In winter, the entire water supply system in empty houses needs to be released from water. This is one of the most important items for the preparation of pipes and water tanks for winter. But the draining of water from the water heater is not only planned, sometimes this is a consequence of force majeure. In order not to break the complex technique, it is recommended to familiarize themselves with all the methods of draining water from water heaters.
Causes of plum
The safety of the water supply system and the release of it from the water is necessary if the room is predicted in the room below 5 degrees. At such a temperature, water freezes, expands and deforms or breaks pipes.
- Manufacturers often advise not to leave the device without water for a long period, since contact with water for them is less dangerous than contact with oxygen. This rule does not concern the conditions for lowering the temperature.
- Even if the accumulative water heater uses all year round and decrease in temperature below the critical level does not threaten it, it is still at least twice a year it must be released from water and cleaned. Water of poor quality leaves on the walls of the reservoir of the raid, which serves as a refuge of bacteria, as well as fine sand.
- In addition to these two troubles, there is a problem of making a scale, which prevents the water heating in the tank. And the thicker this layer - the more difficult it will be more difficult to achieve the necessary water temperature over time, and the consumption of electricity will increase repeatedly.
To make sure that the water heater needs cleaning, it is recommended to check whether its state corresponds to the specified criteria:
- Weakened water pressure
- Water heater spends more time to heat water
- Unusual noise from the device, noise strengthening
- Time planned prevention
- Safety valve flows or vice versa - does not pass water
- Cleaning, replacement of component parts also requires the empty of the water heater.
Hare heater
Manufacturers do not recommend independent analysis of the techniques, because any interference in its work may affect the likelihood of refusal to subsequently serve it under warranty. If the warranty period has expired and representatives of service services, it is not possible that it is possible to still risk and merge water from the water heater. To do this, you will need:
- Hexagon 4 mm
- NO2 gas key, replaced by the usual divorce
- Rubber Hose Necessary Sizes
- Cross screwdriver
- Straight screwdriver
- Capacity for water collection
Debaming method:
- Before the start of the drain, it is necessary to turn off the heater from the power supply and overlap the cold water valve. If the heater has not yet cooled - the analysis is recommended to postpone to its complete cooling. You can speed up the decrease in its temperature, you can turn off the heating mode and putting cold water - it will dilute boiling water in its reservoir.
- The following steps are recommended to perform in a strict sequence to avoid breakdowns and damage. After turning off the water heater, it is checked by an indicator for the presence of voltage. Then separate the details covering the bottom. At this stage, the scale can fall out, which must be collected.
- Disconnect the pipe that supplies water into the boiler tank. At its place the pipe of the desired diameter is fixed, withdrawing its free end into the water collection container. The flow of cold water is interrupted and begin to supply hot through the mixer.
- As soon as the air will fall into the heater, water will be able to merge through the connected output hose. After replacing parts or cleaning the water heater tank, the hose supplying cold water is connected and attach all the parts previously removed earlier.
Features of various devices
Due to the ignorance of the characteristics of the water heater, some inexperienced repairmen face that after connecting the hose and opening the crane, water cannot leave the closed system. To avoid this, you need to understand exactly how the heating device is arranged from which pipe water is capable of flowing.
A pipe for water supply to the heater is always downstairs and on the nozzle on it can be easily determined by hot or cold water it serves. If the Gasket is blue, it means cold water in the pipe.
Further action scheme directly depends on the features of connecting this pipe. Methods for connecting several:
- Standard method.This method is used in virtually all water heating systems. With it, a tee with a crane is installed between the instrument and safety valve. For the descent of water at the same time, the type of system is not needed. With it, water after connecting the hose is completely merged in 10 minutes.
If the drain time is greater, then the air through the mixer does not enter the system and cannot displace water. Correct this with a hose with a heated water output pipe. - Superior connection type. With this type, the tee stands on both pipes and removal of water. Water from such a system with a simple opening of the mixer after putting on the hose to the outdoor tube. The pressure in the reservoir after the opening of the mixer is lowered itself.
- Simplified way. This method of assembly eliminates the presence of valves, which highly complicates work with this kind of heaters. To drain the water, its supply to the device is stopped, the mixer open and give water remnants dragging out of the hose for the output of hot water and only then the check box open on the valve, which allows to merge the bulk of water.
The main minus of this type of construction is that the water will merge more than standard 10 minutes.
In draining of water from the water heater, there is nothing difficult if the model and type of assembly are already known. It is easy enough to prepare tools and collect water. The most important stage requiring the maximum concentration is the final assembly.
