Question: How To Thaw 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.

How long does it take for underground pipes to thaw?

If you choose to unfreeze your own pipes, how long it takes for pipes to thaw depends on whether the pipes are exposed, enclosed, or underground. It will take roughly 30-40 minutes of using a heat source to thaw exposed pipes.

Can main water line freeze?

The water mains that carry water to service lines are highly pressurized and fast moving, and therefore extremely unlikely to ever freeze.

How do you defrost pipes quickly?

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.

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.

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 themselves?

Pipes will eventually unfreeze on their own naturally, but this takes far more time and before thawing occurs the freezing could become much worse. This could eventually lead to the pipe bursting and causing significantly more damage. It’s better to proactively thaw a frozen pipe size than let it persist.

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.

How do you Unthaw frozen pipes without bursting them?

If you attempt to thaw the frozen pipes yourself, keep the following tips in mind: Keep your faucet open. Apply heat to the section of the pipe that is frozen. Know what not to do. Continue applying heat until water flow returns to normal. Take swift action if the frozen pipes are located inside an exterior wall.

How do I unfreeze my outdoor pipes?

Apply heat using heat tape or a heat blanket to thaw the pipe. Leave the pipe exposed to surround it with warm air. Leave the taps that run from the supply line open, so water can drip as it thaws. Once water starts flowing from the faucet normally, the water has thawed.

At what temperature will frozen pipes thaw?

What Temperature Do Pipes Unfreeze? Your pipes will begin to thaw naturally once the temperature rises above freezing. But if cold weather persists and does not go above 32 degrees Fahrenheit, you could be in for an awfully long wait.

How do I know if my main water line is frozen?

The clearest sign that you have frozen pipes is if there is a complete lack of water coming out of your faucets and fixtures. This means that the water in your supply lines has frozen solid. In some cases, due to a partial freeze, you may still see a slight trickle of water.

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.

Do you drip hot or cold water to keep pipes from freezing?

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.
