Step 1: Install the three-way feed water adaptor valve
Locate the cold water supply valve under the kitchen sink. Turn the
incoming cold water off by turning the valve clockwise. Turn on the
kitchen faucet to release any pressure and make sure the water has
stopped before proceeding to the next step.
The cold water supply is usually located on the right-hand side.
However, to ensure this is the case, turn the hot water on for two
minutes. Feel both hoses with your palm. The hot water supply riser
hose should feel warm. The one remaining cool is the cold water supply.
Next, install the three-way feed water adaptor valve.
Once you have ensured that the cold water supply is shut off, disconnect
the cold water riser hose tting from the cold water valve that you just
turned off. Using an adjustable wrench, turn the nut counter clockwise
until disconnected. There may be some residual water inside the riser
hose so have a bucket or towel to catch it.
Now install the three-way feed water adaptor valve. The adaptor valve
has a top and a bottom that are threaded nut connectors with a side
quick-connect tting. Use the thread seal tape to wrap the threaded
stem from the cold water valve coming out of the wall and gently screw
the adaptor on over the tape. Next, repeat step above and reconnect the
cold water riser hose. Make sure that both connections are secure, but
do not over tighten or you can damage the ttings.

Step 2: Attach water line to three-way feed water adaptor valve
Now it’s time to connect the tap water input line to the three-way feed
water adaptor valve.
Locate the tap water input line (blue PE tube) and connect one end to
the three-way feed water adaptor valve by pressing the one end of the
tube into the quick-connect tting. Be sure to push it in all the way until
you feel it stop otherwise leaks may occur. Then slide the locking clip
into place to secure the tube. Pull gently to ensure that it is securely
attached.
If your pipe connection is 1/2”, the three-way feed water
adaptor valve is 3/8”, but comes with a 1/2”convertor for your
convenience.

Step 3: Install the drinking water faucet
When installing an additional faucet, many times there are already pre-drilled
holes available. Many sinks have a soap dispenser or spray hose hole that
can be used for this purpose instead, if desired. Please consider hiring a
professional if there is not a pre-drilled hole.
Simply place the drinking faucet housing on the counter or sink where the
pre-drilled hole is separated by the provided rubber gasket. The stem from the
faucet should be accessible from under the sink.
Place 3/4” washer onto the threaded stem and secure under the counter.
Place 3/4” nut on threaded stem and secure by tightening until faucet can’t
move freely. Give the nut a quarter turn with the wrench to ensure to that the
faucet stays in place.
Locate puried water output line (white PE tube) and press into the drinking
water faucet stem quick-connect tting and conrm that it is secure. Once
secure, slide the locking clip into place to avoid leaking
Certain faucet models may not be equipped with a quick-connect tting.
