Frequently asked questions
Q: What should I do if water leaks after installation?
A: In the event of water leakage, turn off the water supply. If the water leakage is occurring at the thread, wrap
Teflon tape on 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.
Q: Why doesn't the TDS value lower after filtration?
A: 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.
Q: When should I replace the filter?
A: 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. The recommended service life of the filter 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 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.
1 -year quality assurance
All mechanical devices with moving parts have a normal life span and will need to be replaced periodically. For this
reason, mechanical devices such as water fittings, filter head, and faucets have a limited replacement assurance of
1 year. No assurance is given as to the service life of any filter cartridge, as the service life will vary based on local
water conditions and water consumption.
If the product proves to be defective within 1 year from the date of purchase, please contact our customer service
department. During the assurance period, we will replace or repair any part that is deemed to be defective if the
product has not been subjected to tampering, alteration, or improper use after delivery, and has not been repaired
by the manufacturer.
We do not make any promises in the event of misuse, use in abnormal temperature conditions, conditions outside
those listed in the operating parameters, or use in commercial operations.
