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 remain-
ing 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.
Step 4: Check the leaks and flush the filter
1. In the event of water leakage, turn off the water supply. If the water leakage is occurring at position 1, wrap
Teflon tape on the external thread. If the water leakage is occurring at position 2, 3 or 4, check whether the
tubing is fully inserted into the fittings. If not, insert it again until you reach the mark on the tubing.
2. Flush the filter for 5 minutes before use.
