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 Teon 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.
Step 4: Check the leaks and ush the lter
1. In the event of water leakage, turn o the water
supply. If the water leakage is occurring at position
1, wrap Teon 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
ttings. If not, insert it again until you reach the
mark on the tubing.
2. Flush the lter for 5 minutes before use.
To disconnect
Use your thumb and index nger to press down on the lock sleeve. Use your other hand to pull out the
hose from the tting.
Note: Please do not pull out the tubing directly, or else it will damage the tting and cause leakage.

Q: Why doesn’t the TDS value lower after ltration?
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 benecial trace elements. Please choose Waterdrop RO
system if you are looking for physical removal of TDS.
Q: When should I replace the lter?
A: The lter's service life is related to water quality. If the ow rate is signicantly 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-UF, WD-RF10-MZ, 2 years for WD-RF15-UF, WD-RF15-MZ, 3 years
for WD-RF17-UF, WD-RF17-MZ.
Q: Why does black water come out during ushing?
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.
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 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.
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.
WARNING
Please read it carefully before installation.
The system and installation shall comply with applicable state and local regulations.
