What should I do if the water pipe freezes and I don t know where it is frozen?

1. Look at the color. 2. Listen to the sound. 3. Instrument testing.

The color of the frozen plastic water pipe will be darker than the price, and the color can be judged by observation. Find something and knock on the water pipe, and depending on the pronunciation, you can tell where it is frozen. There is also an instrument that can measure this, but it is a bit overkill to buy and measure this.

You can't use too much force when knocking, and of course you don't have to be afraid of galvanized pipes. If it is iron, the sound of the frozen place will be smaller.

1. For thicker pipes, you can use the pipe heating method, that is, after unloading the pipe interface, inject warm salt water into the pipe, and the water pipe will thaw quickly. However, this method is cumbersome and should be considered carefully!

The water pipe is frozen, you can call the maintenance engineer for this, and let them come up and follow the extension of the water pipe to find the frozen location.

1、Defrost naturally

If the water pipe is frozen outside, the sun comes out and let it thaw naturally. But if it rains and snows for many days, the temperature is too low, and the natural thaw is too slow.

Warm water hoses

Pour warm water evenly back and forth over the water pipe. However, it is important to remember that you should not use boiling water to iron the water pipe, so as not to burst the water pipe, due to thermal expansion and cold contraction.

Sawn off and replaced with a new one

If the frozen section of the pipe is very short, you can cut it off and replace it with a new one. If it's too long, it's too wasteful to use this method.

Segmented processing

Use a hair dryer or wrap a towel in the hose and pour it slowly with lukewarm water. If there is still no water flowing out of the watering pipe, it means that the water meter is also frozen, wrap a hot towel around the water meter, and pour warm water to thaw the meter. If the indoor pipe is frozen, you can use methods to increase the room temperature, such as turning on the air conditioner.

Winter water pipe antifreeze method:

1. Keep dripping.

The first anti-freezing trick of the water pipe at home is to turn on the switch of the faucet, open it a little bit, and be able to keep the water of the faucet dripping, the principle is that the water flow will not freeze as long as it has been circulating, unless the weather is very cold, and the water drips into ice, like the water pipe faucet in the Central Plains as long as it is turned on drop by drop, it will basically not freeze, but it is necessary to pay attention to put a bucket in the place where the water is dripping to prevent water waste.

2. Wrap the water pipe.

The second trick is to wrap the water pipe with thermal insulation cotton or waste knitted clothing to prevent freezing, especially in towns or urban areas, as long as there are water pipes, you will often see the water pipe wrapped with thermal insulation cotton, so the first benefit is anti-freezing. The second point can also achieve the effect of sun protection and prolong the service life of the pipe. Moreover, the cost of wrapping insulation cotton is not high, and the home can be considered after installing the water pipe, and the installation of insulation cotton to prevent the water pipe from freezing and cracking.

3. Apply antifreeze.

Applying freeze on the pipe may not really be able to prevent freezing, but after applying antifreeze, it can add a layer of protection to the pipe, and even if it cannot be antifreeze, it can achieve sun protection, so apply freeze on the pipe. Not one of the most effective.

1. You can pour it with hot water. In the future, in case of severe cold weather, you can leave a line of water on the faucet to drip slowly, so that it will not freeze.

2. After the water pipe is frozen, cover the faucet and water pipe with a towel or damp cloth until the ice cubes in the pipe melt.

3. Use hair dryer to blow hair: If the water pipe is PPR material and slightly frozen, you can use a hair dryer to blow hair, and be careful not to blow it in one place when blowing, so that you can thaw the water pipe.

4. Blanch with hot water. However, do not use hot water directly at the beginning, otherwise it is easy to cause water pipe damage. It should be poured with warm water several times before taking hot boiled water. If the freezing is severe, you can pour it several times until the water pipe is boiled.

If the length of the frozen water pipe is only about 50 cm, it is better to directly saw it off and replace it with a new one. How to freeze the water pipe is outdoor or underground water pipe, then it must not be arbitrarily defrosted, you can find a worker who repairs the water pipe, property, water company and other professionals to help repair it.

Knock it, and the sound is different where it freezes.

Generally, it is only the outdoor part that can be frozen.

Knock with a hammer and listen to the sound. Tell which part is frozen by the difference in sound.

1.Turn off the valve, try to release the water in the unfrozen part of the water pipe, and roughly judge the position of the frozen water pipe according to the temperature around the water pipe.

2.Tap lightly with your fingers or a small wooden stick to carefully discern the difference in sound from place to place. Generally speaking, there is a greater chance that the part of the water pipe with a crisp sound will be frozen.

Hope it helps!

As long as it's outside, it's all going to freeze. Because of frostbite in one place, the water in other places cannot flow, it cannot be discharged, and it cannot move, so it can only be frozen. So it's a sound.

Bake from the inside out with electric heaters.

The water pipe does not know that there are the following ways to freeze: pour hot water, blow a hair dryer, and knock it with a hammer.

You can use hot water to pour it over. In the future, in case of severe cold weather, you can leave a little water on the faucet to drip slowly, so that it will not freeze.

After the water pipe freezes, cover the faucet and water pipe with a towel or damp cloth until the ice inside the pipe melts.

Use a hair dryer for hair drying: If the water pipe is PPR material and slightly frozen, you can use a hair dryer for hair dryer, and be careful not to blow it in one place when blowing, so that you can thaw the water pipe.

Hit the head of the spine with a hammer and listen to the sound. You can tell which part is frozen by the difference in sound. Tap lightly with your fingers or a small wooden stick to carefully discern the differences between the sound patterns in each place. Generally speaking, there is a greater chance that the part of the water pipe with a crisp sound will be frozen.

Ways to prevent water pipes from freezing:

Water pipes are "dressed and hatted".

For indoor and outdoor water pipes, water meters, faucets and other water facilities at home, you can wrap a layer with cotton and linen fabrics, plastic foam, etc., and indoor water meters can also use water meter freeze covers; It is also possible to add special insulation materials to indoor and outdoor water pipes.

The water pipe will thaw naturally in 2 to 3 days if it freezes, and the tips are as follows:

1. If the water pipe is frozen, you can bask in the sun for a while after the sun comes out to see if you can turn the water pipe. The premise is that the highest temperature during the day is above 0 degrees, and if the maximum temperature is still below zero, there is little hope for automatic freezing.

2. If the sun can't melt the freezing, then it should be scalded with hot water. However, do not use hot water directly at the beginning, otherwise it is easy to cause water pipe damage. It should be poured with warm water several times, then take a pot of hot boiling water, and pour it evenly back and forth on the water pipe, being careful not to burn yourself.

If it freezes badly, you can pour it several times until the water pipe melts.

3. You can use an electric hair dryer to blow on the frozen water pipe to heat, and when blowing, you should adjust to the big gear, and start with the faucet, sometimes just the faucet is frozen, if the faucet is boiled and the water flows, you don't need to blow the pipe. If the water does not flow, slowly heat the pipes along the faucet until the pipes are boiled.

4. For the thicker pipeline, you can use the pipe heating method, that is, after unloading the pipe interface, inject warm salt water into the pipe, and the water pipe will be thawed quickly. However, this method is cumbersome and should be considered with caution.

5. In order to avoid the water pipe from freezing again, you can wrap the water pipe with broken thick cotton clothes, plastic foam or plastic hand material insulation pipe, etc., from the root of the faucet to the bottom of the water pipe, and then tie it with iron wire to make it stronger. This ensures that the pipes are no longer frozen.

6. If the water in the water pipe is limited, that is, it will not flow after a certain time, then wait until the water is finished and then turn off the faucet, so that there will not be too much water in the water pipe, so that the water pipe will not freeze.

Find and confirm the frozen part of the water pipe in the building, thaw the frozen position of the water pipe, and treat the water pipe after thawing.

Electric heating belts are our most common type of heat tracing. Use the electric heat trace to wrap around the water pipe section, and then power on the upper mouth of the electric heat tracing, so as to ensure that the temperature of the electric heat trace is always at about 10. It is also possible to ensure that the water in the inner water pipe does not freeze.

It is to wrap the outer grip of the water pipe that is easy to freeze around the insulation pipe for insulation.
