How long can the filter element of the water purifier last and how to replace the filter element?

Water purifiers generally use five-stage filtration. After the use of time, impurities and organic matter will adhere to the filter element, resulting in a decline in water quality and even endangering the safety of drinking water. Therefore, the filter element should be replaced regularly. The service life of the filter element is shown in the following figure: (Only when the filter element is replaced in time can you drink healthy water) It should be noted that due to the different processes and structures, the service life of the filter element is also different, which is summarized as follows: Note: Different regions have different service life. The water quality, water consumption and climate are different, and the replacement cycle is also different. How to replace the water purifier filter element? -- The method is as follows: 1. Replace the filter element of the pre-filter. This filter grade is placed behind the water meter and can remove large particles such as sand and gravel in tap water. The replacement cycle is: about 3 months. For specific steps, please refer to the article 'How to Replace the Pre-Filter Element'. 2. Replace the filter element of the water purifier 1. Close the water inlet ball valve on the tee, and open the water purification faucet to empty the remaining water in the machine; 2. Hold the main filter element and rotate it laterally (inward) about 90 degrees, and take out the filter element downward; 3. Unpack the new filter element, take off the cover of the filter tip, align the machine head vertically and insert it upward, turn it laterally (outward) about 90 degrees to fasten it, and gently shake the main core to ensure that it is in place to prevent water leakage; 4. Open the inlet and outlet. The water ball valve, the water faucet is not closed at this time, the water will come out after a few seconds, and let it drain for 10 minutes. First, the filter element is activated to ensure the filtering function and prolong the service life. Second, there may be a small amount of activated carbon powder flushed out, resulting in dark color water waiting for it. 5. Observe whether the main core leaks, close the water tap after 10 minutes, and the installation is complete. When replacing the front three-stage filter element, first turn off the electroplating ball valve and the pressure bucket ball valve, and open the gooseneck faucet to drain the residual water in the pipeline. Open it, take out the old filter element, put in a new filter element of the same specification, coat the black 'O' ring above the filter housing with a lubricant such as Vaseline, and then put the 'O' ring into the groove in the filter housing Inside, in a vertical way, tighten the filter housing, try to avoid the displacement of the 'O' ring, and then open the electroplating ball valve and the pressure barrel ball valve. 3. To replace the RO reverse osmosis membrane, first close the electroplating ball valve, wait for ten minutes, unscrew the nut joint on the right side of the membrane shell, pull out the water pipe, then close the pressure tank ball valve, unscrew the nut joint above it, and put the Lead the water pipe into an empty bucket or washing tank, hold the reverse osmosis membrane tube tightly with the left hand, then clamp the old reverse osmosis membrane with pliers, and pull it out of the membrane shell forcefully. Insert the newly opened reverse osmosis membrane into the reverse osmosis membrane tube until one end of the two small black 'O' rings touches the bottom end of the membrane shell, and then screw the membrane shell cover tightly. Plug in the hose and tighten the fitting nut. Then open the electroplating ball valve, let the machine run for more than two hours, and make the system enter the normal water production state, then connect the water pipe to the pressure tank ball valve and open the pressure tank ball valve. Matters needing attention: 1. Check the length of the filter element: compare the length of the old and new filter elements. If the length of the new filter element is insufficient, it can be solved by adding a rubber pad. The rubber pad can be removed from the old filter core) (the rubber pad can be removed from the old filter core) 2. When placing the filter core of the household reverse osmosis pure water machine, pay attention to the correctness of the filter core, especially PP is easy to deviate, When twisting the filter bottle, you should feel it by your hand. The small T33 is marked with the direction of water flow. The direction of water flow is marked on it. 3. The filter element of the water purifier can be connected to the next-stage system after being rinsed after installation. When flushing, disconnect the pipeline of the next level. Only the ultrafiltration water purifier and the filter element can be connected after being rinsed after installation. In the system of the latter stage, when flushing, disconnect the pipeline of the next level, and the water inlet ball valve needs to be opened to flush, and the water inlet ball valve needs to be opened to flush. minutes, and then connect to the lower processing system after flushing. 4. The use time of the filter core depends on the water quality. Generally, it is 6-8 months. PP can be cleaned and used. Do not exceed 1 year.
