Step 1: Install the three-way feed water ball valve
Locate the cold water supply stop valve under the kitchen sink. Turn
the incoming cold water off (typically by turning the valve in clockwise
direction). Turn on the kitchen faucet to release any pressure in the pipes
and to make sure the water has stopped before proceeding to the next
step.
The cold water supply stop valve 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.
Once you have ensured that the cold water supply is turned off,
disconnect the cold water riser hose tting from the cold water supply
stop valve that you just turned off. Using an adjustable wrench, loosen
the nut (typically by turning in a counter-clockwise direction) 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 ball valve. The three way feed water
ball 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 threads
of the three-way feed water ball valve and attach the cold water riser
hose to it. Use the thread seal tape to wrap the threaded stem from the
cold water supply stop valve coming out of the wall and gently screw the
three-way ball valve on over the tape. Make sure that both connections
are secure, but do not over tighten or you can damage the ttings.
If your pipe connection is 1/2”, the three-way feed water ball valve is
3/8”, but comes with a 1/2” converter for your convenience.

Step 3: Install the drinking water faucet
Installation
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. If there is no pre-drilled hole, please consider
hiring a professional, since some kitchen countertop materials may require
specialized tools. The hole should be at least 7/8” in diameter and no greater
than 1-3/8” in diameter.
Place the pop-up rubber gasket and base on the counter over the hole and
place the stem of the drinking faucet through in the order shown in the
illustration. The stem of the drinking faucet should be accessible from under
the sink.
Place the silicon washer onto the threaded stem and secure under the
counter by placing the 3/4” mounting nut on threaded stem and tightening the
mounting nut until the faucet can’t move freely.
Locate puried water output line (white PE tube) and insert into the drinking
water faucet quick-connect tting and ensure that it is secure. Once secured,
slide the locking clip into place.
Certain faucet models may not be equipped with a quick-connect tting.

Select a location on the drain pipe that is at least 3” straight length of
pipe, preferably on a horizontal plane (B), for drilling a 1/4” hole through
one side of the drain pipe.
Next, align and install the 1/4” drain saddle’s quick connect tting with
the drilled hole. Attach the drain saddle to the drain pipe and tighten the
two screws. Once the drain saddle is secured, push the waste water
drain line (yellow PE tube) through the quick-connect tting on the saddle
and insert the locking clip to secure the yellow PE tube in place.
Do not connect the other end to the Purlette system at this time
Align the holes of the drain saddle and drain pipe with a drill bit.
