The dishwasher is associated with regular heating of the water, which is accompanied by the formation of scale. The harder the water, the more difficult it is for the ion exchanger to cope with its softening and the faster the wear of parts. We will find out if water hardness in Moscow is suitable for a dishwasher.
About stiffness standards
Stiffness is an aggregate parameter that depends on the amount of salts concentrated in the liquid, mainly calcium and magnesium. There are two types of living matter - permanent and temporary. They cope with the first by bringing to 100 degrees - salts are eliminated by settling and forming a calcareous deposit (scale). This is enough for a person, but not for a car.
In the Russian Federation, water hardness (hereinafter referred to as LH) is measured in “degrees of hardness”. In Europe, other units are used. 1 ° W = 1 mEq / L.
In Russia, the maximum standard level of hardness is 7 mEq / l. In Europe, more stringent standards.
Life indicators in Russia:
- soft - up to 4 mEq / l;
- average - from 4 to 8 mEq / l;
- hard - from 8 to 12 mEq / l.
In free access there is a map of Moscow with the indication of livestock by region. In a matter of seconds, you can figure out this indicator - just look at the map and find your place of residence on the map.
Water with increased hardness in appearance and taste is no different from normal - you cannot visually distinguish it. But there are signs by which a person can guess about an increased concentration of salts:
- dry skin of hands, dryness and fragility of hair;
- limescale on plumbing and electrical appliances.
Because of the scum, household appliances often fail, you have to change components and parts, or even change it to a new model. In the elite technique there is a function of automatic determination of stiffness, the machine itself calculates how much salt needs to be added to reduce the concentration of substances. In ordinary dishwashers there is no automatic detection, and the user needs to set the level on his own so that the PMM takes the necessary amount of salt with each wash.
What is the hardness of tap water in Moscow
Many Muscovites do not suspect which water flows from their taps - hard or soft. The degree of LH in different places of the capital is not the same - it depends on the quality of work of specific treatment plants. Indicators are inconsistent and may change over time.
The average LH in Moscow is 5.5 mEq / L. This value, according to the norms of SanPiN, refers to the middle range. But there are areas in which this indicator is much higher (South and South-West) - it reaches 9-10 mEq / l. This level is dangerous for household appliances.
Living conditions in the districts of capitals, degrees of rigidity:
- in the Central - 3.3;
- Northeast - 3.4;
- North - 3.6;
- Southeast - 3.2;
- East - 3;
- South - 3.5;
- Southwest - 3.4;
- Zelenogradsk - 3.5;
- Western - 3.5;
- North-West - 3.1;
- Novomoskovsk - 3.1;
- Troitsky - 3.2.
Who is responsible for the capital's water?
JSC Mosvodokanal is responsible for the qualitative characteristics of water in Moscow. Samples are taken here every two weeks - if there are less than 10,000 people in the area. The larger the population, the more often samples are taken. Separately, samples are carried out after repairs of water supply networks. Every citizen can make a request to this organization about the characteristics of water.
How to find out about water quality?
To obtain reliable and relevant information on water parameters at the address, you can go to the Mosvodokanal website. Here it is necessary to enter the section "Population", and then in the subsection "Water Quality in the Areas of Moscow". Here you must specify your address, in a second the current value will be shown to the user.
Residents of the capital can monitor the status of tap water online. All indicators are inconsistent and dynamically changing, therefore it is impossible to rely on fixed indicators.
Not all Muscovites can track water supply parameters. People living outside the MKAD are not available the service described above. Therefore, they have to find out the degree of LH independently - for example, using stiffness strips. This is a very convenient and quick way to determine - just lower the strip into the test fluid to get an answer.
What do the indicators depend on?
Most often, changes in indicators are related to the time of year. The harshest water flows from taps in the cold season. It is during this period that dishwashers and washing machines are in the greatest danger.
In spring, the water in the water supply is softer - thanks to melt and rainwater entering the general water system. In summer, the level changes depending on the circumstances, but in autumn the water is again soft - due to heavy rainfall.
To accurately know the concentration of hardness salts and other impurities in water, it is better to send it to the laboratory for analysis. This is especially important if you have to install a cleaning system in the cottage.
Knowing how soft or hard water flows from the tap, the user can protect his dishwasher from the negative effects of salts. A correctly set level of stiffness will prevent scale formation and will extend the life of parts in contact with water, and the entire apparatus.
