The plastic water pipe is frozen, can it be scalded with hot water?

No. If the water pipe is frozen, do not directly scald it with boiling water, it is easy to cause the water pipe to burst because of the large temperature difference between cold and heat, so that the water pipe can be evenly poured on the water pipe with warm water, so that the frozen water pipe can be evenly heated, so as to have the effect of thawing. You can also put a towel on the water pipe, at this time you can pour hot water evenly on the water pipe, do not remember to pour water directly on the water pipe, this is very dangerous.

Precautions for anti-freezing of plastic water pipes.

To make a protective film for the water pipe, such as applying a layer of antifreeze to the outside of the water pipe, if you brush a layer of paint on the outside of the antifreeze, the protective effect is better.

Without wasting water, open the faucet slightly to keep the water flowing in the pipes.

After applying antifreeze, you can also wrap a layer of torn quilt, cotton and linen fabric or plastic on the outside of the water pipe, which can play a role in heat preservation.

OK. It's not bad.

Pouring hot water is only a short contact, and it is not boiling the tube in hot water.

Yes. As long as the temperature is below freezing, it may freeze and crack. Water pipes freeze and burst because the water expands in volume when it freezes, and one of the conditions for freezing is when the temperature is less than or equal to freezing.

During the freezing process, the freezing point of the water in the pipe decreases as the pressure increases (the inlet must freeze first). Some plastic pipes have a certain elasticity and can accommodate the volume of ice expansion without bursting within a certain range. <

How to prevent water pipes from freezing and cracking in winter: 1. Wear "clothes" and hats, the temperature is low, and it is snowing in many places. Especially in the north, when the temperature reaches zero degrees Celsius, the water begins to freeze, so for water pipes and other water equipment, it is necessary to wrap a layer of cotton and linen fabrics, plastics, foam and other objects to keep warm.

2. Increase the room temperature: When it is colder in winter, the room temperature is also relatively low, and the balcony, kitchen, bathroom and all doors and windows facing north should be closed at night to increase the temperature of the room as much as possible. For high-rise residences, water facilities such as pipes and water meters installed in the corridor, please close the doors and windows of the corridor in time to keep warm, which can effectively avoid freezing and blockage of the facilities; The door or lid of the water meter box of the pipe well or the outdoor buried water meter box should be closed.

3. Emptying of the remaining water from the water pipe: When it is cold in winter, close the water meter valve at home before going to bed at night, and then open the faucet to drain the water in the water pipe, and the water pipe will not freeze if there is no water in it.

01 Pour warm water into the pipe. If the water pipe can get water, you can pour some warm water appropriately, so that the ice in the water pipe can thaw, which is also a very good method, but the water temperature should not be too high, otherwise it will have a great impact on the water pipe.

02 Use towels. If you don't find it troublesome, you can use a towel to thaw the water pipe, you can dip the towel in hot water and then use a hot towel to thaw it, which is relatively gentle for the water pipe.

03 Use a hot water bottle. In winter, there are usually hot water bottles in the home, so you can use a hot water bottle to thaw the water pipes, which is also a relatively easy way to keep the water pipes from freezing very stiff.

04 Use a hair dryer. If the water pipe is frozen, the water will not flow out if there is ice in it, so you need to blow it with a hair dryer so that the ice in the water pipe can be dissolved and you can use it.

For the frozen water pipe, do not twist it vigorously, do not use pliers and other tools to start hard, and do not use fire or boiling water to pour it directly, otherwise it is easy to damage the faucet and cause the pipe or water meter to burst. The correct way to do this is to wrap the faucet in a towel and pour warm water along the faucet to thaw it down the pipe, or use a hair dryer to blow the faucet.

Precautions for freezing water pipes: 1. Protect the billing water meter, remove the water in the water meter well, and wrap the water meter and the front and rear water pipes in the meter well with insulation materials to expose the dial for easy inspection.

2. Close the doors and windows at night to ensure that the indoor temperature is above 0. In case of severe cold weather (below -3), in order to keep the faucet from freezing, the most effective way is to unscrew the faucet slightly after using the water, keep the drip or line flow state, and ensure the flow of tap water in the water pipe.

Generally speaking, qualified PPR tubes will not freeze and crack under the temperature of our living conditions (including outdoor). Of course, bursts caused by excessive water pressure are not included. The main cause of freezing and cracking is that the water in the pipe will become larger after turning into ice, and the expansion will lead to the rupture of the water pipe.

Whereas, the rate of volumetric expansion of water into ice is certain. Therefore, the PPR tubes of regular manufacturers can withstand this change.

Summary. Hello, dear, the question you asked, here is the answer to you as follows: dear, the plastic pipe should not be able to open the water pipe if it is glued.

Hello, dear, the question you asked, here is the answer to you as follows: dear, the plastic pipe should not be able to open the water pipe if it is glued.

1. How to disassemble the glue sticky water pipe 1. If the glue is stained on the water pipe, you can use a hair dryer to blow it, directly adjust it to the hot air stop, and the glue melts, or through thermal expansion and cold contraction, because the viscosity of the glue will weaken after it is heated, and then pour boiling water, and the glue on the water pipe can be washed clean by a few minutes, and finally wiped clean with a rag. This method consumes more hot water, but it does not damage the water pipes and can be reused in the future. 2. If it really doesn't work, you can take the simplest and most violent way to cut it directly with a saw.

However, when sawing, you must pay attention not to damage the water pipe, but if you are willing to hold it, it will definitely damage one of the pipe fittings. Sawing along the interface of the tee, then digging out the pipe connected to the tee, and replacing it with a new tee connection.

3. You can also dissolve the stupid water of rubber pants through some chemical components, for example, you can apply acetone solution, because glue is a kind of resin orange glue, which can be effectively dissolved through this organic solution, and then poured it with hot water to remove it.

If you want to disassemble the glue sticky water pipe, we can melt the glue first, and then the disassembly will be much easier, or directly take the way of directly sawing off the interface, and you can also disassemble the water pipe.
