1. Observe the clarity of water-the color and clarity of water obtained by tilting the faucet of the drinking machine is one of the important indicators to measure the quality of water. If the water quality is turbid and there are substances floating, it is necessary to clean or replace the filter screen in time.
2. Odor detection-if the water smells or tastes bad, it may be polluted, so it is necessary to consider replacing the water source or equipment.
3. Measure PH value-pH value is one of the important indicators to measure water quality. The PH value of food-grade drinking water is generally controlled between 6.5 and 8.5. Too high or too low PH will affect human health. It can be detected by PH test paper or PH meter.
4. Understand the maintenance cycle-drinking water equipment needs to be replaced, disinfected or cleaned regularly. In general, it is recommended to replace the filter screen once every quarter, and clean or disinfect large equipment at least once a year.
5. Refer to the water quality safety standards-you can measure the quality of water according to the relevant national drinking water standards and local regulations, and refer to their prescribed indicators.
In a word, the quality of drinking water is related to people's health, so we should attach great importance to the supply and management of drinking water. When choosing a regular brand water dispenser, it is necessary to check it regularly and replace the maintenance parts in time, so as to meet the water quality standards and ensure people's healthy drinking water sources.
