In the event of water leakage, turn off the water supply. If the water leakage is occurring at the thread, wrap the Teflon tape around the external thread. If the water leakage is occurring at the quick connection position, insert the quick-connect fitting to the end and make sure the hoses hit the bottom of the fitting. Contact us for solutions if the water leakage persists. Why does the TDS value not decrease after filtration? The main purpose of this waterdrop filter is not to remove TDS. TDS stands for total dissolved solids, and it is basically composed of inorganic salts and a small amount of organic matter. The filter can remove harmful substances while keeping beneficial trace elements. Please choose Waterdrop RO system if you are looking for physical removal of TDS. When should I replace the filter? The filter’s service life is related to water quality. If the flow rate is significantly reduced or if the water has a peculiar smell, we suggest that you replace the filter. Why does black water come out during flushing? It’s normal that black water comes out when flushing. The purpose is to remove carbon powder remaining on the surface of filter materials. You can normally use it after flushing for 5 minutes.
