Condensation on cold water pipes: what to do, causes of formation, how to get rid of. Ventilation system in a private house

When condensation forms on the cold water pipes, an experienced plumber will always tell you what to do. But there are times when it is not possible to seek professional help, so it is important to know why this phenomenon occurs and how to deal with it.

Reasons for the formation of condensation

Moisture can appear on both metal and plastic surfaces. The reasons for it are equally removable, regardless of So the accumulation of condensate contributes to:

  • poor or no ventilation at all;
  • stagnant water;
  • faulty plumbing;
  • temperature difference;

If condensation is found on the cold water pipes, what to do must be addressed immediately. An unresolved problem causes not only aesthetic ugliness, but also can damage the pipes.

Excess moisture can appear due to sudden changes in temperature and excessive moisture. To eliminate the trouble, it is necessary to establish a ventilation system, and after taking a bath, leave the door open to ventilate the room.

In the toilet, a common cause of pipes "crying" is leaking water in the cistern. The mechanism is simple: the water is constantly renewed and does not have time to warm up to room temperature. This keeps the chimney cold and the room warm. As a result, excess moisture appears.

Consequences of unrepaired condensation

In places where, as a rule, humidity is always high. But if the indicators go beyond the critical mark, then unpleasant consequences are possible for both pipes and living people.

  • Mold and mildew formation. When condensation is constantly present on plastic pipes, water droplets flow down the walls and fall on the floor. As a result, a favorable environment is formed for the development of pathogenic bacteria, which threatens the appearance of mold. In conditions of constant humidity, the fungus begins to multiply intensively and it will be very difficult to get rid of it later.
  • Property damage. Constant contact with water surely spoils all the things in the room. Metal pipes rust quickly, plastic ones lose their consumer properties. Ceramic tiles can eventually fall off, and paint and putty can crack.

To avoid this, you need to know how to remove condensate from cold water pipes and fix the problem in time.

Finding out the cause of the problem

Before fighting for water droplets on pipes, you need to figure out why they appear. To eliminate condensation on the cold water pipes, what to do in such cases is due to the reason for its appearance.

If it is a leak, then at night, when the movement of water stops, you can hear a quiet dripping. Therefore, it is worth finding a place for water flow, eliminating it and the problem with condensation will be solved by itself.

If moisture accumulates on the tank hose and parts of the system close to it, the problem is most likely in the tank system itself. Condensation forms due to the constant presence and relatively warm room. Therefore, it is necessary to establish a drainage system.

When all systems are working properly, the plumbing is in order, it is necessary to check the ventilation. It is enough to put a sheet of paper on the vent and if it falls, immediately clean it. It often happens that this measure alone is sufficient to completely prevent the problem.

In the summer, when it is hot in the room, and cold water is allowed through the pipes, condensation is an indispensable attribute. In this case, the elimination of too sharp temperature differences between the outside air and water in the pipes will help. Moisture-absorbing drugs can come to the rescue.

Problem in piping

When the cause of droplets on the pipes is a malfunction of plumbing or poor ventilation, then it is clear to any layman what to do. But what to do when the source is a technical reason. Often in apartments, pipes for hot and cold water supply are too close to each other. In such conditions, it is clear why condensate on the pipes appears again and again, despite the good exhaust and serviceability of all systems.

If the wiring is in the public domain, you should definitely take care of thermal insulation. But in the case when the network is hidden, you will need the help of a specialist who will solve the layout geometry. In any case, cardinal repairs are required.

Thermal insulation material is used both special and made from scrap materials. Regular corrugation and polyurethane foam will do. In this case, the corrugation is cut to the required size and worn on problem areas. Where unfilled spaces remain, polyurethane foam helps out.

If plastic pipes "cry"

When the question is laid in the house, how to get rid of condensation is solved as follows:

  1. It is advisable to replace the conventional hood with a built-in fan.
  2. Carry out insulation measures using special tubes with an incision. They are easy to purchase at any plumbing or hardware store. These tubes are made of polyethylene, energoflex and effectively protect the tubes. the main condition for their use is careful preparation of the pipes so that they are completely dry.
  3. In the case of a plastic trunk, you can radically solve the problem of "crying" if you treat them with a projector primer. After complete curing, they can be painted with oil paint. This method is suitable if there is an unrecoverable, constant and sharp temperature drop in the room.

Please note that pipes for cold water are allowed to be coated with any enamel, and the hot water supply system is painted only with oil paint.

Getting rid of moisture on metal pipes

The problem with metal systems is no less acute, because excessive moisture threatens the formation of corrosion and complete wear of the pipes. Therefore, if condensation appears on the pipes of cold water, we will describe in detail what to do:

  1. The pipes are cleaned from rust, completely dried and covered with oil paint.
  2. All kinds of cracks in the floor and walls are treated with carbolate, a pasty substance. After it has completely solidified, it is also covered with oil paint.
  3. The entire water main is treated with a projector primer, and then covered with enamel.

It should be remembered that the problem of condensation is often quite difficult to solve, so it is better to prevent it from occurring than to deal with the consequences later.

Experts who are often confronted with crying trumpets have a long history of preventing root problems.

Should be purchased at the Gofroterm plumbing store. The substance is applied to the entire surface of the pipes, as a result of which a strong and elastic base is formed, preventing the accumulation of moisture.

Liquid insulation also has a good effect. It is applied to completely dry pipes and prevents sudden temperature changes that cause condensation.

If there is a large difference between the temperature of the air and the supplied water, it is necessary to insulate the pipes. The most effective and suitable material for these purposes is one that is sold in any hardware store at an affordable price. The material is fixed with a clamp and ordinary wire.

It is possible to eliminate fogging by the proposed methods, but which method to choose must be decided after a precisely established reason.

Wet pipes in a private house

Condensation on pipes in a private house is mainly due to insufficient ventilation. Therefore, if the house is only under construction, you should immediately take care of a strong hood. Before installing the pipeline, you need to insulate it. It is especially worth paying attention to this if the pipes for hot and cold water supply are located in the immediate vicinity.

An inadequate system is a common cause of condensation. Therefore, in order to avoid problems with this factor, it is worth paying attention to this.

For diagnostics, specialists are involved who, if necessary, will carry out cleaning. If the problem is not solved, you will have to install an additional exhaust duct. The ventilation system in a private house often allows you to do this without much damage and high costs.

Thermal insulation of pipes

It is better to insulate all pipes in the house. For these purposes, specialized materials are purchased. But you can use available tools and rid the house of constantly wet pipes.

A regular plastic tube is cut lengthwise and put on the problem area. The space between the pipes is filled with polyurethane foam.

It is easy to secure a metal pipe with an old rag. To do this, we get rid of rust, dry the pipe and wrap it with rags.
