The plastic pipes of cold water in the toilet are sweating. How to remove condensate from cold water pipes

Like it or not, but condensate on pipes through which cold water flows is a common phenomenon. The same laws will have to be opposed to the laws of physics. It seems, well, you’ll think, the pipe has dampened once or twice. But then one of the household asks: “Where does the mold come from?”.

Condensation on the pipes in the toilet

Moisture condensation occurs either due to the high content of vapor in the air, or due to temperature differences. If condensation settles on the pipes in the toilet, check the ventilation first. The easiest way is to leave the toilet door open at night. If you find dry pipes in the morning, the problem is insufficient ventilation.

The second common reason is a constant leak from the tank. The water in the pipe does not have time to warm up and is constantly replaced by cold water. The pipe cools even more and becomes covered with condensate droplets. The inlet valve of the tank and taps should be checked and put in order.

Of course, the riser pipe can also “sweat”. This means that one of your neighbors has the leak problem described above. As a temporary measure, several turns of bandage can be wound around the pipe, and the end lowered into some kind of container. The main thing is to pour out the accumulated water in time. Of course, there is nothing more permanent than a temporary phenomenon, but someday you will get tired of controlling the saving jar and you will take care of the thermal insulation of the pipe. It can be wrapped with unnecessary rags, but this is not very aesthetically pleasing. On sale there is a special thermal insulation made of a porous material that looks like foam rubber. A thick-walled soft tube with a longitudinal slit is easily installed on the weeping area and the problem can be considered solved. Please note: thermal insulation should be installed on pre-dried pipes.

Condensation on the pipes in the bathroom

If the condensate settles on, you should proceed in the same way. The riser gets wet - the neighbors from above are to blame, the pipe going to plumbing device- faucet bogs down. Similarly, check the "guilt" of the ventilation in the inlet. In the same way as in the first case, it is advisable to protect the pipes with thermal insulation. The chemical industry offers another option - the Grafoterm tool. A dry pipe must be rubbed with the preparation and the resulting film will prevent the formation of condensate. Chemical treatment should still be considered a temporary measure and not relax. If there is no condensation on the pipe, this does not mean that the air humidity has magically stabilized and you can not look for the root cause.

How to remove condensate from pipes

Thermal insulation deserves a separate discussion. As mentioned above, it is possible to remove condensate from pipes if they are dressed in a special insulating material. But if there is none at hand?

can save the situation polyurethane foam. You need to buy a corrugation with a diameter slightly larger than your problematic pipes, cut it into pieces that are easy to use and along the length to put on the pipes. On this mockery of oneself and the material comes to the finish line. Fill the annular space with mounting foam and, in fact, the mission is completed.

There is another way to organize thermal insulation from improvised means. You will need:

  • sanding paper;
  • rust converter (phosphoric acid);
  • thick strong thread;
  • strips of fabric;
  • epoxy putty;
  • putty knife;
  • acetone.

A wonderful way to find a use for old sheets along the way. They will have to be mercilessly cut into bandages 5-6 cm wide and rolled into rolls. The more bandages you prepare, the less often you have to interrupt.

The pipe must first be sanded to ensure reliable adhesion of the material to the pipe. Then moisten a rag with acetone and wipe the pipe to degrease the surface. The next step is rust converter treatment.

After the pipe dries, epoxy putty is applied to it. It should resemble thick paint and not drain. The material hardens quickly, so you have to work quickly. The prepared pipe is wrapped with a cloth, starting from the bottom and pulling the strip well. The turns of fabric should overlap each other and be impregnated with putty. Tie the last loop tightly with a thread.

When the first layer of putty is completely polymerized (see instructions), two or three more layers of fabric insulation are applied in the same way. The work ends with the application of an epoxy layer. After that, you need to wait until everything dries. Then the pipe should be sanded and painted to match the color of the wall.

Condensation can almost always be observed on cold water pipes. This phenomenon not only spoils to some extent appearance bathroom, but can cause serious problems. Constantly wet tubular elements have a limited service life.

Therefore, such a problem should be solved very quickly. In this case, questions arise, what to do if drops of water are found on the pipeline and how to remove condensate from the pipes cold water. First, there is no need to over-dramatize the situation. Secondly, you need to familiarize yourself with all the methods for eliminating this problem. Third, choose the most best option and put it into practice.

Causes of condensation

Condensation on cold water pipes can appear for the following reasons:

  • The presence of a source in the room high humidity.
  • Insufficient ventilation.
  • Water supply pipes have poor quality thermal insulation.
  • Temperature changes. For this reason, in the summer, there may be a stronger formation of condensate, which simply flows down the surface of the pipes.

The main part of the reasons for the formation of condensate does not require explanation. As for the first item from the list, some clarifications are required.


Sources of high humidity include the following:

  • Problems arising in the process of functioning of communication systems and buildings. These can be steam from cooking, evaporation from wet laundry, a flooded basement, a pipe failure, and a vent clogged with debris.
  • Defects in the building resulting from a violation of construction technology.
  • Geographical features of the region: the proximity of large bodies of water or high levels of humidity in combination with rocky soil, which contributes to the formation of condensate.
  • Adverse natural phenomena: sleet, heavy rains or humid climate of the area.

Prerequisites for the appearance of condensate on cold water pipes

In most cases, condensate appears on pipes located in bathrooms. Despite the specifics of these rooms, it is not only for this reason that the pipes become wet.

There are a number of factors that can cause condensation to form on the pipes in a toilet:

  • Insufficient ventilation. To determine that condensation appears precisely because of this, it is enough to leave the doors to the toilet open at night. If the pipeline turns out to be dry in the morning, then repairs should be done. ventilation system and make it better.
  • Constant flow of water in the tank due to a malfunction of the valve. This leads to the fact that the pipeline begins to cool, resulting in a greater accumulation of condensate on its surface. A simple repair will fix the problem inlet valve and tank taps.
  • Leak in the toilet of the neighbors living on the top floor. In this case, you need to inform the owners about the situation. In their absence, you can temporarily eliminate the condensate with your own hands. To do this, the section of the pipeline, on which the accumulation of water drops is found, is wrapped with a bandage in several layers and one end of the winding is lowered into a container, the accumulated water is regularly poured out. See also: "".


The accumulation of water on the cold water pipes in the bathroom can occur in the following situations:

  • Incorrect location of the water supply system. If the pipes of hot and cold water supply pass close enough to each other and do not have thermal insulation, then accumulation of water droplets is observed on the elements through which cold water flows. The way out of this situation is to ensure high-quality thermal insulation of pipe elements using suitable materials.
  • Mixer failure. If water constantly drips from the faucet, the overall temperature drops. working environment, which leads to cooling of the pipes and the formation of condensate on their surface. Repairing the mixer will help solve the problem.

How to remove condensate, how to wrap pipes

For those who have encountered such a phenomenon, the question immediately arises of how to wrap the pipe so that there is no condensate. There are several ways to prevent the appearance of water droplets on the surface of cold water supply pipes, one of which is thermal insulation. This option is considered the most effective, as it eliminates the cause of their appearance - a temperature drop. The easiest and fastest way to resolve the issue is by means of an insulating tube, cutting it lengthwise for convenient placement. For the manufacture of the tube, polyethylene foam, energy flex or thermoflex is used.

There is another way to deal with condensate on tubular elements, but it is considered more complicated. Using this option requires the following materials: epoxy putty, acetone, rust remover, sanding paper, spatula, nylon thread and strips of fabric about 5 cm wide.


The process looks like this:

  • The pipe is cleaned with sanding paper to improve surface adhesion.
  • Degrease the skinned area with acetone.
  • The surface is treated with a rust remover and allowed to dry (read also: "").
  • A thick epoxy putty is applied to the pipe and wrapped with strips of fabric. The edges are fixed with a thread.
  • Another layer of putty is applied on top and again wrapped with a cloth.
  • Cover the fabric with putty and leave to dry completely.
  • After all layers have dried, the pipe is sanded and painted.

In the event that drops of water appear as a result of a malfunction of the plastic pipeline, you can independently replace the damaged section of the pipeline with a new elbow. Metal pipelines can only be replaced by plumbers with special equipment and skills.


To prevent condensation on plastic cold water pipes, the following types of insulating materials are recommended:

  • Styrofoam or expanded polystyrene is considered a universal insulation for pipelines made of polymer materials. It comes in the form of a shell, consisting of two halves. They are connected to each other by means of a tongue-and-groove lock. The use of such insulation is quite simple: the shell halves are put on the pipe and fixed with adhesive tape.
  • Mineral wool for pipeline insulation is produced in rolls, which greatly simplifies the use of this material.
  • Polyurethane foam refers to heaters with high insulating characteristics. The temperature range of such material is quite wide, from -160 0 C to +150 0 C. Almost all polypropylene pipes have such a layer, it is formed on products during the production process. In this case, the thickness of the insulation reaches 5 cm.

Chemical elements that help get rid of condensate

Products of the chemical industry help to protect cold water supply pipes from condensate formation: Stermizol, Korund, Teplomett and others.

The use of these insulating compounds implies the following actions:

  • The pipe is cleaned of dirt and rust.
  • Apply a layer of primer for better adhesion of the insulation to the surface and leave to dry.
  • Using a roller, brush or spray, cover the surface with a protective mixture. The most effective is the application of 5 layers of insulation, and each layer must dry well before the next application. Optimal time drying of such mixtures is about 1 hour.
  • A special fixer helps to extend the service life of a heat-insulated pipeline, which in parallel will make the pipes more attractive.

Which method to use to deal with condensate on cold water pipes depends on the reasons for the formation of this phenomenon and the specific operating conditions. It is very important to consider how often the problem occurs, as well as at what stage it is.

Condensate drain - condensate trap

To drain the resulting condensate into automatic mode float trap is used. This device is installed at the outlet of the apparatus that provides heat exchange, including water heaters and heaters. Through such technical device the water accumulated in the system simply evaporates.

Steam traps fall into three main groups:

  • Combined devices.
  • thermostatic.
  • Float.


The operation of float type steam traps is based on the use of the difference between the density of condensate and steam. These devices are very popular due to the large number of positive characteristics.

The main advantages of this type of device are the following:

  • High degree of reliability.
  • Excellent performance figures.
  • Possibility of work at the minimum loadings.
  • No need for condensate cooling.
  • Resistant to sudden temperature changes.
  • Uninterrupted operation under increased loads.


It is also impossible not to note the optimal energy saving indicators of thermal systems with float-type steam traps.

To deal with condensate, you can choose any of the following methods. In most cases, their use helps to eliminate unwanted moisture. If these options are not effective enough, it is possible to get rid of the formation of condensate on cold water pipes by waterproofing all surfaces of the room. Quality performance work of this type is possible only with special knowledge and skills.


Droplets of condensate on cold water pipes are common, especially in summer when the air is heated to high temperatures. Droplets collect in streams and often puddles form on the floor next to the water supply pipe.

Causes of condensation on pipes

During the repair of the premises, especially with constant high humidity, it is worth taking care of communications in advance. Condensation on pipes, both metal and plastic, can occur for the following reasons:

  1. Leakage plumbing as a result of improper installation, or in the process of wear.
  2. Poor ventilation, incorrect organized system hoods humid air. Blockages in the ventilation system will lead to excess moisture on the surfaces of the room.
  3. Leak in the plumbing system, neighbors' toilet bowls.
  4. A sharp temperature drop in the room where condensate collects. The situation is especially deplorable in the summer, when the surface of the pipeline is literally.
  5. Configurations of distributing cold, hot water supply. If they are not thermally insulated, while located close to each other, condensation is inevitable (which is why it is so important).

How to get rid of condensation?

If moisture accumulates on the riser, it is possible that the neighbors have a mixer, other plumbing. This can be tested at night, when the characteristic sounds of flowing water are heard in silence. The problem with ventilation is observed when the windows are locked, especially those equipped with metal-plastic bags. Checking the operation of the system is easy.

It is enough to take a sheet of paper, attach it to the hood, clogging the windows, then do the same with the doors open. If there is no ventilation, the visual effect is obvious.

If moisture is concentrated on the apartment's wiring pipes, the reasons may be as follows. Faulty plumbing fixtures directly in the apartment may be to blame. The second reason is poor air circulation, especially in rooms with constant high humidity.

If the cold water pipe leading to the plumbing gets wet, the faucet, the shower faucet, the inlet valve of the tank in the toilet are to blame. When the riser is constantly getting wet - you need to look for a problem water pipes upstairs neighbors. If the ventilation is clogged, it is worth checking the air circulation in it.

How to eliminate condensate?

You can get rid of the problem in several ways:

  1. Check the hood, remove debris, cobwebs from there, then buy a compact fan, install it instead of the ventilation grill. Manufacturers offer a wide range of similar devices, different in price, power.
  2. Isolate the water supply system with special insulating tubes with a cut, which are available in building supermarkets. They are made of energy flex, polyethylene foam, the ends are fixed with permanent metallized tape. This method is the easiest, fastest, but before insulating the pipeline must be thoroughly dried.
  3. Complete isolation will provide the following method. First, the pipe is sanded, after which the surface is wiped with acetone, then with a rust converter. After drying the pipeline, it is covered with epoxy putty and quickly wrapped with strips of fabric in 2-3 layers, the edges of the fabric are fixed with a clamp, wire. Then the epoxy putty is applied again, after drying, the surface is sanded, covered with paint.

Methods for protecting metal pipelines

If on metal pipes cold water supply does not eliminate condensate; over time, corrosion will cover them. What can be done in this case:

  1. First, the surface of the pipes is cleaned of rust, then dried, covered with drying oil, oil paint.
  2. You can use carbolate, a paste-like mass for sealing cracks in floors and walls. The composition is applied to the surface with a 5 mm layer, left to harden for 24 hours. After that, it is sanded with fine-grained sandpaper, painted with oil paint.
  3. Protective primers can be used, consisting of zinc dust diluted with drying oil, epoxy varnishes. They cover the surface of the pipe, after which they are painted with paints and enamels.
  4. The pipeline in the toilet can be coated with a composition based on drying oil, minium in a ratio of 20:80 or primers such as GF-031, FL-03K, FL-053, GF-021.

If we are talking about the bathroom, here for painting hot pipelines, heated towel rails, oil-resistant enamels are used, for cold ones - any enamels, paints.

How else can you deal with condensation?

The following is a good way to fix the problem. It is necessary to put on the pipeline a corrugation with a diameter larger than that of the pipe, then fill the cavity between the surfaces with mounting foam. If puddles form on the floor, in the place where condensate accumulates, a sleeve made of pipes several diameters larger than the wiring itself will help get rid of them. The system is simple, while it will not interfere with the repair, replacement of the pipeline in the future.

Moisture absorbers sold in supermarkets household appliances is a great way to deal with a problem. They are a plastic box inside which an absorbent tablet is placed. The absorber will relieve not only of condensate on the pipe, but also eliminate humidity in the entire room.

A more expensive option is to install an air conditioner with climate control, which will ensure the optimal level of humidity.

It is advisable to waterproof the floor of the bathroom, toilet, which will help to cope with the problem of condensation on pipes and surfaces. If this method of repair is not feasible, it is worth opening windows after taking a hot shower, taking a bath, opening the bathroom doors. The circulation of cool air will quickly eliminate the accumulated condensate, help to effectively cope with moisture on the pipes.

Based on the practical experience of dealing with condensate on pipes, the masters advise the following:

  1. Yuri Rogov, plumber, recommends buying Gofroterm, special compound sold in specialized stores. It is applied to the surface of the pipe, after which a strong elastic film is formed on it, which prevents the formation of moisture.
  2. Andrey Kazantsev, foreman of the production site, advises to purchase liquid thermal insulation, which, like paint, is applied to the dried, cleaned surface of the pipeline. According to him, this method is better than thermoflex, other insulating materials.
  3. If the ventilation, plumbing, plumbing is in good order, the cause of the accumulation of condensate may be the temperature difference between the pipe and the air. Locksmith Nikolai Korotkov advises in this case to conduct insulation. To do this, you will need long covers of polyethylene foam, or merylon, hollow inside, which are sold in hardware stores. They are put on the pipeline, fixed at the bottom with a wire, a clamp.

You can get rid of fogging of the cold water supply pipeline different ways. Which one to choose should be determined after analyzing the situation.

Plumbing work, if you have a tool, experience, you can do it yourself, as an option - seek help from specialists. Read also the material about and you will be interested in the material about.

The occurrence of condensate on the pipes of cold water supply is quite common. Both metal and plastic pipes most covered with moisture in the summer: to effectively overcome this problem, it is important to understand the exact cause of its origin.

Why condensation occurs

The main reasons for cold pipe humidification are:

  1. If we are talking about a cold water riser, in this case, condensate will form on an ongoing basis, up to the appearance of puddles on the floor. The reason may be a leak in one or more pipes in the upper neighbor's apartment. Often the whole thing is in an unreliable toilet tank. To clarify this, it is best to choose the night time, when it is possible to hear well the fall of drops along the sewer riser. Condensation on pipes hot water usually does not occur.
  2. When absent exhaust ventilation. The same may be due to interruptions in her work. This problem often affects new buildings or dwellings where there are metal-plastic windows: in such cases, there may be no hood if the windows are tightly closed. To determine the difference, a simple experiment is carried out by applying a newspaper to the ventilation grill, opening and then closing the windows. If there is no exhaust ventilation, sometimes it turns out to be powerless and additional fan.
  3. If condensation is observed on the plastic pipes that are included in the apartment wiring, quite often the reason lies in the breakdown of the plumbing fixture, with insufficient or completely absent hood.

Condensation on the pipes in the toilet

Condensation on the cold water pipes in the toilet can occur due to high humidity or temperature fluctuations. If this problem is detected, ventilation is first checked: for this, you can leave the door to the room open at night. If during this time the moisture on the pipes disappears, then it's all about poor ventilation. Another potential possible reason- constant flow of water through the tank.

This leads to the effect of cooling the pipe, since there is no time left for heating the water inside it. As a result, the surface of the pipe becomes a comfortable place for moisture condensation. Usually, after repairing the taps and the inlet valve, the problem disappears.

Condensation in the bathroom on cold water pipes

Before starting repair measures, it is important to determine exactly the cause of the problem, which usually consists of the following:

  • When the riser pipe gets wet, the whole thing is usually the flow of the neighbors from above.
  • If a pipe gets wet near a plumbing fixture, then the reason lies in a faulty faucet.
  • If ventilation problems are found, work will need to be done to eliminate blockages blocking the hood.


If condensation appears in the bathroom on the pipes: what to do in such cases? Listing ways to eliminate condensate, one cannot help but recall thermal insulation, which quite effectively helps in this problem.

In case this material is not available, it can be replaced by a simple polyurethane foam. For this, a corrugation with a diameter slightly larger than the diameter of the problem pipe is taken and cut into separate sections that are convenient for installation on communication. After putting on the corrugations, its inner space foams.

How to install thermal insulation on your own

Insulating cold water pipes from condensate is quite easy to do on your own.

This will require the following consumables:

  • sanding paper.
  • Rust converter.
  • Strong thick thread.
  • Fabric strip 50-60 mm wide.
  • Epoxy putty.
  • Acetone.
  • spatula.


  1. Sand the insulated section of the pipeline to improve its adhesive properties.
  2. Pouring a little acetone on a rag, degrease the surface.
  3. Apply phosphoric acid for corrosion protection.
  4. After the pipe is completely dry, an epoxy putty of a thick consistency is applied to its surface (it is important that the material does not drain)
  5. Without waiting for the substance to harden, you need to quickly wind the fabric using good tension. To fix the last turn, a prepared thick thread is used. During this procedure, it is very important that the turns of the fabric completely overlap each other, and the putty completely soaks them.
  6. After waiting until the putty is completely dry, according to the same scheme, you need to apply a couple more layers of thermal insulation. top coat there will be a layer of epoxy material.
  7. When the finish dries, the pipe can be sanded and painted.

Elimination of condensate on the pipeline

To eliminate this unpleasant phenomenon, one of the following methods can be used:

  1. Troubleshooting the ventilation system. Insufficient ventilation can not only lead to condensation on the pipes: it is important to remember that such conditions can provoke the formation of mold, which is very harmful to breathing and can cause many diseases. To enhance passive ventilation, an additional forced-air fan is usually used. manual mode. In addition, automation can be installed, to turn on which a timer or hygrometer is used.
  2. The reason may also lie in large differences temperature regime indoors and plumbing: because of this, surfaces with which cold water comes into direct contact fog up. In the future, the accumulation of moisture can develop into streams flowing to the floor. In this case it helps good thermal insulation cold pipeline, which is easiest to perform using a special tubular material (thermoflex, energy flex, polyethylene foam). This insulation is available in several sizes. When selecting, you need to focus on the indicator of the inner diameter, which should be equal to the diameter of the pipeline. The tube is cut along the entire length, followed by pulling on the pipe and gluing the seam. For these purposes, it is best to use a special metallized adhesive tape of a permanent type.


The indoor microclimate is often directly affected by weather conditions in the form of prolonged rains, or the specifics of the local climate. This is especially true for areas near big rivers, lakes, seas or oceans. In this case, even the most high-quality waterproofing will not help at home: it is much more efficient to use dehumidifiers or air conditioners that have a similar function. It should be said that the struggle to normalize the humidity inside the home is useful not only in terms of combating condensate: it will also have a beneficial effect on the safety interior decoration and health of the inhabitants of the house.

A problem such as condensation on a pipe with cold water is very common, especially in summer when it is hot. It occurs due to the temperature difference on the surface of the pipe and the surrounding air. As a result, small puddles may appear on the floor where the pipes pass. And the reason is not that communications, connections, etc. have been damaged. The reason is normal condensation. How to prevent its occurrence and effectively get rid of it, our article will tell.

The consequences of high humidity

Condensation promotes high humidity environment

The main reason that contributes to condensation is the increased humidity of the environment. That is why this process is typical for toilets and bathrooms, basements, boiler rooms, laundries, etc.

Surfaces damaged by condensation have an ugly appearance. In addition, its appearance carries other dangers. One of them is corrosion, which eventually destroys metal structures. And yet, constant humidity is very fond of mold fungus, which causes allergic and respiratory diseases. Both cannot be called something pleasant and useful.

Causes of condensation

The main reasons for the appearance of a condensation product include:

  1. the presence of a source of high humidity in the room;
  2. inadequate ventilation;
  3. poor thermal insulation of sewerage and water supply pipes.

The occurrence of condensate on cold water pipes for the last reasons is understandable and understandable. But what about sources of high humidity? This reason is for:

  • external weather conditions and climate (continuous rains, sleet, humid climate zone, etc.);
  • geographical features terrain (the presence of large bodies of water nearby, high humidity air in combination with rocky soil);
  • defects in buildings that arose due to violations of construction technology (poor-quality thermal insulation of walls and floors, poor waterproofing of the foundation, lack of hoods and ventilation in the premises);
  • problems arising during the operation of buildings and communications (flooding of the basement, accidents in the water supply system, clogging ventilation ducts, local sources of water vapor in the form of hanging wet linen and vapors of cooking food).

For whatever reason, droplets of water do not appear on your pipe, it must be dealt with.

Methods for dealing with the product of condensation

Ventilation device

A good protective option for pipes is mineral wool.

If your room is experiencing high humidity, you need to take the following steps.

  1. First, remove the source causing it to rise. For example, hang wet laundry outside, on a balcony, or in a room that is well ventilated. Close water containers with airtight lids.
  2. Second, make sure you have good ventilation. It might be simple ventilation window with a grid, which will ensure the removal of excess moisture to the outside.

If you don't know what to do to remove condensation from cold water pipes, try to start with simple passive ventilation. It is done as follows:

  • using a puncher or a crown drill, drill a hole in the wall in the form of a small “window”;
  • paste over it ventilation grill and fix it using construction adhesive or self-tapping screws with dowels.

In the event that such a measure does not bring desired result, you will have to turn to active ventilation. It can be an exhaust fan that will be mounted on the exhaust vent. It has 2 modes - forced and manual. The first is used when the source of high humidity is constantly operating. The second can be used when its action is limited to a certain time. Such fans are sold in hardware stores, and you can install them yourself.

On a note! For convenience, the fan can be equipped with a timer or a humidity sensor that will control its operation time.

Pipe insulation

The inner diameter of the pipe insulation must match the outer diameter of the pipe

And now we will learn how to eliminate cold water condensate on a pipe when its surface temperature differs sharply from the ambient air temperature. Forced ventilation in this case does not always help, and then you have to protect the pipes, resorting to thermal insulation materials.

Currently, their range is quite diverse.

  1. Insulation material is very often sold in the form of mats, which are mineral wool, on one side of which a heat-reflecting metal foil is fixed.
  2. The heater may be in the form of tubes. The value of their inner diameter must match the outer diameter of the pipe to be insulated. Such tubes are made of rubber, polystyrene, polystyrene and other materials.

If you chose the first option, then tightly wrap the entire pipeline with material.

In the case of using a tubular version of the insulation, it should be cut along the entire length, and then put on a pipe that has been wiped dry. It is important to achieve complete tightness of the containment by its tight fit to the riser. If this does not happen, then the water droplets will still moisturize metal structure leading to its destruction. After that, the insulation put on the pipe should be glued along the length of the cut using a special adhesive tape or glue.

Note! If even after the thermal insulation of the pipes, the condensation product does not disappear, then you will have to waterproof the walls and floor. Such overhaul can only be trusted to specialists who know how to work with a heat insulator, waterproofing and facing materials.

If such measures cannot be implemented or they could not solve the problem, then install a dehumidifier or air conditioner in the room that has the function of dehumidifying the air. How to remove condensate from cold water pipes in this case? By regularly draining accumulated water and drying absorbent material.

On a note! The most primitive moisture accumulator is an ordinary bandage, which is wound in the form of a tourniquet around the pipe. Its lower end descends into a jar where water will drain. In this capacity, bags of silica gel are also suitable, which will need to be dried periodically.

The fight against condensate, although painstaking, is not very difficult. We hope everything works out for you! We wish you success!
