Keep your pipes in tip-top shape all winter long
As temperatures start to drop in the late fall, there’s an increased risk of significant home damage: frozen pipes. If the water in your pipes freezes, it can cause pipes to burst, leading to potentially massive and costly damage. Luckily, you can prevent frozen pipes with these few precautions.
1. Insulate Pipes
Insulate your pipes before chilly weather sets in. Winterizing your pipes is an essential step in your fall home maintenance process to prevent serious damage during the coldest months of the year.
Pipe insulation costs $1 to $4 per linear foot for professional installation.
To DIY, expect to spend $1 to $7 per 6 feet of pipe insulation material.
Insulate pipes in unheated spaces, particularly attics, basements, and garages.
Find the right insulation for your pipes based on the R-value and size. The higher the R-value, the better the insulation. Most pipe insulation is either 0.5 or 0.75 inches in diameter, so check your pipes before ordering.
2. Open Cabinet Doors
One easy way to help keep pipes from freezing is to let the warm air in your home circulate around the pipes. When you have the heat going, open up cabinet doors in the kitchen and bathrooms. This way, warm air can better reach the pipes in or behind the cabinets.
3. Close Garage Doors
While you want to open cabinet doors, you should close garage doors if water supply lines run through the garage. When it’s freezing outside, that cold air will enter the garage if the door is left open. This will make the temperature in the garage drop even lower, potentially leading to frozen pipes.
4. Keep the Heat On
If you’re going on vacation or to visit family over the holidays, keep the indoor temperature set to at least 55°F to prevent freezing. Many people set the thermostat lower at night to reduce utility bills, but a frozen or burst pipe will cost you far more. Keep the temperature at a minimum of 55°F, even at night.
5. Open Interior Doors
While closing the bedroom or bathroom door after leaving the room might be a habit, try to break it come winter. Leaving interior doors open as much as possible will allow warm air to circulate evenly throughout the home. This can help keep enclosed pipes warm enough to avoid freezing.
6. Let Faucets Drip
When the outside temperature reaches 20°F or lower, you’ll need to let some of the faucets in your home drip to help prevent freezing. Moving water creates energy and friction, which decreases the possibility of frozen pipes.
Identify faucets connected to pipes that have frozen previously and those that are exposed or against outdoor walls.
Turn on these faucets to a drip or trickle.
If water pipes for both hot and cold water are exposed, turn on both to a trickle to prevent either line from freezing.
7. Apply Electrical Heating Tape
Electrical heating tape can help warm pipes before they get too cold. Heating tape is actually a heating cable wrapped in electrical wire that plugs into an outlet to generate heat. There are manual or self-monitoring electrical heating tape options.
Manual electrical heating tape: Wrap tape around the pipes before a cold snap, then plug in to activate.
Self-monitoring heating tape: This heating tape uses a sensor to determine when pipes are too cold. The sensor will trigger the heating tape to turn on and warm the pipes.
How to Thaw Frozen Pipes
You might be too late to stop the pipes from freezing, but you can help them unthaw to prevent serious damage. However, if you notice a broken pipe, shut off the main water valve and find a local emergency plumber immediately.
Thaw pipes inside your home by turning up the thermostat. Open up doors and cabinets to help warm air circulate.
Use a hairdryer to heat 12-inch sections of the pipe until it is no longer frozen.
Aim a space heater toward the pipes.
Wrap exposed pipes in hot, damp towels. Replace the towel frequently as it cools.
