Not true. There are many things that a homeowner/resident can do to prevent pipes from freezing. You can seal drafty windows and doors and add extra insulation. You can wrap exposed pipes with a heat tape. You can open cabinet doors under sinks in kitchens and bathrooms to allow warm air to circulate around the plumbing.
2. Your Risks Are Gone As Temperatures Rise
Actually, pipe bursts are usually not discovered until the temperature warms up. The frozen section will often act as a plug, stopping the flow of water until the frozen section warms enough to melt.
3. All Frozen Pipes Burst
A pipe can freeze and not burst. If you notice that the water in a line has stopped flowing, it is best to shut off the water supply to the frozen section and open a faucet to help relieve pressure and give the ice in the frozen section room to expand.
Don’t even consider doing this. The risk of starting a house fire far outweighs the possible benefits.
