Frequently asked questions
Q: What should I do if water leaks after installation?
A: In the event of water leakage, turn o the water supply. If the water leakage is occurring at the
thread, wrap Teon tape on the external thread. If the water leakage is occurring at the quick
connection position, insert the quick-connect tting to the end and make sure the hoses hit the
bottom of the tting. Contact us for solutions if the water leakage persists.
Q: Why doesn’t the TDS value lower after filtration?
A: The main purpose of this waterdrop lter 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 lter can
remove harmful substances while keeping benecial trace elements. Please choose Waterdrop RO
system if you are looking for physical removal of TDS.
Q: When should I replace the filter?
A: The lter's service life is related to water quality. If the ow rate is signicantly reduced or if the
water has a peculiar smell, we suggest that you replace the lter. The recommended service life of the
lter is as follows: 1 year for WD-RF10, WD-RF10-UF, WD-RF10-MZ and WD-RF10-AK, 2 years for
WD-RF15, WD-RF15-UF, WD-RF15-MZ and WD-RF15-AK, 3 years for WD-RF17, WD-RF17-UF,
WD-RF17-MZ and WD-RF17-AK.
Q: Why does black water come out during flushing?
A: It’s normal that black water comes out when ushing. The purpose is to remove carbon powder
remaining on the surface of lter materials. You can normally use it after ushing for 5 minutes.

this reason, mechanical devices such as water ttings, lter head, and faucets have a limited replacement
assurance of 1 year. No assurance is given as to the service life of any lter cartridge, as the service life will vary
based on local water conditions and water consumption.
