Installation Tips
How to Use the Quick-Connect Fittings
To connect:
1. There is an existing mark (Figure 1)
at the end of the tubing that you can
use to conrm whether the tubing
is fully inserted into the tting. Push
the tubing into the tting until you
reach the mark on the tubing.
2. If the tubing is not fully inserted, it
will cause leakage. When the tubing
is fully inserted, put the blue lock clip
on the tting. It will lock the tubing in
place and prevent it from falling off.
3. If the tubing is too long, cut it to a
suitable length using a sharp utility
knife or pair of scissors. Cut the
tubing squarely and cleanly (Figure
2). Make sure the tubing is fully
inserted.
To disconnect:
1. Remove the blue lock clip from the
tting.
2. Use your thumb and index nger
to press down on the lock sleeve.
Use your other hand to pull out the
tubing from the tting (Figure 3).
NOTE: Please do not pull out the
tubing directly, or else it will damage
the tting and cause leakage.

How to Drill a Hole into Your Sink or Countertop (Optional)
NOTE:
• Please conrm if there is an existing hole available to install the faucet. If not,
please drill a hole in accordance with the following steps.
• If the countertop is thicker than 2.95 inches, the faucet cannot be installed. It’s
highly recommended to watch the YouTube video “How to Drill Faucet Holes”
for a better understanding of the process. There is also a sticker for your
reference when you drill the hole. Remember to wear safety glasses to protect
your eyes while drilling the faucet hole.

Step 1:
Install the Feed Water Adapter (3/8" or 1/2")
Installation Steps
NOTE:
• Before installation, remove the RO system from the box and choose an easy-
to-access area under the sink to place it. An adequate at area is necessary to
allow the system to rest securely. Do not lay it on its side, on its back, or upside
down.
• Also before installation, ensure that there is a power outlet in the cabinet or
on the wall connected to the lower cabinet space. Additionally, ensure that the
system does not share the same power outlet as the garbage disposal.
• The RO system must be connected to the COLD water supply ONLY.
• Do not install the system where it will be exposed to direct sunlight or harmful
chemicals, nor in any place where it may be damaged.
• Do not install the system near any heat source.
• Do not install the system outdoors.
Prior to installation, it is highly recommended to watch the video “Waterdrop
D6 RO

” on .
1. Choose a diamond core bit for granite, and a carbide drill bit for stainless steel.
Do not use a hammer drill on natural stone, glass, or ceramic.
2. Glue the sticker to your sink or countertop, and drill a hole referring to the size
shown on the sticker (1⅜").
3. Make an indent with a center punch on a stainless-steel sink before drilling to
help guide the bit.
4. Be careful when drilling on a porcelain sink, as it can be easily chipped. Apply
downward pressure rmly to the bit until breaking through the surface.
5. Starting at the lowest speed, hold the drill straight with rm pressure to prevent
the bit from walking on the counter.
6. Once breaking through the surface, swirl the drill a little to apply pressure in a
circle evenly.
1. Shut off the water supply. Turn on the faucet to release the water pressure.
NOTE: Make sure the water has stopped before proceeding to the next step.
Use a towel or bucket to catch any excess water.
2. Disconnect the cold water pipe from the cold water supply valve.
3. Connect the white 1/4” inlet water tubing to the feed water adapter and pop the
lock clip on the tting.
NOTE: Make sure it is fully inserted until you reach the mark on the tubing.
4. Tighten the converter. Twist the feed water adapter onto the cold water supply
valve (with its washer) and tighten it using an adjustable wrench (Figure 4).
NOTE: If the cold water pipe is 1/2”, unscrew the converter from the A end of
the feed water adapter, and then screw it on the B end of the feed water adapter
(Figure 5). Next, follow step 4.
5. Twist the cold water pipe (with its washer) onto the feed water adapter and

reset button and power button will be on, and the outlet water ow will return
to normal.
3. Turn on the faucet, and allow it to run for 20 minutes. After ushing, the system
is ready for use. The system will drain residual water after every use to ensure
the system’s service life and ltered water quality. Every time you turn on the
faucet, the system will need some time to dispense water. There may be a
3-second delay before water dispenses, which is normal.
NOTE:
• Be sure to carefully check the tightness of each part of the system while
ushing. Ensure that all the tubing is installed correctly and completely. Make
10
sure there are no leaks at the joints, ttings, valves, or tubing connections.
• The water will be undrinkable during the ushing process. The water might
appear black at rst.
• You will need to do the timekeeping for the 20-minute ushing yourself. Note
that when the system continuously works for over 40 minutes, it will enter
timeout protection mode. The lter indicator light will ash and the system
will not be able to dispense water. Press the power button for 3 seconds. The
lter indicator light will turn off. Then press the power button for 3 seconds.
The system will return to normal.
4. Before turning off the faucet, make sure the ushing is complete and that there
are no leaks in any of the parts.

treatment device should be installed before the installation of this system.
• The feed water pressure of this system is 14.5-87 psi. If the water pressure is
• Applicable water quality: municipal tap water.
• The feed water pressure of this system is 14.5-87 psi. When the water pressure
is lower or higher, install a pressurizer or a pressure reducer accordingly.
• The recommended temperature range of the product is 39-100°F. Do not install
the system where the ambient temperature and water temperature are higher
than 104°F or below 32°F.
• Check whether the tubing connected to the system is incorrect and aging.
• Make sure all tubing is fully inserted to the point where you reach the mark on
the tubing.
• Use only authorized WD-D6-B parts and lters.
• Check the tightness of the feed water adapter and make sure there is no water
leakage.
• When the quick-connect tting leaks, do not replace only the lock clip. You must
replace the entire quick-connect tting.
• Do not omit any lock clips.
• Do not lay the system on its side, on its back, or upside down.
• Do not use a lter that has not been ushed. Flush the new lter for 20 minutes.
• Do not cut the tubing with tools other than a utility knife. Do not bend the tubing.
• Use the new quick-connect ttings that come with the system. The old quick-
connect ttings cannot be reused.
• Do not insert the drain tubing into the sewer. It must be connected to the
drainpipe using the drain saddle.
• A xed power socket of 110V is required. Ensure that the power socket and
adapter are in a dry place indoors to prevent moisture from accumulating in the
system.
Installation Precautions
15
lower or higher, install a pressurizer or pressure reducer accordingly.
• The ow rate will decrease when the ambient temperature is low, which is an
inherent characteristic of the lter.
• When the system is dispensing water, there will be a slight vibration and noise,
which is normal.
• This system is designed for indoor use only. A oor drain should be located
within 1.5 meters of the system to avoid loss caused by water leakage and poor
drainage.
• If the system will not be used for a long time, turn off the power and the feed
water adapter. Flush the system for 5 minutes before using it again.
NOTE: In the event of a water outage or pipeline maintenance, turn off the power
and the feed water adapter. When the water supply returns to normal, turn on other
faucets to drain the sediment. Then turn on the feed water adapter. Otherwise, a
large amount of sediment may block the lter. Replace and ush the lter regularly.
16
• The System Cannot Be Powered on After You Insert the Power
Plug
a. Check the power under the sink, as this occurs primarily when the power under the
sink is powered off. Also, check the connection between the power plug and the
power outlet to ensure that the system has been correctly plugged into the power
outlet. To test whether there is a problem with the system itself, simply pick up the
system and try another power outlet. Please contact us if the system cannot be
powered on. We will help you gure it out.
• No Output Water from the Faucet
a. The lter is expired: Check the lter life indicator to conrm whether the lter must
be replaced; if it does, replace it immediately.
b. Low water pressure: Check and conrm that the water pressure is between 14.5 psi
and 87 psi.
c. Water supply is off: Turn on the feed water adapter or the water supply valve.
d. Incorrect lter installation: Reinstall the lter and make sure it is tted into
properly.
e. A tubing is crimped: Check all the tubing and remove any crimps.
• Low Water Flow at the Faucet
a. A tubing is crimped or there is a leak from the tubing connection: Check to
ensure that all tubing is installed correctly and completely.
b. The lter is expired: Check the lter life indicator to conrm whether the lter
needs to be replaced; if it does, replace it immediately.
c. Low water temperature: Be sure to use the system at a temperature of 39-100°F.
d. The lter has been clogged: If you are using well water as the source, please
ensure that the feed water has been through a pre-ltration system. Otherwise,
large particles in the well water will easily clog the lter and shorten the lter life.
Troubleshooting
• High TDS in the Filtered Water
When working properly, the system will provide a 90%+ TDS rejection rate (tested
under standard laboratory conditions). If the TDS reading is high, the following are
possible causes:
a. The system hasn’t been used in a while. Turn on the faucet and allow the water
to run for a while. The TDS reading will return to normal.
b. The lter is expired: Check the lter life indicator to conrm whether the lter
needs to be replaced; if it does, replace it immediately.
c. The drain tubing may be crimped or clogged: Check and remove the crimps.
Realign the drain saddle and the drainpipe.
d. The source water may have a high TDS: Test the source water and the ltered
water. The ltered water’s TDS should be about 5%-10% of your source water’s
TDS. This is a normal range. If the source water has a high TDS, it may reduce
the system’s service life. When the ltered water’s TDS creeps up to 15%-20%
of the source water’s TDS, please perform routine lter replacement.
