How to eliminate the leak in the heating system at home? How to eliminate the leak of the radiator with your own hands?

Heating the house can fail at the most inopportune time. This problem gives a lot of trouble, but it needs to be solved as quickly as possible. Depending on the type of malfunction, there are different ways how to eliminate the leak in the house heating system.

What are the types of leaks

1. Infringement of tightness in places of joints.
2. Slot in the radiator.
3. End-to-end corrosion or crack in pipelines.
4. Deformation in cavities from freezing or overheating.
5. Cracks in the equipment.

There are general rules on how to eliminate the leak in the house heating system:

• Turn off the site with a malfunction and drain the water;
• Clean, dry and degrease the place with a defect.

Leak in the joints

Repair in the place of connection is simple: it is untwisted, the thread is cleaned and a seal is applied to it, impregnated with paint, linseed oil or sealant, and then again wrapped.

How to eliminate leakage in a heating pipe. Cause. What to do?

Cracks in the pipes appear as a result of mechanical damage or from corrosion.

A rusted metal wall is difficult to weld because it is thinned from corrosion.

There are different ways to eliminate the leakage of heating pipes. The leakage of the heating pipe during temporary repairs is eliminated with the help of a "doll" - winding with burlap or bandage with impregnation with liquid glass, silicone sealant or waterproof glue.

When there is no way to dry the pipe, the "doll" is made on a damp surface with a special sealant. The method is used only for weak leaks.

Also apply "cold welding", which is applied to a dry surface. The place of repair can be dried with a hairdryer. It takes time to solidify the composition, since epoxy glue is used as the base.

Correct the electric welding can be a crack, resulting from mechanical deformation or as a result of freezing of the coolant. In case of corrosion damage, the site is cut out and a piece of a new pipe is welded. You can cut a new thread and screw the union. The old pipe is changed entirely.

Long proven method is a rubber pad with a yoke. Although this is considered a temporary measure, but in this way it is possible to eliminate significant leaks for years. Even special tube clamps are available, which can be purchased in many sanitary ware shops.

Elimination of leaks in radiators

How to eliminate the leak of the radiator with your own hands? In modern heating systems, each valve is equipped with valves that overlap before replacing it.

Old heating appliances should be replaced with new ones. Modern products have greater thermal conductivity and their cost will pay off by saving energy costs.

How to eliminate the leakage of the radiator ? What to do? First you need to determine the place of leakage. Most often these are places of connection with the pipeline or at the joints of sections.

If the leak is not visually detected, the radiator is immersed in a container of water. The air will begin to escape through the hole. A small leak can be eliminated as follows.

1. Remove the old gasket and paint. Splice the wire to the metal. Degrease the area with benzene or thinner.
2. Take putty, which can serve as a mixture of epoxy resin with metal powder, polymer sealant, cold welding. The composition should be applied to the ribbon from the fabric, after which to produce a dense winding in 2-3 layers on the joint.
3. Put a yoke on the putty and tighten it with bolts and nuts.
4. After solidifying the adhesive composition, install the radiator in place and fill the system with water. At the top of each heater there is an air bleed valve, which is removed when the system is running.

After the heating season is over, the radiator or its damaged sections change to new ones. Sometimes it is enough to replace the gaskets between the sections.

Leakages are also eliminated by dissolving the sealant in the coolant, which solidifies in place of the leak, creating a seal. Cracks in steel radiators are eliminated by electric welding.

Many of the above methods are temporary. At the first opportunity, replace the defective heater.

Features of polymer pipes

Insufficiently knowledgeable user can buy pipes intended for cold water mains. Leakage may occur from temperature deformation. Therefore, you should buy pipes in specialized stores, where you can get advice from a qualified manager.

Features of the repair of the warm floor

How to eliminate leakage in the heating system at home, if there is a "warm floor"? Connections of plastic pipes may eventually leak. When installing a warm floor, you should always make connections in accessible locations. If the place is further hidden, for example, in the wall, then the pipes must be connected by thermal welding.

Together with the "warm floor" can be additionally installed radiators. How to eliminate leakage in the heating battery with your hands in this case? Its repair is carried out in the most usual way. To do this, there is a source of leakage, which is then eliminated by applying a patch impregnated with a sealant or special glue. Before that, the surface of the metal must be properly prepared.

The heat carrier passes through the entire system, so with small leakages, a special water-soluble sealant can be used. In a complex system of heating the floor and rooms, it will fall into all the cracks and securely seal the leaking joints. The method is effective in the loss of coolant not more than 5-7 liters per day. But first we must try to find a malfunction and eliminate it directly on the spot.

Modern sealants can have new properties. They add lubricants and anticorrosive substances, which makes it possible to increase the durability of the heating equipment.

The disadvantage of the sealant in the underfloor heating system is the possibility of plugging gaps in thermostats. If they are constantly regulated, then there will be no blockages. In the extreme case, the coolant containing the sealant is drained after a short time after elimination of leaks and replaced with a new one.

Prevention

A mandatory measure to prevent and check leaks is flushing the system once a year and conducting its hydraulic pressure tests. This allows you to detect and eliminate weak points where cracks or gaps begin to appear.

To protect against corrosion, radiators and metal pipes are painted from the outside. Water should not be drained from the system. It is only necessary to relieve the excess pressure for the summer period.

Conclusion

Timely detection and elimination of leaks in the communications of the house allows you to save property damage and save equipment. Availability of necessary materials, knowledge and skills, how to eliminate leakage in the house heating system, are necessary for prompt intervention when a problem arises.

Replacement and repair of heaters are made in more favorable conditions, when they do not work. Simple ways to eliminate leaks are effective, but a temporary measure. It is advisable to carry out basic repairs after the heating period is over.
