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.

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.

To disconnect

Use your thumb and index finger to press down on the lock sleeve. Use your other hand to pull out the 
hose from the fitting.

Note: 

Please do not pull out the tubing directly, or else it will damage the fitting and cause leakage.

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-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 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.
