Quick Answer: How To Thaw Frozen Main Water Line

Make sure the hot water is turned on, and the cold water turned off. Once the ice has thawed enough to allow a flow through the pipe, turn all other faucets to a trickle. This will keep the hot water flowing. Allow the frozen pipe to completely thaw and the water to flow freely before turning it off.

What to do if main line is frozen?

One of the most commonly recommended fixes for a frozen sewer line is to pour very hot water (not boiling) down the drain in order to thaw the blockage.

Will pouring hot water down drain unfreeze pipes?

In most cases, you can unfreeze a frozen drainpipe by pouring hot water down it. Fill a pot with a half-gallon of water, and heat it on the stove. When it begins to boil, carefully remove it from the stove and slowly pour it down the drain. This may be enough to thaw the ice and completely clear your drain.

How long does it take to thaw frozen water pipes?

Should I leave faucet on if pipes are frozen?

The combined pressure of the expanding and shrinking ice blockage and the increasing water pressure behind it can cause pipes to leak or burst. This is why you’ll always want to leave a faucet on if a pipe is frozen completely, even if there’s not enough water flow for a drip.

Will pipes unfreeze on their own?

Will Pipes Thaw on Their Own? Technically yes, but the “wait-and-watch” method carries risk. As that ice begins to thaw, any water caught between the faucet and the ice will cause increased pressure within the pipe.

Are my pipes frozen or is my water shut off?

If they have a loss of water too, it may be the result of a main break. But if they have running water, it’s likely your pipes have frozen. Turn off the water immediately at the main shut off valve. Open the faucet so that water will flow through the pipe once the area is melted.

Can I pour boiling water down a frozen pipe?

Never pour hot water on frozen plumbing or try to thaw pipes with a blowtorch. The hot water usually freezes on the outside of the pipe, and the torch can cause frozen pipes to explode if steam is produced. Also, do not strike pipes in an attempt to break up the ice, as hammer blows can cause pipes to crack.

What do plumbers do for frozen pipes?

If the pipes are frozen but have not burst, a plumber can remedy them by applying a heat gun to thaw them. For an interim solution, a homeowner could use a hair dryer to start the thawing process. A plumber’s main role and concern in this situation is to identify and fix the problem that caused the pipes to freeze.
