When purchasing water purification equipment in advanced countries, manufacturers will randomly attach installation and operation and maintenance manuals. The public only need to operate according to the items described in the manuals. Certification units (in the United States is the National Health Foundation, NSF) will be tested according to the type of water purification equipment and related documents, and only the standard water purification equipment will be certified. In China, the national standard method (CNS) certification is the best water purification equipment, and the public should find a water treatment equipment manufacturer with perfect operation and maintenance manual and good after-sales service to purchase water purification equipment.

Every kind of water purification equipment is not omnipotent. Before purchasing, we should first understand the function of water purification equipment and the water quality of local tap water, so as to avoid waste of money and not get the desired effect of reverse osmosis water purification equipment. For example, some water quality is not suitable for reverse osmosis method. If chlorine or iron in water treatment equipment in Hangzhou is too high, the film may be damaged. If the iron content in water is too high, it will damage the effect of ultraviolet sterilization and water purification equipment. In addition, when using water purification equipment, the inlet temperature should be avoided to be too high. When the temperature of many water purification equipment or filter core is high, the treatment effect becomes worse, the material will be damaged and the service life will be reduced. When a new type of water purification equipment or unit (including activated carbon water purification equipment and cation exchange resin softener) is used, it should be soaked in clear water for at least 15 minutes or rinsed with clean water to remove impurities in the core. For reverse osmosis water purification system, the pre-activated carbon filter core and reverse osmosis membrane need about 20 liters of water to wash each to remove carbon particles and reverse osmosis membrane preservation solution.

The replacement frequency of the filter core of water purification equipment is usually known in the operation and maintenance manual provided by the manufacturer, but it must be noted that the water quality conditions and water yield used by the manufacturer are in standard condition. Users must pay attention to the local water quality and whether the daily water consumption is different from the manufacturer's data. If the higher the concentration of pollutants in raw water and the larger the water consumption, the higher the replacement frequency of filter core should be. Users must pay special attention to the possible causes, such as improper connection of pipes, rupture of pipes or filters, and replacement of pipes or filters when necessary, even if the replacement time of filters is not enough, but the quality of clean water is obviously changed, the taste is poor or the water production of the system is reduced. In addition, in addition to the operation instructions on the machine, if the naked eye judges that the filter core of the pre-granular material in reverse osmosis water purification equipment has seriously turned to yellowish, the replacement should be considered.

Generally speaking, the frequencies of tap water cleaning in areas with hard water quality (such as southern areas) are higher than those in soft water areas. Some distillation water machines have pre-or Post-Activated carbon filters, which also have a certain service life and must be replaced periodically with reference to the instructions. In order to reduce the inhalation of volatile gases in excessive water, it is necessary to avoid approaching the exhaust gas holes in the boiling process when operating the distiller. This should also be paid attention to when using the general drinking machine or electric hot water bottle, or even when boiling water.

Complicated water purification equipment, such as reverse osmosis water purification equipment system, can be entrusted to the manufacturer to maintain once every three months to half a year. When self-repairing or replacing the filter core consumables, when removing the pipeline or parts, marks can be made on the pipeline or parts to ensure that the correct position can be connected when reconnecting. The new reverse osmosis system machine or the machine that has just replaced the filter core should turn on the tap to make the water flow out and discharged for a period of time, so as to avoid pollutants entering the bucket. When replacing the filter core by oneself, it must be noted that after removing the filter core, the barrel in which the filter core is placed must also be cleaned to avoid the accumulation of mud and sand. When the filter core is loaded back, attention must be paid to check whether there is leakage.
