How to drain water: ways to independently drain liquid from a water heater

Problems associated with planned outages of hot water can be easily solved by purchasing a water heater. Like any household appliance, it requires regular maintenance. Emptying and cleaning the storage tank will help to avoid the formation of scale on the walls and to extend the life of the boiler. Doing this for the sake of experiment is undesirable. If the device is under warranty, then an attempt to drain the water from the boiler yourself may lead to the loss of the right to free repair.

The need to empty the tank

Before carrying out any work on cleaning the boiler, the pros and cons should be weighed. Manufacturers do not recommend emptying the water yourself without good reason. For preventive purposes, cleaning is carried out once every 3-5 years.

Leaving the water heater in an unheated room at temperatures below +5 ° C with a full tank is fraught with water freezing and damage to the device. In this case, the liquid will have to be drained from the boiler without fail, as well as during its transportation or breakdown.

Modern titans are equipped with a magnesium anode, which prevents the formation of scale and corrosion. After 1-2 years of regular use, the anode, which takes on the negative influence of salts and other aggressive impurities present in any liquid, becomes unusable. Replacing it yourself also requires emptying the drive.

In other cases, it is not recommended to leave the tank empty. The design of the water heater provides for a sealed storage device that does not allow the metal parts of the device to rust. TEN and other parts in an empty drive become unusable faster due to contact with oxygen.

Storage water heater device

Methods for emptying the tank may vary slightly for different brands of heaters. Regardless of the manufacturer, design or storage capacity, any boiler is equipped with:

• Heating element;
• temperature sensor;
• hot and cold water outlets;
• anode;
• tank;
• outer casing.

To protect the heating element from overheating, a check valve is provided in the design, which does not allow the liquid to be completely drained through the tap.

When installing the device, specialists usually install a relief valve, which is screwed on separately from the fluid supply hose and greatly facilitates its draining if necessary.

The main way to drain

With the correct connection of the storage boiler to the water supply system, it takes five minutes to drain the water from the titanium. If the relief valve is installed separately from the supply and drain hoses, and the titanium itself is divided into two mixer (for example, on a bathtub and a sink), then you need to open a cold one on one of them, and on the other - hot water. On the water heater itself, you also need to unscrew the taps feed - blue and red. You must first shut off the water supply to the apartment and disconnect the device from the network.

If the relief valve is installed on a cold supply and connected to a tee, then you need to:

1. Disconnect the heater from electricity.
2. Close the cold tap (usually blue).
3. Put the hose on the drain cock, which comes out of the tee, and open it.
4. Open hot water on the mixer.

The contents of the boiler are drained into the connected hose.

Normal Connection Actions

If there is no valve and pressure relief lever, then you will have to completely unscrew the cold water supply hose. In this situation, it is better to have an assistant. You will also need a bucket, which must be substituted under the boiler. After disconnecting the power supply to the device, you need to:

1. Close fluid inlet valves.
2. Place the bucket under the titanium.
3. Unscrew the hot water outlet hose.
4. When part of the contents of the tank is drained, you need to unscrew the supply hose from the cold pipe.
5. Unscrew the valve.

To replace a full bucket, the drain holes will need to be plugged with improvised means or simply with your finger. This method is quite time consuming, therefore, when installing the device, it is advisable to check the presence of a relief valve.

Precautionary measures

Working with any electrical appliance requires caution. It is possible to safely drain the water from the boiler, without damaging the heating element or other parts, only when the device is turned off.

Do not empty the drive yourselfif it is under warranty. A specialist from the service center will do it faster and better. Watching his work, you can look and remember for the future how it is done.

If you call a specialist before emptying the tank, it is not possible, then you should make sure that the water in the water heater has cooled down to a safe temperature.

Electric Titans are completely sealed. Any unprofessional intervention can break the tightness, which will lead to the complete unsuitability of the device for further operation.
