Common Problem

Q: The output of water purifier is weakened

There are many temporary factors that will lead to the decrease of the water output of the water purifier (such as abnormal water pressure of the tap water, blockage of the filter element of the water purifier, etc.). Generally, the decrease of the water output occurs. First of all, we need to check whether it is the problem of the water pressure of the tap water; If the water pressure is normal, it means that there are many particles in the water, which makes the filter element of the water purifier blocked. In this way, we need to replace the filter element or contact the service personnel of the water purifier company to take corresponding measures.
Q: After not using for a long time, the water quality became worse

This is a normal situation. If the water purifier is not used for a long time, the residual water in the water purifier will cause the growth of bacteria, so when it is used again, the water purifier needs to be washed repeatedly before it can be used.
Q: After the filtered water boils, white precipitate will be produced

The prominent point in the purification function of reverse osmosis water purifier is that the precision is about 0.0001 μ m. It is like a sieve and can basically filter 98% of bacteria and viruses in water. Therefore, in the concept of many people, the water from the water purifier will not produce white sediment, but the water quality is also divided into hard water and soft water, even if the hard water is filtered by the water purifier, it is still hard water. It can't change the essence of water quality, but after hard water boiling, the compounds in hard water will decrease with the increase of temperature and solubility, resulting in the condensation and precipitation of minerals or suspension in water after boiling. In addition, this phenomenon sometimes occurs in cold water, which is related to the alkalinity of water. However, the white sediment formed by the rise or fall of water temperature does not affect the quality of water, so there is no need to worry.
Q: A thin film will be formed on the surface of tea after water purification

Water purification tea will form a film on the surface because of the high mineral content in the water in this area, and another major feature of the water purifier is that some minerals will be retained in the effluent. When the minerals in water and theophylline, tea polyphenols in tea, etc; Antioxidants and other natural compounds will form a film on the water surface. The film formed by this natural substance is good for human body, so please don't worry.
Q: The water from the water purifier still has scale

There are two categories of general household water purifiers: one is ultrafiltration machine, whose main function is to remove sediment, rust, bacteria, suspended solids, algae, macromolecular organic matter and other harmful substances that may be contained in water, and to retain minerals that are beneficial to human body. Therefore, it is a normal phenomenon that there will be scale in the burned water in the area with serious scale. Another main function of the water purifier is to filter out the rust, sand, colloid and other harmful substances in the water, and at the same time, it can absorb the heavy metal substances such as viruses and bacteria in the water. Very poor water quality can also become direct drinking water.
Q: Long term accumulation of dirt produces secondary pollution

If the pollutants accumulated for a long time in the water purifier are not discharged in time, it will produce secondary pollution in the filter element of the water purifier. Therefore, the physical filter elements such as PP cotton and activated carbon should be replaced in time.

Q: The produced water of water purifier has peculiar smell

A. the residual chlorine in the water has peculiar smell. The residual chlorine has bactericidal effect and the water purifier can be used normally. B. the water purifier has been out of service for a long time (repeatedly invading before reuse to remove the stagnant water in the water purifier). C. if the water purifier is not washed for a long time, the entrapment will form scale in the filter element.
Q: What is the suspended matter in tap water?

The suspended matter in water is particles with a diameter of more than 1 ~ 4mm, which are mainly composed of sand, clay, protozoa, algae, bacteria, viruses and high molecular organic matter. Turbidity of water is also caused by such substances. These particles are very unstable and can be removed by precipitation and filtration. Suspended matter is the main source of turbidity, chroma and odor. Its content in water is also unstable and often varies with seasons and regions.
Q: Why is the water reduced and the taste bad after a period of time?

In China, the land area is wide and the water quality varies greatly between the north and the south. Most of the surface water has high mineral content and turbid water quality. In this case, the life of the water purifier may be shortened, resulting in the reduction of water production. Activated carbon is characterized by adsorbing bacteria to improve the taste. When your taste has a peculiar smell, replace the filter element.
Q: How loud is the water purifier?

The water purifier can use electricity or not. If the use of electricity sound, that is the water purifier inside the pressure pump in operation, is a normal phenomenon. If the water purification products do not use electricity, the sound is loud, indicating that there is a problem with the internal parts of the machine
