The water purification equipment installed in my home is a backwashing coarse filter + end ultrafiltration filter. The former does not need to change the filter element, as long as the impurities are discharged through the drain pipe regularly. The latter has two filter cartridges that need to be replaced regularly: â–¶Primary filter PP cotton filter, replace it once every 3~6 months, the market price is 80 yuan (including on-site service fee); â–¶The main filter element is replaced once every 2 years, about 1000 yuan. The main filter is best replaced by a professional, the initial filter PP cotton filter is not necessarily, you can do it yourself. It is a trivial matter to save 50 yuan for door-to-door service fees. The key is to save time and not have to wait for the master to wait for the door. I changed the initial filter PP cotton this time, and it has been installed for 6~7 months, which exceeded the theoretical replacement cycle. Hey~ I am also lazy. I always think that how high the technical content of the filter is, and it is difficult to delay, it has dragged on for so long. As a result, I realized that it was so simple. Step1: Buy PP cotton filter This is nothing to say, according to the model of the home water purifier, online shopping or physical stores can buy. My household water purifier PP face filter, about 30 yuan a. Step2: Unscrew the filter cartridge cover This requires a wrench tool, which is a little difficult. When purchasing a water purifier, the wrench is equipped in the package and should not be thrown away as packaging materials. Pull the wrench up from the bottom of the filter cartridge, cover the filter cartridge, and then force it to open. It is best to work with two people, one with two hands holding the filter cartridge and the other with a force. Step3: Change PP cotton filter After unscrewing the cover, remove the PP cotton filter and pour off the water from the filter cartridge. Replace with a new PP cotton filter, then screw the cover back and finish. Note: When replacing the new PP cotton filter, be careful not to soil the filter and keep your hands clean. Because the water that this filter element touches is the water we want to drink later. After replacing the PP cotton filter, the front water purifier was also rinsed, and I will mention it by the way. 1. Close the main valve, which is the red valve in the first picture of this article. 2. Connect the drain pipe to the inside of the bucket and unscrew the backwash valve on the top of the front water purifier. The water will flush the impurities into the barrel, and it will almost flush out with a small bucket of water. This time, a lot of impurities were washed out, which was supposed to be caused by the road water pipe being cut off some time ago.
