Many are interested in how to eliminate condensate on the pipe cold water. Because this problem is encountered very often.
At first glance, damp pipes for supplying cold water are a source of dampness in a kitchen or bathroom. Also, this phenomenon can provoke the appearance of mold.
These factors will shorten the period between system repairs in a wet room. Why condensation occurs, and how to resist it, will be discussed further.
Most often, condensate from a cold water pipe appears due to insufficient ventilation in the room. It is for these reasons that moisture is collected in droplets in a system that transports cold water.
Moist air helps a lot. For these reasons, before installing pipes for cold water, it is recommended to create a thermal insulation layer that will prevent any temperature difference on the top of the pipe.
This problem also occurs when the nozzles for cold and hot water.
With such a problem in the bathroom or bathroom, it is recommended at the very beginning to check the functioning of the ventilation.
Behind long time she could get upset. Malfunctions in the ventilation network are clearly visible when closed windows if there are plastic windows in the room. This can be checked very easily.
ADVICE! If you take a paper sheet and attach it to the hood with closed plastic windows, and then do the same with open windows, then the difference will be visually noticeable. If there is no ventilation, then it will be visible immediately.
And one more feature in the bathroom is the piping layout with cold and hot water. They are often carried out in close proximity, without laying thermal insulation.
It is not surprising that in the place where water is supplied to the plumbing, the pipes begin to “cry”. On open wiring condensate is easier to remove.
But, in a situation where the network is hidden in the wall, the solution of the issue entails more complex work. This will include repair measures, because the fastest way is to change the geometry of the structure.
Considering the reasons for the condensate of a water pipe with cold water in a bathroom or bathroom, it should be noted that in general the situation is similar to the one described above, but one “BUT” arises.
In these rooms, there are an order of magnitude more pipes, and the space, as a rule, is smaller. And here, even at the installation stage, it is necessary to solve the issue of thermal insulation of pipes.
How to solve this problem
And she deserves special attention. You can purchase special material that can be easily purchased at any hardware store for little money.
It does not matter if this was not at hand, you can use improvised means. Mounting foam and corrugation can save the situation.
The volume of the corrugation should slightly exceed the volume of pipe products laid in the network. The process itself is deceptively simple.
The corrugation is pre-cut into the necessary pieces, and they are put on the nozzles. The empty space is filled with mounting foam. At this point, the mission is considered completed.

There is another very simple method that will help eliminate the appearance of water drops on the pipes. For work you need to prepare:
- sanding paper;
- phosphoric acid;
- thick thread;
- strips of old fabric;
- putty knife;
- acetone.
Course of action:
- Any pieces of unnecessary fabric are cut into strips no more than 7 cm wide, which are rolled up. They are recommended to be prepared with a margin so as not to be distracted during work.
- The pipe is plastered, otherwise the material will not firmly adhere to it. Then it is degreased with acetone.
- At this stage, a rust converter is applied, and when the pipes dry, putty is applied to them. This material instantly hardens, for this reason, you will have to act quickly.
- The prepared pipes are wrapped with fabric strips, so that each subsequent turn overlaps the previous one. The final coup is tightly tied with a cord.
- Thus, insulation from fabric strips is applied in several layers.
- The procedure is completed by applying an epoxy layer. When it dries completely, the pipe products are sanded and the paint of the selected shade is applied.
How to get rid of condensation on plastic pipes
Leaks in plumbing fixtures are a common basis for the appearance of condensate. If the workpiece that supplies water to the sanitary fixtures gets wet, then breakdowns may be in the tap, in shower mixer, in the inlet valve of the toilet tank. A wet riser may indicate that there are leaks in neighboring apartments from above.
If the pipe network is laid out of plastic, then the problem of how to eliminate condensate on plastic pipes is solved as follows:
- The hoods are checked and the ventilation grille is replaced with a compact fan.
- The network is isolated with special tubes with a cut. These products are offered in every hardware store. They are made from energy flex and polyethylene foam. This is a very simple method, only before starting the insulation, it is necessary to dry the pipes thoroughly.
- Full insulation of plastic pipes can be provided by the use of fabric strips and plastering. Above is detailed description how it is done.
Features of a metal water pipeline

The problem of how to eliminate condensate on metal water pipes is no less acute than in previous situations.
If plumbing metal pipelines are constantly exposed to drops of water, they will quickly be damaged by corrosion.
The following actions help to eliminate the condensate of metal pipes:
- Branch pipes are protected from rust, dried and opened with drying oil, oil paint.
- Cover with carbolate. This is a paste-like agent for sealing cracks in the walls and floor, it is applied with a layer of 0.5 cm. This composition should harden for a day, and then the surface is sanded with fine sandpaper and painted with oil paint.
- Projector primers. They consist of zinc dust, which is diluted with drying oil. With this composition, the highway is opened, and then it is painted (enamel).
- The line in the toilet can be treated with a product based on drying oil and minium, or with special primers (for example: FL-031, FL-053).
Advice! In the bathroom, the cold water main is allowed to be painted with any kind of enamel, and water pipes for hot water supply it is possible to cover only with oil resistant enamels.
How else do you deal with condensation?

Eliminating condensation on pipes is not an easy task, without determining the exact cause of this phenomenon.
Experts on this subject express such an opinion.
- Professional plumbers are advised to purchase Gofroterm. This is a special composition that can be bought at building materials stores. It is superimposed on the surface of the pipes, and forms a strong and elastic film there, which prevents wet manifestations.
- Also, experts are confident in the effectiveness liquid thermal insulation, which is applied to a dry and cleaned highway.
- If all plumbing and piping is in good condition, then condensate may accumulate due to the temperature difference between the pipes and the air. In this situation, only the insulation of the system will help. by the most suitable option for such insulation, professionals call foamed polyethylene or merylon, which are not difficult to buy at any building materials store for a low cost. This insulating material is fastened by putting it on the pipeline. Fix it with a clamp and wire.

IMPORTANT! Experts warn that it is possible to eliminate the fogging of the cold water supply different methods. Which of them to choose, can be decided only after a thorough analysis of the situation.
The fact is that in addition to the main ones, there are side effects that lead to the formation of condensate. The source of dampness is evaporation from the basement, poor waterproofing and wall insulation.
Because of this, condensation and frost appear. In such situations, there is only one way out - this is the insulation of the floor and walls in the house with high-quality material.
In addition to the reasons already listed, leading to "wet" troubles, there are others. For example, weather conditions. Frequent and prolonged rains, close location of the reservoir, proximity ground water also significantly increases the moisture index in the house.
You can reduce it by installing a moisture absorber or an air conditioner that has the function of dehumidifying the air. Dehumidifiers on the market today are an excellent method for removing moisture.

These are plastic boxes containing absorbent tablets. When using these devices, they not only get rid of fogging on pipes, but also eliminate moisture throughout the house.
Experts can advise how to eliminate condensate on a cold water pipe. If they are entrusted with this task, then you can be sure that they will quickly and effectively eliminate the causes leading to dampness in the apartment. And in this case, it will be possible not to worry about the health of people.
While I lived in the South, and even on the top floor, I did not know about such a problem as sweating cold water pipes. But now, after moving, I faced this problem.
It turns out that a sweating cold water pipe can produce a puddle with a total volume of up to 5-7 liters of water per day. This is not at all pleasant and unnecessary. What to do?! Let's figure it out!
Pipes sweat, what to do. The answer is simple
Indeed, the answer is simple, but the solution must be complex and may have several options. Let's decide on the reasons why the pipes sweat, and then we'll talk about the methods and materials that can be eliminated this problem. By the way, pay attention, perhaps from old age, micro-holes appeared in the pipes through which water oozes. but if there are no leaks, then read on.
Why do cold water pipes sweat?
The answer to this question lies in the physics textbook for grade 7, it seems. Condensation on the pipes appears as a result big difference temperature between the cold water pipe and the air temperature. Thus moisture from the air condenses on the colder surface of the water. The more moisture in the air and the colder pipe the more condensation will occur.
Of course, if the water in the pipe does not move (that is, no one consumes it in the whole house), then the temperature of the pipe will approach room temperature and the amount of condensate may be reduced to zero. But in the house all the time there is an analysis of water, so the pipe is cold all the time.
That is, there are two reasons: air humidity and low temperature of the cold water supply pipe.
Now we figured out why the cold water pipe is sweating and we will fight this ailment.
To prevent cold water pipes from sweating
- It is necessary to insulate pipes as much as possible
- Find water leaks from neighbors (a plumber from the management company will help you with this)
- Improve indoor ventilation
The most important and simple event is the thermal insulation of the pipe. How to insulate our cold water pipe? Firstly, I’ll immediately make a reservation that it doesn’t matter what material - metal, carbon fiber, polypropylene, metal-plastic, gold, silver .., your pipes are made, without thermal insulation they will sweat!
Thermal insulation of cold water pipes
The easiest option is to wrap heat-insulating material:
- Thermal insulation flex
- K-Flex ST
- Thermal insulation for polyethylene foam pipes
- Thermal insulation cylinder
- Thermal insulation "Energoflex"
You can continue this list for a long time, but the point is to wrap the pipe with heat-insulating material from floor to ceiling or from beginning to end in several layers. The minimum thickness of the thermal insulation layer should ultimately be at least 3 centimeters, and preferably five.
It is very important that the thermal insulation fits snugly against the pipe and is securely wrapped with tape. In places where aesthetics are needed, you can wrap it with tape with metal foil.
The disadvantage of this method is that it is difficult to tightly and completely wrap the pipe around bends, as well as on shutoff valves! Also, it is not always possible to make such a focus in hard-to-reach places.
Warming paint (heat-insulating) for pipes, so as not to "sweat"
In this case, you can use a more expensive, but convenient way.
There are paints for thermal insulation of surfaces and pipes as well. To insulate a cold water pipe, it is necessary to wipe it from moisture and apply 4-5 layers of heat-insulating paint on the pipe. Each layer must dry, after which the condensate on the pipe is wiped again and the next layer is applied.
The third method can be combined, that is, first paint the pipes heat-insulating paint, and then dress in a foamed heat insulator.
As I already said, sweat and metal pipes and plastic (polypropylene, metal-plastic), therefore, all types of pipes must be covered.
But! Before applying thermal insulation to the pipe, it is necessary to carefully check whether there is a micro-hole somewhere in the pipe, from which water oozes drop by drop. Especially often such a trick lies in metal pipes. If condensation forms over the years, then the metal pipe rots at an amazing rate, resulting in micro-holes and micro-leaks. So be careful not to have to redo it later! Most often, such micro-holes form in places near the floor or ceiling (in these places the most favorable conditions for corrosion of metal pipes).
After right activities on the thermal insulation of pipes with condensate, you can say goodbye. And if they did it wrong or there is a leak in the pipe, then there will be less condensate, but it will not disappear.
My advice to everyone, do not skimp on thermal insulation. It’s better to get confused once than to suffer every day from dampness (which is unhealthy), mold, smells and just constant puddles ..
Why does condensation appear on cold water pipes, what to do in this case? Condensation is a common problem, and it can appear on both metal and plastic pipelines. At first glance, the problem is insignificant, but over time it causes a lot of trouble in the form of rust, mold and bad smell. That is, you still need to get rid of the condensate. To do this, you need to find out the reasons for its occurrence. Why do pipes sweat?
Why does condensation appear on cold water pipes
Most often, you can observe condensation on the pipes in the toilet. One of the reasons is a water leak in the tank. The water is constantly changing and does not have time to warm up, hence the humidity. We get rid of the leak in the tank - this reason will disappear.
Sometimes puddles appear at the riser from excessive moisture. This means that the neighbors living above have a leak in the tank. At night, listen to the murmur of water in the sewer, and you will immediately understand everything.
Condensation also forms due to high humidity and temperature fluctuations. To avoid condensation, you need good ventilation. To get started, just leave the toilet door open overnight, you may find a dry pipe in the morning.
The reason is obvious - the ventilation duct is clogged. Unscrew the grate ventilation duct and clean everything very well. A draft should appear in the ventilation duct.
In the event that there is ventilation, but it does not cope with the problem, you can install exhaust fan. It attaches in place of the ventilation grille and you turn it on as needed.
The choice of fans in modern building supermarkets is huge, for every taste and at any price. IN Lately installation of such fans in toilets and bathrooms is very common.
How to fix the problem of condensation
How to get rid of condensation on the pipes in the bathroom? The pipes in the bathroom are also sweating. The reason may be the same. Condensation on the riser - neighbors have problems with plumbing. The pipeline that supplies water to your plumbing gets wet - the faucet does not work well. The lack of a hood, as in the first case, exacerbates the problem.
If hot and cold water systems are very close to each other, fogging cannot be avoided.
It is necessary to make thermal insulation of pipes, this is an excellent protection that will allow you to remove condensate.
Often, condensation forms on the pipes in the bathroom due to a malfunction of the faucet. Leakage of water contributes to their cooling. There is only one way out - repair of the crane!
How to get rid of condensation? Completely get rid of fogging of pipes will allow insulation for pipes. It is necessary to isolate cold water pipes from interaction with the external environment. There are special thermal insulation materials, using which you will rid the pipes of condensate. You just need to buy such material and insulate the pipelines. The abundance of such materials in the construction materials market is very large.
In case you prefer a budget option to eliminate moisture on the pipes, and do not plan to purchase expensive thermal insulation material, you can use other ways. Need to buy a bottle polyurethane foam And plastic pipe or corrugation, the diameter of which exceeds the diameter of the condensate pipe. The corrugation or pipe is cut into pieces so that you can put them on the problem pipe, then put them on and fill the voids with mounting foam.
There is another budget option for getting rid of condensate. You will need sandpaper to remove rust and acetone, so that after that it is good to degrease the problem surface. The best way to process the pipeline phosphoric acid and then apply a layer of epoxy putty on it so that it does not drain.
Then immediately wrap the pipeline with previously prepared strips of fabric so that the material is saturated with putty. You can use an old sheet by cutting it into pieces that look like bandages. Putty with fabric will quickly harden.
You can do this several times in the same way. The work ends with the application of finishing putty. It will look aesthetically pleasing if the putty is sanded and coated water-based paint the color you want.
In most cases, thermal insulation of pipes solves the problem of condensate, but sometimes the level of humidity in a house or apartment is so high that waterproofing of the floor and walls is necessary.
In fact, condensation is considered to be the result of the accumulation of excess moisture on any surfaces that have a temperature lower than that of the surrounding air. Basically, condensate appears on pipes and containers in which cold water flows, or it appears in rooms in which there is a source of high humidity. Such premises include: a toilet, a boiler room, basements, laundries and bathrooms.
In addition to the aesthetic appearance, condensate on pipes can be quite dangerous consequences so it's best to get rid of it.
Why is condensation on pipes dangerous?
Condensation on water pipes is not only not beautiful, but also dangerous. I explain why it is better to get rid of condensate on pipes. If you have metal pipes, then corrosion can appear from condensate, which leads to destruction. And for people, this will be reflected in the source of the respiratory and allergic disease. All this will happen due to the fact that mold will begin to appear on the pipes. Mold is a type of fungus that is quite harmful to humans. It can cause serious illness in people. I would especially like to mention bronchial asthma and a noticeable decrease in immunity. In my opinion, I have given sufficient arguments to convince you to get rid of the condensate on the pipes. And to put it in everyday language, to make sure that the pipes do not sweat.
Why do pipes sweat?
Consider the causes of condensation on pipes. The main reasons include the following:
- poor ventilation
- low level of thermal insulation of sewerage and water supply pipes,
- the premises have high level humidity.
Here it can be noted that the sources with a high level of humidity include the following reasons:
- terrain features,
- defects in the operation of technological communications,
- building defects,
- external weather conditions, climate.
How to get rid of condensation?
Now let's look at how to get rid of the condensate that appears on the pipes.
- If there is a high level of humidity in the room, then first of all you need to eliminate the occurrence of high humidity. For example, it's best to hang wet laundry in another ventilated area, or you can use airtight lids to seal water containers.
- The next step, how to get rid of condensate on the pipes, is to provide ventilation. In this case, you can set ventilation window with a grid that will help to display excess moisture outside your premises. In order to make such ventilation, you will need to drill a hole with a puncher and a drill in the form of a crown. Then insert the ventilation grille and fix it using self-tapping screws or construction adhesive.
- If all this is not enough to correct the situation in the room and get rid of condensate on the pipes, then you will need to do active ventilation.
Active ventilation looks like an exhaust fan that can be mounted on an exhaust vent, and it works in two modes, namely manual and forced. The forced option is considered more preferable, and the manual mode is used for limited temporary actions. In manual mode, you will need to attach a timer, or a special humidity sensor, which will help drive the fan into action. Forced ventilation will be inappropriate if your room has a high level of humidity.
- If the humidity in the room is very high, your best bet is to insulate the pipes with special thermal insulation materials to get rid of condensation on the pipes. All heat-insulating materials are made in the form of mats, which consist of metal heat-reflecting foil and mineral wool. They can also be made in the form of pipes, in which the inner diameter will match the outer diameter of the pipe. Such thermal insulation materials are made from different material, and they take not only rubber, but also various polystyrenes, foam plastics. Such material must be carefully wrapped around the pipes and fixed.
If you are taking heat-insulating tubular material, then you will need to cut it along the entire length. After that, you will need to wipe the pipe dry, and put heat-insulating material on it, so that it is completely tight. If you make a mistake, then you won’t be able to get rid of the condensate on the pipes, it will begin to appear again, and the work will be done for nothing.
Most often, the formation of condensate on pipes with cold water is associated with poor ventilation in the room. Condensation on the pipes appears as a result of a large temperature difference between the cold water pipe and the air temperature. 2014 All about plumbing and pipes. © All rights reserved. For example, like this paint from condensate on pipes.
Warm, humid room air surrounds the surface of the pipe, which is at a much lower temperature, resulting in condensation. You can apply liquid insulation "Korund", which is applied to the surface of the pipe in the same way as ordinary paint, using an ordinary paint brush. The only thing to remember: before using any insulation, a pipe that sweats must be dried.
It looks like a thick-walled pipe with a longitudinal section. This insulation is put on a pipe with cold water. Due to this, a sharp temperature drop disappears, and condensation does not form. In short, you need to make a thermos for the pipe. Yes, and do not forget to dry the pipe before insulating it.
Leave the toilet door open at night, and if there is no condensation in the morning, then the problem is precisely in high humidity with a lack of ventilation. Well, if you do it “as for yourself”, then you will have to insulate the pipe to prevent condensation.
Why is the cold water pipe sweating?
Each issue contains a link to a FREE download of one of the books in the "Bonus" section. While I lived in the South, and even on the top floor, I did not know about such a problem as sweating cold water pipes. But now, after moving, I faced this problem. Let's determine the reasons why the pipes sweat, and then we'll talk about the methods and materials that can fix this problem.
You can continue this list for a long time, but the point is to wrap the pipe with heat-insulating material from floor to ceiling or from beginning to end in several layers. It is very important that the thermal insulation fits snugly against the pipe and is securely wrapped with tape.
"Fogging" pipes in the bathroom
The disadvantage of this method is that it is difficult to tightly and completely wrap the pipe around bends, as well as on shut-off valves! The third method can be combined, that is, first paint the pipes with heat-insulating paint, and then put them in a foamed heat insulator.
After the right measures for thermal insulation of pipes with condensate, you can say goodbye. And if they did it wrong or there is a leak in the pipe, then there will be less condensate, but it will not disappear. There are actually not so many reasons that cause moisture to settle on the surface of the pipe, but each of them has several variations, which greatly complicates the process of finding the root cause.
Dealing with condensation on pipes in the toilet
It is a foamed polyethylene in the form of long and hollow covers inside. The formation of tiny water droplets on pipes, both in apartments and in private housing, is a common occurrence.
Excess moisture on the pipes causes an unpleasant smell and dampness in kitchens, toilets and bathrooms, which contributes to the development of fungus and mold. Most often, the appearance of moisture on the pipes is caused by the temperature difference between the surface of the pipes and the room.
Condensation: why pipes get wet
Due to humid air, sewer risers and pipes that conduct cold liquid tend to have drip evaporation. The answer to the question of why condensate drizzle forms on bathroom pipes lies in the same reasons as on toilet pipes. by the most simple method to eliminate condensation is a simple coating of the pipe with special heat-insulating materials (paint) purchased at hardware stores.
How to remove condensate from pipes
These pipes are available in various sizes. Before using it, wipe the surface of the pipe from condensate. If it is impossible to purchase an insulating pipe, it is allowed to use mounting foam, which is the best remedy in the fight against condensation.
Heat-insulating paint for pipes
It is necessary to monitor the thermal state of the pipes: they must be warm, not cold. His unpopularity is due to corruption appearance pipes and the entire bathroom. An important reason for the occurrence of moisture in pipes is the presence of cold floors, poor foundations, uninsulated walls and basement fumes. Condensation on the pipes can cause mold development, as well as a reduction in the time interval between repair work in wet areas.
That is why on sewer riser or pipes supplying cold water, drip moisture forms: moist air fully contributes to this process. If this was the reason, then a thrust should appear, the presence of which can be checked with a lit match. Another point is the features of the distribution of cold and hot water in the bathroom.
It is not surprising that in the place where water is supplied to the plumbing equipment (simply - a mixer), a pipe with cold water “cries”. If it goes in the wall - the decision suggests itself and is associated with more complex work, including repairs. Often the cause of condensation on the pipes in the bathroom is a malfunction of the faucet. The situation is similar to that described above, with only one “but” - there are much more pipes in the toilet, and they are all laid in a small space.
Now you know what to do if condensation forms on the pipes in your apartment! Condensation accumulates on the pipes from the temperature difference. The pipe cools even more and becomes covered with condensate droplets. The simplest and effective method to combat condensate on cold water pipes, is their rag winding.
