To avoid frozen pipes in winter, keep your home heated to at least 55°F (13°C), open cabinet doors to allow warm air to circulate around plumbing, and let faucets drip during extreme cold. Insulate exposed pipes in unheated areas (basements, attics) with foam sleeves and seal air leaks near pipes to prevent drafts.
Ways to avoid frozen pipes
Keep your heating on throughout any spell of severely cold weather. Keep each room in your home warm by setting your thermostat to a minimum of 16 degrees centigrade. If you're worried about your heating bills, turn the radiators down in the rooms you don't use.
"First open the cabinet doors," Butler said. "That allows the heat in the room to get in where the pipes are." Inside the home, faucets should be left dripping to keep water moving through the pipes. "Use a blend of hot and cold, and you can just let that water flow, I mean, you can get it down to a trickle," he said.
Don't use open flame: Torches and open flames can cause fires, damage pipes, and void insurance. Don't power up tools in wet areas: Avoid electric heaters or heat guns near standing water. Don't ignore slow drains: A frozen main or vent can escalate to a sewer backup—get it checked.
When the weather is very cold outside, let the cold water drip from the faucet served by exposed pipes. Running water through the pipe - even at a trickle - helps prevent pipes from freezing.
Yes, you should open the faucet when pipes are frozen; it relieves pressure, preventing bursts, and allows water to flow as the ice melts, helping to thaw the pipe faster, but first, turn off the main water supply to avoid leaks if a crack occurs, then use gentle heat (hair dryer, heating pad) on the frozen section, starting from the faucet end, and keep the faucet open until full pressure returns.
Applications of Removable Insulation Blankets
Designed for easy maintenance and efficient temperature control, these blankets offer protection for essential components like pipes, valves, and flanges, ensuring reliable performance in both high and low-temperature environments.
As long as your house is above freezing you should be fine. However, if it's very very cold out and you have pipes on exterior walls, there are a few extra precautions to take. Open lower sink cabinets so warmer interior air can get to the pipes.
Ping pong balls can help slow ice formation by floating and being moved by wind or pecking, breaking up surface ice, but they won't stop water from freezing solid in very cold temperatures. This method works best in mild frosts (around freezing) by creating constant movement, but in deep freezes, the water will freeze regardless, requiring more robust solutions like heated bowls or insulation.
There have been many reports from doctors that sleeping with the heating on all night can cause your body to overheat much more quickly. The Sleep Charity advises that an ideal bedroom temperature is 16-18 degrees celsius. Temperatures over 24 degrees celsius can impact your sleep and cause restlessness.
Yes, letting a small stream of cold water run from a faucet (especially the one farthest from the water meter) during extreme cold is a recommended way to prevent pipes from freezing and bursting because moving water is harder to freeze than stagnant water, but you should also open cabinet doors, keep your thermostat consistent, and insulate pipes for maximum protection.
For freezing weather, covering outdoor faucets is generally better than dripping them, as covers prevent water waste while insulation protects against freezing; you should shut off the indoor water supply to the spigot first, then cover it with an insulated cover or DIY insulation (towels, pool noodles) for maximum protection, saving dripping for inside faucets during extreme cold or if covers aren't an option. If you can't use covers, dripping inside faucets and opening cabinets helps, but the best protection for outside spigots is proper winterization, notes this DIY guide.
Here are a few areas to consider first when identifying the most cold-vulnerable plumbing in your home:
Slow Running Water
Turning on the faucet and getting a trickle of water is usually bad news. It can mean that there's ice on the inside wall of the pipe. Sometimes, you might turn on the faucet and get no water at all. During freezing temperatures, be aware of any sudden changes in water pressure.
Isopropyl alcohol (70% or 91%) has an extremely low freezing point and is relatively inexpensive, which makes it a good deicer. (And you might still have a bunch stocked up from the pandemic!) A good way to use it is to mix about 2 tablespoons with a half-gallon of water and put it in a spray bottle or bucket.
Letting the Water Run
If there is no excessive water pressure, there is no burst pipe, even if the water inside the pipe freezes. A dripping faucet wastes some water, so only pipes vulnerable to freezing (ones that run through an unheated or unprotected space) should be left with the water flowing.
If your pipes freeze:
If you detect that your water pipes have frozen, turn off the water at the main shut-off valve in the house. NEVER try to thaw a pipe with a torch or open flame. You may be able to thaw a frozen pipe with the warm air from a hair dryer.
If temperatures fall to 20 degrees or lower and will stay there for an extended period of time, drip all the faucets in your home, especially those that are connected to pipes that run in exterior walls, as they are less insulated from the cold. Make sure to drip both hot and cold water faucets.
If only cold water is frozen but hot water works, let the hot water run for about 20 minutes, as this might help thaw the frozen cold water pipe.
