Methods of insulation of water pipe

Methods of insulation of water pipe

Anyone who lives in a private house and has its own water supply, passing along the street, probably wondering how to insulate water pipes in the ground, to avoid problems in the winter season.

It is difficult to imagine that in a private home or at the cottage did not have a permanent water supply.

Today the water in a private home is a mandatory attribute of a comfortable stay.

Delivered it into the house through the water system, which in most cases extends from the hole in the street under the ground.

As is known, the water tends to freeze at low temperatures, and if you do not hold the proper insulation of water pipe that runs underground along the street, in the winter, he may simply fail.

should be noted, however, that quite often as a result of the freezing water pipe breaks at all, which means that the system will have to change completely.

avoid all these problems can, if correctly and properly insulate water pipes, even those that run under the floor in the basement.

This job requires a certain knowledge and cost, however, it is mandatory in any private house and a cottage in the country.

Principles of thermal insulation materials

As is known, the minimum depth of the trench for laying the water pipeline is half a meterand deeper than it is, the less risk that the pipe will freeze in the winter.

But in any case, that winter is not to remain without water, it is better to hold additional insulation of pipes with specially designed materials for these purposes.

Particular attention should be paid to the most vulnerable sites, which include the territory near the wells, pumps and wells, and so on.

Materials for insulation

Do not forget about those tubes that are held in the basement of the house, especially if it is not heated.

Earlier trenches with pipes to insulate different improvised materials such as quilted jackets, blankets and so on, but today you can freely buy specially designed for this purpose all kinds of insulation materials.

Despite the abundance of various insulations need, first of all, pay attention to their main characteristics and quality.

Any insulation for water must have a minimum thermal conductivity levels, be durable and resistant to external influences, and in addition, have a water-repellent properties.

Thus, the most popular insulation for the water pipe is glass wool.

It is particularly effective to apply to plastic pipes, but additionally need to use materials such as roofing material or fiberglass.

good performance has basalt insulation, which comes in the form of a cylinder, which facilitates the process of laying.

also often enough trenches with pipes insulated by means of expanded polystyrene, which has high thermal insulation characteristics and can be used several times.

Recently, there was a special heat-insulating paint, which is a pasty mass, to be applied to the surface of the pipe.

You can also note the Microflex pipe that initially come with thermal insulation protection.

For more information on how to properly insulate the pipe extending from the well to the house, told in the video posted below.


Ways of warming

To qualitatively insulate the pipe coming from the well to the house under the ground, it is better to do it at the stage of laying water pipe.Otherwise you will have again to dig a trench, lay the insulation, and so on.

This process takes not only a lot of time and effort, but also quite expensive for Finance.

course, when laying water pipeline from the well to the house you can use a special tube Microflex, which are already equipped with protection, but very often it happens that the need to hold warming already laid pipeline.

In this case, there are several alternative ways to with minimal effort and cost to heat an external water supply.

So, to water in winter is not cold, you can warm it by means of the heating cable.


In this case, when the cable is heating the surface of the pipe itself, thus eliminating the freezing water.

also insulate water pipes can be by means of air.

In this case, you need to use polystyrene or basalt insulation to create a kind of umbrella, which will delay the warm air coming from the ground.

can try to heat the water with high pressure.

To do this, the system should be to embed a special receiver and a check valve, which will be responsible for the pressure in the pipes.Particularly relevant

this method for water coming from the well, since in this case the system has a submersible pump, capable of generating the necessary pressure.

In any case, before you decide on the principle of thermal insulation outdoor plumbing, you need to carefully study the properties of each method and choose the most suitable.

more on warming water system, which is under the ground, talked to the video posted below.


Procedure insulation thermal insulation materials

As if running water is not used for Microflex pipe, you need to how to spend their insulation as soon as possible using appropriate materials.

The material can take the glass fibers, which should be tightly wrap the whole pipe.Next

further settling waterproofing, and for this purpose it is recommended to use roofing material that will act as a kind of protective cover.

In this case, the insulation is better to make a few layers to avoid all possible risks of freezing water pipe that passes under the ground.

Driving insulation

It should be noted that the layer of insulation material will have to withstand the ground, as under the influence of the earth, he will be subject to compression.

For more information about this method of warming water pipe described in the video posted below.

most optimal insulation for pipes passing underground, considered special insulating shell, which can be made from both basalt fiber and expanded polystyrene.

Their installation on the pipe itself is fast enough and does not require great physical effort.

After the material is placed over the entire surface of the pipe, it is necessary to additionally seal with duct tape.In

if water has corners and the nodes, their insulation is carried out using special shaped shells.

The advantage of this method of insulation is that when backfilling the trench ground insulation is not compressed, as well as wet.

In any case, for better use of the water distribution system pipe Microflex that already have additional protection against freezing.

about how to properly insulate the water under the earth, described in the video posted below.


Tips and tricks

Enough effective way to insulate water pipes is to use a special heating cable.It can be routed as in the interior of the pipe and the outside.

This method allows not only qualitatively warm water, but also allows it to defrost when the water is already cold.

Before you connect the cable itself, all the pipe surface must be foiled glue tape.

Then fit the cable itself, which is also the top foiled pasted over with tape and covered with a protective layer.

After this will only hold the connection correctly.

Some ways of warming the aqueduct can be seen in the video posted below.

In any case, before you carry out insulation or running water pipe laid Microflex, it is recommended to make a detailed map of all communications.

At work should pay particular attention to the various connecting elements located on the system.


pipes should be insulated and protected from corrosion throughout its length.

If all the work is done correctly and in a timely manner, the problems with the provision of a private home with water will not be in the winter season.
