, it has nowhere to go but through the pipe walls, leading to extensive water damage. Winterize your home plumbing, stop frozen pipes before they happen and prevent expensive water damage by properly insulating the plumbing pipes in your home.

1. Pipe insulation

Your pipes are more susceptible to freezing damage when temperatures drop to 20 degrees Fahrenheit or below. Pipe insulation provides your first line of defense against cold temperatures and frozen pipes. Living in Tucson, these winter temperatures aren’t norm, so we must take extra caution when adding pipe insulation. For pipe winterization, add a thicker layer of insulation around your pipes.

Insulate the pipes in all unheated areas, as they are most likely to freeze. A hardware or plumbing supply store should have the insulation and tools you need. Wrap the pipes in insulation tubes made of polyethylene or fiberglass. Measure the outside diameter of your pipes to make sure you purchase the correct size of tube. Take extra care with pipes that have frozen during previous winters or have been repaired in the last 12 months, as these pipes are more susceptible to damage. Wrapping pipes in heat-tape prior to insulating adds an extra layer of protection, but make sure you follow the manufacturer’s instructions when using heat-tape to avoid damage.

2. Keep a dripping faucet

On nights when the temperature is expected to drop below freezing, turn on faucets along the exterior walls to create a small, steady drip. This eliminates pressure that can build between the faucet and an ice blockage, so even if a pipe freezes, it may not burst. 

Your home plumbing could pay a big price if your house isn’t prepared for winter. Learn how to save cash and keep pipes from freezing.

3. Open cabinets

You can stop frozen pipes by introducing more heat. Open all sink-based cabinet doors along exterior walls to allow more heat to reach the pipes.

4. Fix exterior cracks

Note any cracks or holes along the outside walls and foundation of your home. Filling holes and cracks with spray foam insulation and caulking can help stop the cold air from coming into contact with your water pipes during extremely cold weather.
