How to repair a pipe leak

So, the place of the leak has been identified and you need to make a decision on how to seal the leak in the heating pipe. In this case, the options to put a rag or substitute a basin are not suitable. Even a minor leak can result in a serious accident. You should also understand that sealing leaks is a temporary measure that only postpones the mandatory overhaul until a convenient time. Agree that stopping heating in winter and replacing a section of a pipe or a connecting unit is not the most pleasant prospect.

Leakage Clamp

A leak found in a pipe can be in any area, primarily at the joints. Most often, you just need to squeeze some knot. Less often - to replace it, which is extremely difficult without the help of a specialist. Cracks in pipe bodies are not as common, but they do happen. Options for how you can eliminate the leakage of heating pipes:

• wind the rubber band over the leak.

Then wrap the rubber tightly with wire. At the same time, you need to control the process, it is better not to crush it than to transfer it. A very large effort can provoke even more damage. If you have metal clamps on hand, which are clamped with a screwdriver, they will simplify the task, since they pull the rubber around the pipe evenly. And there are also factory models of clamps with a rubber insert, the best option, since removing leaks in the heating system is their main purpose, a narrow profile is always better;

• use two-component adhesives such as cold welding.

The name may differ from manufacturer to manufacturer, but all sellers call it that. The principle of its operation is that, individually, the component of cold welding resembles plasticine. After mixing it thoroughly, it will harden in a matter of minutes. After final hardening, you can process it with a grinder. With such plasticine, you need to close up the leak and smooth it out well;

• use an impregnated cloth.

As an impregnation, you can use adhesives that are resistant to high temperature and moisture. Cements are also widely used. To do this, you need to wrap the leak with a material soaked in gypsum mortar. A cement dressing is applied over the plaster cast, the manufacturing method is similar.

If the heating riser leaks, urgently call the master, and before his arrival take measures to eliminate or reduce the leak.

Leak in an apartment building

If a leak occurs on one of the sections of the highway, residents should contact the management company for help. As part of an operative intervention, they can perform several simple actions:

1. Shut off the heating riser. Other residents of an apartment building will be left without heat, but this will help prevent coolant leakage.
2. Cover the damaged area with a blanket to avoid burns.
3. Call emergency services.

Do not try to repair the leak on your own. Report any damage to the heating system to the management company.

How to Repair a Battery Leak

It is not an uncommon situation when it is the heating battery that flows, what should I do in this case? Of course, it depends on the location of the leak. A heating radiator leak appears:

• at the junction of the battery and the general circuit;
• between sections;
• in the case.

Cold welding

To seal the leak in the radiator housing, you need to use a two-component metal adhesive. It may also be suitable to wrap everything with rubber and seal with wire.If a leak has arisen at the section of the threaded connection, then it will be easier to wrap everything with a cloth impregnated with alabaster or cement.

It is best to avoid using sealants. A very common case is when the heating radiator flows at the joints of the sections. What to do is the result of the wear of the gaskets and the repair is limited only to disassembling the radiator and replacing the gasket. Before that, you can try to rewind with rubber or impregnated cloth. It is important that all repair work begins with cutting off the battery from the circuit. In this case, the temperature of the coolant in the radiator should be room temperature.

What is an anti-flood and how does protection against water leaks work?

The anti-flood system consists of several elements: water availability sensors, electrically controlled taps or valves, and a control unit. Sensors for monitoring the presence of water are placed in the places of the most probable leaks. Electric cranes are placed on risers with water, in key places of the water supply and heating systems - in order to minimize the amount of spilled water in the event of an accident. Crane drives and sensors are connected to the control and management unit (controller). It processes signals from sensors and, in the event of an alarm signal, supplies power to the taps. Those are triggered by blocking the flow of water / heat carrier. This is, in a nutshell, how water leakage protection works.

Protection against water leakage consists of three components: water presence sensors, electric taps and a controller that controls all this

These systems are used both for water supply - hot and cold, and for heating. After all, an accident in the heating system is probably even worse than on the water supply - hotter water causes more damage, and can also cause serious burns. In general, for flood protection to be effective, it is necessary to think carefully about the installation locations of sensors and taps.

Leakage reasons

After you managed to stop the leak in the heating pipe, you should think about the reasons for what happened. Since if the cause is not eliminated, breakdowns may occur in the future:

• corrosion.

Merciless to metals. Open heating systems, in which the coolant is in contact with air, especially suffer from it. Together with the flow, it enters the circuit, where it helps the metal to oxidize. It is impossible to cure such a disease, you will have to amputate part of the contour and notice it as new;

• water hammer.

The consequences of a water hammer

Heating and water supply systems are characterized by water hammering. To compensate them, special equipment is installed. The force of the shock wave is such that it can split the edge of a cast iron battery, not to mention weaker points such as threaded, crimped or soldered joints;

• current repair of the heating system.

Before the heating season, the tightness of the system is checked by raising the pressure in them, the so-called hydraulic tests. If in private houses these requirements are almost always neglected, then city networks perform this procedure before and after the heating season;

• mechanical impact.

There are a lot of options: from an unsuccessful blow during installation, to damage when rearranging in a room. The human factor is in charge here.

If a heating boiler leak appears, then there can be no question of any independent repair. In addition, modern devices are quite complex and have many monitoring sensors. If all of them do not give the go-ahead for launch, nothing will happen. In a word, call the master.

Where to install motorized valves

With the installation of cranes, not everything is easy. The specific installation locations depend on the system design. If it is a small apartment with one or two risers - cold and hot water - everything is simple. We overlap the bends and that's it. In more complex systems, it is necessary to think over the place of installation of electric cranes.

The location of the shut-off valves depends on the design of the system

In apartments

If the water supply is centralized, the taps of the system from leaks are placed at the entrance to the apartment / house. It is much better if the taps are located before the meter and filter. But with such an arrangement, operational services may disagree. They usually require the electric crane to be positioned after the meter. In this case, in the event of a leak, the connection between the meter and the filter remains under pressure at all times. It will be impossible to eliminate the leak at these points. You can insist on your own, but you need to prove your point of view.

In some layouts, the apartment may have four risers - two cold and two warm water. In this case, there are two solutions - more correct and more economical. That's right - put two modules, each of which will serve its own zone. This is more convenient, since an accident will happen only on one of the risers / devices and it is unreasonable to disconnect the opposite part. But two modules are double the cost. To save money, you can put one control unit that will shut off the taps by 4 risers. But in this case, do not forget that you will have to pull the wires through the entire apartment.

We need to think about where to install the system elements

In the case of heating, not everything is simple either. Most of the high-rise buildings have vertical wiring. This is when in every (or almost every) room there is a riser and one or two radiators are powered from it. It turns out that at least one crane must be installed for each bend - for the supply. But then the water that is contained in the radiator and pipes will flow out. Of course, this is not so much, but a couple of liters is sometimes enough for the neighbors below to have a stain on the ceiling. On the other hand, it is too expensive to put two taps on each radiator.

In a private house

To prevent the pump from pumping water in an emergency, it is necessary to use a water leakage protection controller with a power relay. If power is applied to the pump through the contacts of this relay, simultaneously with the signal to close the ball valves or valves, the power supply to the pump will be cut off. Why not just turn off the power to the pump? Because in this case, all the water that is in the system can pour out into the resulting gap. And this is usually a lot.

In order to understand in which places of the water supply system of a private house it is necessary to install taps to prevent water leaks, it is necessary to study the diagram. Most often, shut-off valves with electric drives are installed after the pumping station and on the boiler.

Protection against water leakage can be included, or you can assemble your configuration from components

Heating is a little more complicated. It is not necessary to block the movement of the coolant if it is impossible to immediately extinguish the boiler. That is, in systems with solid fuel boilers, water leakage control can be set only if it does not block the circulation of the coolant. If there is a small circuit, taps can be installed so that this small circuit is running and the rest of the system is shut down. If a heat accumulator is installed in the system, taps must be installed so that water does not pour out of it. These are large-volume containers - at least 500 liters, and usually many times more. If all the liquid spills out, it won't seem a little.

In heating systems with automated boilers, taps can shut off the circulation. If the protection against water leaks works and cuts off the circulation, the boiler will stop due to overheating. This is not a completely normal situation, but it is not an emergency either.

Repair of plastic and polypropylene pipes

Most modern sewerage, water supply and heating systems are made from PVC pipes. Water leaks in them do not occur so often and, as a rule, due to mechanical damage or due to improper installation.

If a leak develops in the fitting connection, it is enough to tighten it - this is easy to do even without shutting off the supply. If the reason is a burst pipe, then almost any of the above methods will do for DIY repair.

Taking into account the characteristics of the material, it is possible to eliminate minor water leakage in PVC pipelines using soldering. To do this, gently heat the burst area to a soft state, and also bring a small piece of pipe made of the same material to the melting point. Immediately after that, you need to apply molten plastic to the breakout site. Make sure that the pipe section does not deform due to heating.

In case of serious damage, you can cut the pipeline at the leak and apply polyurethane, epoxy or hot melt adhesive to both ends. Then both pipes should be aligned, after putting a cut plastic bottle on them. Next, a hairdryer is taken and the area to be repaired is warmed up until the homemade "sleeve", squeezing and welded to the water supply, does not form an airtight connection.

Before you repair polypropylene pipes with your own hands using improvised means, think about whether it makes sense to expose your home to the risk of flooding, or is it better to immediately replace the damaged area. If you have a welding machine and experience working with it, this process will take no more time.

Recently, special nozzles for this kind of equipment have appeared on the market, allowing you to reliably seal through holes in polypropylene pipes. How this is done is clearly shown in the video below.

Remember: almost all of the above methods of eliminating water leaks are only a temporary measure. Depending on the condition, it is necessary to replace all pipes or only the damaged section with a new one as soon as possible. In the absence of the appropriate skills and tools, you can always turn to professionals for help.

A flood in an apartment is always easier to prevent than to eliminate its consequences. By installing the Neptune automatic leakage protection system, you will be reliably protected from unforeseen costs for the restoration of your apartment, as well as for compensation for damage to the injured neighbors below,

Heating system diagnostics

The easiest way to detect a leak is in an open pipeline. Wet marks on the floor and walls indicate a leak. When using antifreeze, the stains will be colored. To detect a leak, turn off the riser and inspect all sections of the line. Use a tissue or piece of paper to find damp spots.

It is more difficult to detect damage in the screed and underground. To do this, you need special measuring equipment.

• The thermal imager is designed for diagnostics at a shallow pipeline. It can locate the hot fluid leak. On the monitor, the damaged area will take the form of a bright red blur.
• The moisture meter is suitable for scanning walls and underfloor heating. The leak point is characterized by high humidity, which will be fixed by the device. It is not recommended to use a moisture meter to check underground and street communications, where the moisture level depends on groundwater and atmospheric precipitation.
• A phonendoscope is an acoustic device for diagnosing sounds. Suitable for checking walls and screed for noise sources.

To save time and money, you can order measuring equipment for rent, or contact a specialist.

Search and elimination of coolant leaks

Finding a place where water leaks through puddles on the floor is easy. But if you inadvertently brought the matter to this, then you can consider yourself on the verge of a communal catastrophe of a local nature.

Therefore, you need to pay attention to the details - the appearance of rusty streaks in the places of threaded connections, swelling on the surface of metal-plastic pipes, their loss of shape and strength. If the heating pipes are laid in the thickness of the walls or a "warm floor" system in a concrete screed is arranged on a separate circuit, then leaks can be found only with the help of special devices

A weak (drip) leak can be eliminated without draining the water and without stopping the heating of the house. Elimination of flows of different intensities is possible only on dry and cooled pipes. Therefore, it will be useful to arrange bypass lines (bypasses), dividing the system into several circuits and independent sections using installed ball valves.

Repair of metal pipes and their connections

Even heavily corroded metal pipes have a high residual strength, therefore, during repairs, significant pressing forces can be applied to them and clamps tightened with bolts can be used. For their urgent repair, you may need:

• Heat-resistant (red) silicone sealant;
• Rubber elastic bandage (sold in pharmacies);
• Two-component, metal-filled epoxies (cold welded);
• Bolted metal clamps;
• Thin fiberglass or old women's tights.

In case of a slight leak in the threaded connections, it is enough to unscrew the lock nut (if any) by a quarter of a turn to form a gap of 0.5 mm. Silicone sealant is squeezed into it and evenly distributed over the entire circumference. After 30 seconds, when the sealant begins to polymerize, the nut is tightened.

If there is no lock nut, then it is necessary to clean the joint from old paint, scale, rust and degrease it. In case of a weak leak, you need to break a piece of "cold welding", as described in the instructions for it, and evenly distribute it over the entire circumference of the joint, especially carefully smearing the edges of the joints. For a higher flow, you can apply silicone sealant or a two-component metal-filled compound to the joint and press it down with a tape of fiberglass or a piece of women's tights.

A crack or fistula in the pipe can be wrapped with a rubber elastic bandage, overlapping with each subsequent turn half of the previous one. The length of the winding should be twice as long as the damaged section. It is necessary to make 2-3 layers of winding and secure it with clamps. A good result is obtained by winding with a hemostatic tourniquet from a car first-aid kit, which can be secured with a standard latch. A crack in a pipe can also be repaired with an epoxy compound in combination with a reinforcing material - elastane or fiberglass. But at the same time, you will have to clean up to metal and degrease the entire area on which the bandage will be applied.
