Stay warm out there. And for goodness’ sake, don’t pour bacon grease down the sink.
Frozen drain pipes are a common winter problem. Below are safe, practical steps and examples to locate, thaw, and prevent frozen drain pipes. Assume standard household PVC, copper, or galvanized drain lines; if you suspect a burst pipe, stop and call a plumber.
Always start heating from the faucet side of the clog and work your way toward the blockage. This allows the melting water to drain out instead of getting trapped behind the ice. how to unfreeze a drain pipe 2021
A slow, steady drip keeps water moving, making it much harder for it to freeze.
Never use an open flame, which can damage pipes and create a fire hazard. Instead, use a hairdryer, heat gun on a low setting, or wrap the pipe in heating tape or heating cables to slowly thaw it. Stay warm out there
Once you locate the blockage, use one of these DIY methods to melt the ice safely. Always start with the gentlest method first. 1. The Hot Water and Salt Method
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: Below are safe, practical steps and examples to
Before applying heat, you must find the exact location of the ice blockage. Drains usually freeze in specific, vulnerable areas where the pipe is exposed to the coldest temperatures.
If you attempt these methods and water still will not drain, or if you notice a crack in your pipe, shut off your main water valve immediately and call a licensed professional plumber.
The winter of 2021 brought unprecedented cold to many parts of the United States, with millions of Americans experiencing power outages alongside record-low temperatures. This created unique challenges for homeowners dealing with frozen pipes. Several important lessons emerged from the 2021 winter storms that are worth highlighting:
| 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. |
