: Inspect the visible sections of the pipe for cracks. If you see damage, stop immediately and call a professional. 1. The Saltwater and Boiling Water Method
Keep your home thermostat set to at least 55°F (13°C) even when you are away on vacation. Open cabinet doors under kitchen and bathroom sinks to let ambient room heat reach the plumbing.
| Prevention Measure | Why It Works | |---|---| | | Wrap pipes in unheated areas (attics, crawl spaces, garages) with foam pipe insulation sleeves, UL-approved heat tape, or heat cables. This creates a thermal barrier that keeps the cold air away from the pipe walls. | | Let faucets drip | During extreme cold, allow both hot and cold faucets to drip at a slow trickle. Moving water is far less likely to freeze than standing water. A drip uses very little water but provides significant protection. | | Open cabinet doors | Keep kitchen and bathroom cabinet doors open during cold nights to allow warm household air to circulate around the pipes beneath sinks. This is especially important for sinks located on exterior walls. | | Keep the thermostat consistent | Maintain your home at the same temperature both day and night, even when you are away. Set the thermostat no lower than 55°F (13°C) to ensure pipes stay above freezing. The small increase in your heating bill is far less than the cost of repairing burst pipes. | | Seal air leaks | Use caulk or expanding spray foam to seal gaps around pipes, dryer vents, electrical wiring, and other openings where cold air can enter your home. Even small drafts can cause localized freezing. | | Disconnect garden hoses | Remove all garden hoses from outdoor spigots before winter. Shut off interior valves that supply outdoor faucets, then open the outdoor faucet to allow any remaining water to drain out. Install insulated faucet covers for added protection. | | Keep garage doors closed | If your garage contains water supply or drain lines, keep the garage door closed during cold weather. An open garage door exposes these pipes to freezing temperatures. | how to unfreeze a drain pipe 2021
While it is important to know the correct methods for thawing frozen pipes, it is equally important to understand what you should never do. The following actions are extremely dangerous and can cause fires, pipe explosions, or severe property damage:

Before attempting any DIY thawing, take these essential precautions:
If a pipe is frozen solid, chemical cleaners will become trapped in the standing water. They will not melt ice, and they will create a highly hazardous, corrosive pool of water that makes physical repairs dangerous. 5.

Water sits completely still in your sink, tub, or toilet and refuses to go down.
More people are working from home and cooking more, meaning greasy, warm water goes down drains—then freezes further downstream. Pandemic cooking + polar vortex = perfect drain ice storm.
Wait 5 minutes and repeat the process until the block clears. 2. The Hair Dryer or Heat Gun Method
