How to drain water from a storage water heater: 3 simple ways

When operating a storage water heater, the owner cannot do without complete drain of water from the tank. At the dacha will have to do this at the end of the season to prevent freezing of fluid in winter. In the apartment, drainage of water from the storage tank is made less often. once in 1-3 years, when the device is required to be cleaned from Nakipi. The whole process will take no more than one hour. A person who has encountered the problem for the first time should know how to drain the water from the water heater correctly, so as not to damage the device.

So that a person does not doubt whether it is necessary to drain the water from the tank or you can do without this procedure, you need to clearly decide on the problem that has arisen. Many manufacturers of water heaters do not recommend leaving the device without water for a long time due to the danger of corrosion of metal parts.

Mandatory need to drain water arises in three cases:

  • Mandatory water drain is required by the water heater installed in the country. The question of how to do this arises from the owner at the end of the season. If water does not drain the water for the winter, then at a negative temperature, the liquid freezes and break the accumulative capacity of the water heater. The problem does not apply to the owners living year.round in a summer house.
  • The need to drain the water occurs when the water heater is damaged, as well as the preventive cleaning of the container from the scale and dirt. The frequency of planned maintenance depends on the design of the device, as well as the quality of the liquid. The greater the stiffness of the water, the faster the scale forms. However, on dry heats, solid accumulations are delayed longer than this occurs in devices with open heating elements.
  • You can’t do without drain in the apartment during the water supply accident. From the funded container designed for 80 or 100 liters, you can take a liquid for technical needs: washing the toilet, washing hands and other targets.

If, according to the instructions, the device is not designed for a long simple without water, then during the water supply accident you can try to find another solution to the problem. As an option, purchased water in bottles will help out.

It is not necessary to devastate the accumulative tank in the country during the departure of the owners. Although, here it is worth taking into account the duration of the absence, the design features of the water heater, the minimum temperature indoors and the source of the water intake. And now about everything in order:

  • If a prolonged departure from the cottage falls for the winter, then with severe frosts, the temperature inside the room will drop to a negative mark. No matter how the lack of water is destructive for the device, the liquid must be drained.
  • Inside the room where the air temperature does not drop below 0 O C, the stainless tank is better not to empty. In the presence of water, the process of corrosion is less.
  • Devices with copper heaters with simple it is better to devastate. Here the corrosion process occurs in the opposite direction. Copper in water with increased rigidity is destroyed faster.
  • A long simple water heater is dangerous. Stagnant water begins to rot, which can be found out by unpleasant odor. This happens faster when the water heater is fed from the home well.
  • Chlorinating is performed in a centralized water supply, due to which putrefactive bacteria are destroyed. If you leave the boiler not drained for a week, then the probability of decay of water is minimal.

In general, with short.term departures from the cottage, it is not necessary to devastate the capacity of the water heater. Stagnant water can simply be drained, and the recruited fresh liquid is warmed a couple of times to the maximum temperature.

Ways to drain water

To completely drain the water from the water heater, it is not enough just to open the drain valve. With this action, only a couple of liters of liquid will come down. The rest of the water will hang inside the tank. For complete devastation, it is required to get air into the accumulative capacity. How to do this correctly, you can find out by reading the instructions of the boiler manufacturer. In general terms, the drain procedure can be performed in three ways.

Proper drain of water through the safety valve

So that in the future it is easily possible to drain water from the boiler, you need to initially correctly install the device. How to do this, we will now consider.

Firstly, necessarily mount a safety valve on the cold water entrance pipe. This part has a drain control lever to verify performance. The case is equipped with a nose, to which a hose is connected, which allows water to the sewer. Secondly, if the design of the device does not provide a technical hole with a stopper for starting the air inside the tank, then an additional crane is placed on the hot liquid output pipe.

Let’s look at how to drain water through the valve from the boiler:

  • Initially, the boiler is under pressure. First, they close the locking reinforcement of the input of cold water, and then try to the maximum to lower the water from the water heater through the faucet crane.
  • When the water from the mixer stops flowing, the tap is closed. On the safety valve turn the lever. The drain will begin as soon as the air enters the tank. If the device has a special cork, it is opened. In the absence of a technical opening, an additional drain crane is opened on the hot water pipe.
  • With air entering the container, the water merges through the supply of the safety valve.

The drain of water from the boiler through the valve is carried out slowly, but labor costs are minimal. 80 liter tank will become empty after about two hours. If the safety valve is overwhelmed, the drain time will drag out to 3-4 hours.

Quick adjustable drain through the cold water supply pipe

When the question arises of how to quickly drain the water from the storage water heater, you can use the second more complex way. They begin work by giving pressure, how they did it in the first way. After the water from the mixer stops flowing, the tap is closed.

The further procedure, how to drain water from the storage water heater provides for the following actions:

  • On the pipe of the HVS boiler, the crane was closed before tearing pressure. Now they close the crane on the GVS pipe. The fluid inside the container freezes from the reinforcement overlap.
  • A container of the size of the accumulative tank is substituted under the boiler. The taping key is unscrewed by the CVS crane from the safety valve. The plastic pipe will easily bend to the side.
  • Next, the key is unscrewed from the boiler pipe safety valve. The fluid.hovering inside the container will slightly begin to flow or drip. Now it’s time to open an additional drain valve on the DHW pipe or a factory air cork if it is provided.

The remains of the hung water pour from the pipe of the CVS connection. The capacity of the capacity is 80–100 l for approximately 3-5 minutes. The fluid movement intensity can be adjusted if necessary.

This method is clearly shown in this

Quick unregulated drain through a cold water pipe

The third method is suitable for those who want to quickly lower the water from the boiler if there is no drain valve on the hydraulic pump pipe or a cork for supplying air inside the tank. It should be noted that the drain rate should not be stopped and adjusted. In order not to flood the room under the water heater, set a large container.

After tearing pressure, as was done in the first and second method, the DHW crane on the boiler pipe is blocked. The tap tap is already closed. The tap tap is unscrewed from the tap pipe with a tap pipe. The fluid.freezing inside the tank does not flow. Next, unscrew the tap with a pipe from the GVS pipe. As soon as the air penetrates the air, the water rushes sharply from the pipe of connecting the CHS crane. The drain will stop when the tank is completely empty.

Features of water drain from boilers “Ariston”, “Termex” and “Electrolux”

The basic principle of draining water from all accumulative boilers is the same. Some actions may vary depending on the design features of devices of different manufacturers. Consider how the drain occurs in three popular models:

  • The drain of fluid from the water heater “Termyx” is best carried out through the pipe. How to do this is considered in the second method. First, the tap is twisted from the CVS pipe, and the hose is wound in its place and led to the sewer. For vertical models for supplying air inside the tank, shut.off valves are twisted from the DHC pipe or an additional drain valve is opened if it is provided for installation. Horizontal models have a special air traffic jam. During the drain, the plug is opened.
  • Ariston boilers merge exactly like the vertical Termies. The difference is the Eureka model. After dismantling the cranes from the HVS and the DIS pipes, the built.in mixer is removed. Under the cladding, the air supply plug is hidden. It needs to be found and unscrewed, after which the drain will begin.
  • Water from Electrolux boilers is drained according to all the rules through the nose of the safety valve. How to do this displays the first method of drain.

Each manufacturer describes the features of the drain of water in the instructions. She should familiarize yourself with her before starting work.

upper, connection, boiler, drain

How to completely drain water from any water heater is interested in the owner who was about to clean the device from scale. The main mass is removed in one of the considered methods. But a part of the liquid remains inside the tank. To drain it under the boiler, the container is substituted, the nuts are unscrewed and the heater is removed. Through a large hole all the remaining liquid glass.

ways to drain water from a boiler

Today, the boiler began to be installed in almost every house, as this is a great opportunity to ensure a constant supply of hot water, regardless of how the water supply works properly. When operating the boiler, a variety of points can occur, for example, that urgent water drainage is required, for which you need to be prepared in advance. In this article, the master plumber will tell you how to drain the water from the boiler.

  • During the departure from the house (cottage) of temporary residence. This is necessary so that during frosts the icy liquid does not break the storage tank;
  • During an emergency shutdown of the general water supply. Water in Boyler is 50-100 liters of liquid for household needs (using the toilet, washing hands, dishes);
  • If a leak is found in Boyler;
  • To remove the unpleasant smell of stagnant, rotten water. If the water heater has not been used for a long time, then a very fetid smell appears. It is necessary to drain the entire liquid, and then fill the tank, turn on the maximum heating and emptily it again;
  • If noise is heard during operation or an RCD often triggers;
  • For cleaning the tank from scale or multiplying bacteria. The first appears due to excessively hard water with regular fluid heating to high temperatures. And bacteria appear if the boiler is constantly heated to low temperatures;
  • To replace the magnesium anode. This part of the water heater must be changed annually, since the anode protects the device from corrosion, attracting all harmful impurities to itself.

If the accumulative boiler is in a heated building, then it is not necessary to drain the liquid during the departure. the frost is not terrible. But there is another problem that can show itself. stagnant water. It all depends on the design of the unit:

upper, connection, boiler, drain
  • If the accumulative tank is made of stainless steel, then it is not worth draining water, since the liquid does not corrode it, but wet air, on the contrary, promotes corrosion;
  • If the inside of the water heater is made of copper, then it is better to devastate it before leaving, since hard water quickly corrodes the tank;
  • If you use a centralized water supply, then it is not necessary to drain the heater, since the water from the common highway contains chlorine impurities that disinfect the liquid, preventing the occurrence of unpleasant odor and the multiplication of microorganisms;
  • The water from the home well does not contain chloride impurities, so it quickly stagnates and the smell of rot appears, so in this case, the liquid should be removed from the water heater before leaving.

Water Heater. Drain Valve | Repair and Replace

note! If the boiler is under warranty, then you cannot drain the water! Otherwise, warranty obligations will become invalid

Anyone who has already drained water from the boiler knows that this process depends on many nuances: type of connection, operating conditions, design features, frequency of use of the heater.

Before draining water from the boiler, the device must be disconnected from the power supply network. Then you should wait until the liquid in the heater has cooled to room temperature.

As a rule, the water heater is mounted on supports or wall. Flexible hoses or tubes for cold (input) and hot (output) water are connected to the boiler below.

Hot water can be poured out of the tank only with the simultaneous filling of the device with a cold liquid. If cold water does not enter the device, then hot fluid does not flow even with an open tap. This is the peculiarity of this unit. Therefore, it is necessary to wait for a complete cooal of the water heater.

When the liquid has cooled, you need to open the entrance for cold water, as well as ensure the flow of air inside the device through the output for hot flow. How to do this depends on the connection option and design features. Consider 5 ways how to drain water from the water heater.

Installation of the boiler in accordance with the rules implies the presence of a descent safety valve. which is installed at the entrance to the water heater. This device automatically drains the fluid from the tank in the event of an emergency, when the pressure in the device exceeds the specified values.

The safety valve is equipped with a nose for connecting a drain tube and a screw in the form of a handle for opening and closing the device. It is recommended to open an emergency valve once a month even for no apparent reason to check its performance.

Reset through a safety check valve

This method is recommended to use all well.known manufacturers of water heating tanks. Ariston, Thermex, Gorenje, Electrolux and so on. The household device is connected to the water supply networks according to the scheme (presented above) from the instructions for operation:

How to Winterize a Sprinkler System. Blow Out Method

  • A security group for boilers is installed on the input pipe;
  • A shut.off crane is placed in front of the group;
  • On the output pipe, the reinforcement is not provided or mounted by the ball valve.

Explanation. The security group is an automatic element of 3 in 1, this includes the valve reverse safety drain valve with a plastic lever.

  • We block the water line at the entrance to the apartment, turn off the heater from the mains.
  • We release 1-2 liter through the nearest mixer, opening the DHC valve until the end. We leave the plumbing device in the open position so that the air can fill the void in the tank.
  • We substitute a bucket for the “nose” of the valve, turn the lever and slowly empty the tank.

Before devastation, the heating device does not need to be disassembled and wait until the water has cooled. Disadvantages of the method:

  • Due to the small passage section of the nose (5 8 mm), the water runs too slowly, the boiler is 80-100 liters empty in about 2 hours;
  • The valve often clogs, does not pass the liquid poorly;
  • Sometimes a security group acidifies, the drain does not work at all.

The method is suitable for small water heaters of 25-50 liters, provided that the valve valve operates normally. Lowering large volumes will come out for too long.

Rapid emptying through the HVS pipe

To rather lose water from a boiler connected according to the factory instructions, you will need a pipel (gas) or a divorce key. We will disconnect the pipes, otherwise. Procedure:

  • We are waiting for the full tank to cool, or turn off and use the heated water as much as possible.
  • Close the feeding of the CVS to the house, release part of the water from the mixer, leave the crane open. Again, turn off the power supply of the water heater.
  • We unscrew the gas key both eyeliner to the boiler. It is worth substituting a bucket so as not to fill the floors and other items under a hot water apparatus.
  • We grab the key behind the valve and slowly unscrew. We cover the hole of the “hot” pipe with your finger, otherwise the air will freely pass into the container, the water flows in the stream.
  • Finally twist the security group, put a bucket below and release a finger. If you need to stop the stream, again plug the boiler hot water pipe.
  • Before assembling and filling the tank, clean the pressure discharge valve (preferably blow).

Advice. It is more convenient to produce manipulations when there is a tap on the output fitting. You can find a valve with ½ “(internal) thread in advance, wind it instead of a pipe removed and adjust the air supply/water flow.

The advantage of the method is the speed of emptying, the procedure will take a maximum of 30 minutes. Negative moments:

upper, connection, boiler, drain
  • Dismantling is required. at least the CVS pipe must be removed;
  • The water heater must be cooled, otherwise you will burn;
  • The pressure from the fitting is difficult to control, the vacuum does not work right away.

The expiration of water can be slowed down. not disconnected from the boiler HVS highway. Air enters the mixer slower, the flow goes intermittently. How the Atlantic 80 liters water heater merge, look at

Will there be water in the boiler?

Experts express the opinion that it is not worth fear that water inside can deteriorate. The long.stored during the opening of the crane will flow out, and the received new portion will be ready for use. Many manufacturers do not recommend draining, arguing that, in its absence, the tank affects corrosion faster. As a result of changes in the internal environment, the material is oxidized faster.

From all accumulative boilers, they are drained the same. There are some differences that depend on the individual features of the design of units of various companies. The drain from the water heaters Thermex (Termex) is advisable to perform through the pipe. A crane is unscrewed from the cold water supply pipe, a hose is screwed to this place, which is lowered into the sewer. In horizontal models there is a special air cork, which is opened when draining. In vertical, to supply air inside the container, shut.off valves are twisted from the hot water pipe. But if the drain valve is additionally installed during the assembly, it open it.

In the units of Ariston (Ariston), the drain is carried out, as in the vertical Thermex, except for the Eureka model. In it, at first, taps are dismantled from the pipes of cold and hot water, a built.in mixer is removed. Under the cladding, the air supply is found, which is unscrewed and the water will merge.

In modern models there is a “anti.frozing” mode, systems of dry heating elements, stainless steel tanks, in which anticorrosion elements are presented. or high.quality enamel. All this allows you to less often drain.

What to do if you need to quickly drain the water

Often, users try to drain the water in an emergency man, for example, with a non.working discharge valve. For this, it is necessary to act as follows:

  • Completely block the tap of the cold line (this can be done at the base of the pipeline, or immediately in front of the boiler, if there is such an opportunity).
  • Open the valve of hot water to align the pressure inside the container.
  • Follow the bucket under the cold pipeline and unscrew the pipe using the installed fitting.
  • Be sure to open a hole for connecting with a hot line.

In order to stop the flow of water, it is necessary to block the flow of air through a hot pipeline.

Features of water drain from a boiler of different brands

The organization of hot water supply using high.quality water heaters is considered a rather reliable. But sometimes you have to get rid of the recruited fluid, for example, to clean the electrical appliance or when it fails. On the example of popular brands, we will consider how to empty the water heater without resorting to the help of specialists.

Boiler from TC “Ariston”

  • Disconnect the device from electricity and wait until the water reaches the optimum temperature so as not to get a burn.
  • Cross the water approach to the boiler using a specially installed regulator.
  • Open the hot water crane on the closest mixer to the boiler. This will make it possible to penetrate the tank.
  • Turn the airborne crane to the “VCL” position, after which open the drain crane, with which water will fail.

To completely clean the inside of the electrical appliance, you will have to completely remove the heating device. Ideally, it must be boiled in a metal container, adding citric acid.

The boiler from the brand “Thermes”

For safety reasons, you need to turn off the device from the network, only then continue the actions.

  • We block completely inpatient water supply, remove the tubes that supply the water to the heater.
  • If a flat.type boiler is used, it is enough just to stop the water supply and pour the remaining through a hot crane on the mixer.

The principle of drain, depending on the volume of the heater and the complexity of its design, may differ.

Electrolux water heater

Models of boilers from the Electrolux trademark merge several times easier than any other model. Usually, the release is carried out through a drain valve.

In more detail the plum algorithm watch in the video.

The principle of operation of the device

To figure out how to drain correctly, it is worth understanding the principle of action and the distinctive qualities of the equipment. It includes a container (tank), which is most often made of corrosion-resistant steel. An electric heater, air carrier and tube are connected to the container. To heat the heat, the thermal insulation layer is provided. For functioning in automatic mode, a thermoregulator is installed in the housing.

In devices with a small tank, the upper feed is usually carried out (the hole is absent). To drain the liquid, the device needs to be removed and turned over, which is not very convenient. If there is a drain hole, also, it is not always possible to easily drain the liquid. If you block the input of cold water and open the boiling water tap, then a small part of the water will come out of the watering device to a specific level located at the upper point of the hot water. For the complete elimination of water, it is necessary to create a suitable position for oxygen intake inside the container. For clarity, you can find and see how to drain the water from the boiler on the video.

Methods of complete elimination of fluid

The drain from the watering device can be carried out by one of three methods:

The first methodology is resorted to the presence of a tee and a pipe, but extremely rare. Acting clearly according to the instructions, it is required to block the water at the input. To eliminate it from the tank, you need to use a crane located next to the pipe and a control pipeline reinforcement.

The second methodology is resorted to in the presence of a special lever. To eliminate the liquid, it needs to be bend. For the speed of the procedure, the hose is connected to the control pipeline fittings to remove water through the plumbing (for example, a bath, a sink).

The last methodology is resorted to with a check valve recorded for an emergency reduction in pressure in the watering device. Unscrew it with caution, because with a significant amount of liquid, the pressure will first be strong, but then it will decrease sharply.

Important! In a situation, if with an open valve the liquid does not leave the watering device, you will need to look at the wiring of boiling water, since oxygen can do exclusively with open wiring. To simplify the drain, it is allowed to use the hose.

Equipping the boiler and draining liquid

Before you properly drain the water from the water heater, you need to understand its equipment. The accumulative water heater includes:

  • enameled tank (also made of stainless steel);
  • internal tubes;
  • tubular electric heater with thermostat;
  • Automatic airborne.

As a rule, tanks of such equipment are designed for a certain pressure. About 7-10 bar. It turns out that the device of the heater is a special capacity operating under pressure. And if there is still water, then drain it just like that, just opening the valve. will not work. Since only part of the water will flow out without air supply from the structure. The liquid will leave, which is located near the tube with a DIS.

And now about how to drain water from a storage water heater. This can only be done by supplying air to the system. This process is carried out through hot water supply. We will analyze by stages:

  • It is necessary to block the valve of cold water to the water heater.
  • Open the DHW contour (say, crane in the kitchen) and slow down slowly.
  • Take a small cross and twist the flag fixed in the safety valve of the cold liquid. The valve itself supplies water to the equipment.
  • After twisting, you need to raise the flag and at the same time prepare a niche where water will be collected. The capacity must be put under the safety valve. It happens that with professional installation there is already a pipe instituted under pour out. It should be attached to the sewer.
  • If everything is fine, then there should be enough atmospheric pressure so that water circulates due to the air leaks through the hydroelectric power pipe. You can hear the movement of bubbles inside the contour with warm liquid. Here the system is already prepared, it is necessary to drain gradually, change the container under the water heater (it is allowed to open and close the safety flag). However, atmospheric pressure often fails.
  • You may need disassembly. It is necessary to process the nearest connective part from hot water to the water heater. It’s good when the disassembled connection does not come out of the equipment.
  • If the model does not imply disassembly, then a rubber hose of suitable diameter is taken, put on a crane, which is closest to the boiler. It is necessary to blow into the hose so that the remaining liquid flows into the water heater. You can take both the pump and the compressor, but here it is already more complicated.

A good option is to immediately put a boiler with easily separated joints. Quite convenient in country conditions. Smart users set a tee of water drain for a water heater in advance.

Scheme for placing valves of water drain from a boiler

There is a tube with cold water in the boiler, located not at the very bottom. Therefore, a certain part of the water may remain when pulling. This is better to take note if you have to leave the equipment for the winter unattended in the cold room.

How to drain water from the water heater in the country completely? This is done only by twisting the heating element. Everything that did not move through the tube will go through the hole for installation.

How to drain water from the boiler Termyx

Termyx is a popular manufacturer of home water heaters. The company’s devices have established themselves as high.quality and reliable. Before draining the water from the Thermex boiler, you should get acquainted with the design features and the nuances of manufacturing. The main devices for draining the liquid will be a rubber hose and a gas valve key. The process of draining water from the thermex boiler looks like this:

  • The key is blocked by the key through which cold liquid circulates into the water heater.
  • Then the hot liquid opens on the mixer to create a vacuum.
  • You need to wait a little while all the water comes out. It will take about 1-2 minutes.
  • After the complete drain of the liquid, the water heater arrow will be at zero, and the tap will need to be closed.
  • It is required to slowly unscrew the nuts with a divorce key, in the place where cold water is introduced. When unscrewing, the liquid will not be the oven again.
  • Now you need a rubber hose. It is connected at one end to the contour of cold water to the water heater, the second end is sent to the sewer or prepared capacity. It is required to disconnect the withdrawal of hot fluid from the heater. Now the liquid should flow down the hose.
  • Now finally unscrew the nut of fixation of the output of hot water. The air will begin to pass into the system, and the hot liquid will merge completely.

Water did not immediately begin to merge? Gright in the hose. After the tolling of water, you will only need to tighten the nuts back and that’s it. The disadvantage of this method is only in the maximum volume of the liquid, which will be possible to drain, it is 2 liters.

Watch the video on how to drain the water from the water heater Termyx.

How to drain water from Ariston water heater

Another demanded brand is Ariston boilers. Why focusing on the products of this manufacturer is focused? Because here already draining water is carried out according to a more complex method. As a rule, certain tools are prepared: a wretched key or a divorce 32 and 24 mm, a direct screwdriver and a hexagon of 4 mm.

Now let’s move on to how to drain the water from the ariston boiler:

  • It is necessary to close the water tap for a boiler.
  • Open the DHW contour on the mixer. This is required to reset pressure inside the tank.
  • Open the crane on the pipe of connecting hot water supply to the water heater so that the air can get into the tank.
  • Open the liquid drain tap from the boiler. Before that, turn off the drainage hose.
  • After you figured out how to drain the water from the ariston boiler, check if all the liquid has completely removed.

Do everything in stages, and you will definitely do everything right and efficiently, and the equipment will last you for many years.

Some recommendations

After all of the above, the question of whether it is necessary to drain water from the water heater, should not stand.

  • When the water heater itself is disconnected before the arrival of winter, it is not recommended to drain all the water from the tank. If the heater itself is not afraid of cold weather, then it is better to leave a little water inside. So you protect the structure from the corrosion process. The liquid is also useful if someone wants to include equipment in the mains. Because an empty tank heats up quickly, which can provoke a fire.
  • If the device was a certain time turned off, and the water in it stagnated a little, then experts also do not advise to completely drain it. It is better to update stagnation, adding to a full tank. The water heater should be maintained every three months, drive out at least 80 liters through the structure.
  • If the equipment still extends to the equipment, then it is not recommended to repair something independently, even small parts, it is not recommended. So you just lose a guarantee. If problems arise with a watering structure, be sure to wait for the masters who themselves will merge the liquid, eliminate the breakdown. After all, under warranty, it’s all free.

Now you know how to remove the boiler and drain the water from the electric water heater. Remember that any brand of equipment implies similar actions by plums, such as disconnecting from the network before starting work, blocking the water supply, and so on, however, some brands have their own nuances that should be taken into account.

I want to give advice at the end. When you disassemble and assemble a water heater, be extremely careful not to damage rubber gaskets or plastic elements. Otherwise, you risk violating the integrity of the structure, and the boiler will flow, while the search for new rubber gaskets will take a lot of time.

Other methods of draining water from the water heater

There is another method of water removal. In this case, the crane is blocked through which the liquid enters the unit, open the mixer and remove the water. On the valve opens the “flag”. The disadvantage of this method is that the liquid comes out for too long. The reason is that air enters the container, which prevents the removal of fluid.

You can solve the issue if you remove the pipe from hot water. At the same time, the valve should be twisted with special accuracy to avoid damage to the thread. Before starting the operation, it is recommended to drop a couple of drops of machine oil to the valve. This will protect against its damage when unscrewing.

Before starting work, it is necessary to make sure that:

To lower the liquid completely and do this correctly, you should definitely familiarize yourself with the device of the water heater, which consists of the following elements:

  • internal container;
  • thermal insulation;
  • decorative coating;
  • control device;
  • electrical cable;
  • temperature.

A magnesium anode is an important node that needs to be changed every two years. It is designed to effectively soften water, counteract the formation of lime deposits. Ten is a special element that heats up with water. It is made of tungsten or nichrome spiral. She, in turn, turns into a copper casing. This design allows you to quickly heat the liquid with the maximum efficiency.

The quencher does not make it possible to mix cold and warm water. The regulator allows you to heat the liquid up to 76 ° C, hold the constant mode. If the temperature reaches 96 ° C, then a special relay turns off the system automatically. The tube that is responsible for the water fence is located in the lower part, and the liquid is drained through it.

Must be a marking of the entrance and exit. On the pipe is the gasket of the blue tint, the output is marked in red. To drain water according to all the rules, you must definitely study the device diagram that is often applied to the purchase.

The most popular connection is with a tee. In this case, a special tee with a crane is placed on the highways between the device and the valve. The safety valve is necessarily present. He is responsible that the water does not return back if it is absent in the circuit itself. Shut.off tap prevents the drain of hot water from the unit.

The practice of accumulating water using a tee is very common. This method makes it possible to simply and effectively remove the remaining water without using any tool. If everything is done correctly, then the liquid can be removed from the container in ten to fifteen minutes.

This is done as follows:

  • The unit is de.energized;
  • water supply is blocked;
  • A crane supplies hot water opens;
  • Water is removed from the tube through the mixer;
  • the hose is put on, the crane on the plum is unscrewed;
  • The blocking reinforcement is closed.

It is impossible to allow air to fall into the channel, otherwise the drain will last a long time. As already mentioned, the air works as a cork and prevents the active removal of the liquid.

Flushing after draining water from the water heater

Washing the boiler is necessary. Water should not stagnate, otherwise deposits form on the wall of the water heater, which are very difficult to remove. If the accumulative water heater did not work for a long time, it is recommended to skip 8-10 buckets of water through it, for this you must first remove the lid. Repeat such a procedure should be once a month. Running water removes pathogenic microorganisms, improves the operation of the entire heating system.

Before starting the boiler, it is necessary to check whether the crane with hot water is closed, as well as the crane through which the liquid goes out. If the tee is mounted on both sides, then this option is quite suitable.

In this case, the algorithm for carrying out the work will be like this:

  • The tap is overlapped;
  • the drain hose is mounted;
  • The mixer opens to weaken the pressure and remove the remaining water;
  • The valve on the tee is unscrewed.

All actions must be done in a strictly defined order, only then is it possible to achieve the desired result.

Plum through the safety valve

The Boiler connection scheme necessarily provides for the installation of a single.controlled safety valve on a cold water supply pipe or another pressure valve. The valve has several functions. So, it is needed to prevent hot water from getting from the boiler into the supply of cold. Otherwise, without a valve or if it is faulty, the boiler may be empty, and the water in the flushing tank of the toilet will be hot. From the point of view of hygiene, this can be useful, but very uneconomically, and the boiler without water will fail, his hets will burn out.

Another valve function to prevent the destruction of the boiler when heating water. With an increase in temperature, the water increases in volume, the pressure in the funded capacity increases. The valve drops the pressure in the boiler, removing part of the water. So the heater will remain both unharmed and safe for a person, even in case of water heating to prohibitive values.

And the modern valve design allows you to use it to drain water from the boiler. To do this, a lever is provided in its design, pressing on which you can remove water through the hole in the valve body. This method loses the removal of water from the boiler through the drain crane, since the water through the valve will flow for a long time, a thin stream, because the reverse safety valve has other tasks in the priority. Therefore, drain the water through the safety valve only in the absence of a drain crane.

Water removal if there is no drain crane and valve

Often, owners of water heating boilers are deprived of the opportunity to get rid of water in it through a crane or a safety valve. This happens, for example, if inept plumbers forgot to install a drain valve in the connection diagram of the boiler, but did not forget to fasten the checkpoint valve of the outdated structure without the function of draining water from the boiler. In this case, water from the boiler can be drained, but it will be more difficult to do it.

To do this, the supply of water into the boiler is also previously blocked. Drain the water, simply unscrewing the hose of cold water to be possible, the safety valve will not allow the water to escape from the boiler. Therefore, to drain the water, you will need to dismantle the valve and then lower the water from the boiler through the released entrance of the cold water into the boiler. Of course, the keys will be required, the size of which depends on the size of the valve nut. You can use the plumbing of the plumber. Hot water should remain blocked. Then you should carefully twist the valve from the highway until water starts to drain from the boiler. Its pressure can be adjusted by blocking the message of the hot water pipe with the atmosphere. It is tedious to drain the water so, so when installing the accumulative water heater, it is worthwhile to worry in advance and about the drain crane, and about the safety valve of the desired type.

And the last, strict rules that will ensure the safety of water removal from the boiler:

  • Be sure to turn off the boiler power when draining water from it, and with any maintenance of it.
  • Be sure to block the supply of cold water into the boiler, if there is a need to get rid of water in it.
  • drain water only after its temperature inside the heater becomes room.

Subject to the proper installation of the water heater, these rules will drain water from the boiler an ordinary service procedure.
