Drill a Hole for the Reverse Osmosis Faucet
Marble Counter-top
We recommend contacting a qualified contractor for drilling a hole in a marble counter-top.
Counter Top / Porcelain & Stainless Steel Sink
Most sinks are pre drilled with 1 ¼" diameter hole that you can use for your RO faucet.
Note:
(If you are already using it for a sprayer or soap dispenser, see step 1)
Porcelain sinks are extremely hard and can crack or chip easily.
Use extreme caution when drilling. Watts accepts no responsibility for
damage resulting from the installation of faucet. Diamond tip bit recommended.
Step 1
Determine desired location for the RO faucet on your sink and place
a piece of masking tape over where the hole is to be drilled. Mark the
center of the hole on the tape.
Step 2
Using a variable speed drill set on the slowest speed, drill a 1/8" pilot
hole through both porcelain and metal casing of sink at the marked
center of the desired location. Use lubricating oil or liquid soap to keep
the drill bit cool (If drill bit gets hot it may cause the porcelain to crack
or chip).
Step 3
Using a 1 ¼" diamond tip hole saw, proceed to drill the large hole. Keep
drill speed on the slowest speed and use lubricating oil or liquid soap
to keep the hole saw cool during cutting.
Step 4
After drilling, remove all sharp edges and make sure the surroundings
of the sink are cooled before mounting the faucet.
Mount the Reverse Osmosis Faucet
Step 5
Feed both the red and black tubing through the pre
drilled hole in the sink/counter until faucet is seated.
Under the sink - on to the threaded faucet stem in this
Step 6
order first slide on the split washer, white spacer with
the open end UP, the plain washer, the lock washer,
and lastly secure with nut.

Step 7
Locate the blue 1/4" tube in the parts bag. Remove a brass nut, plas-
tic sleeve and plastic insert from the faucet parts bag. To assemble,
place the brass nut on the blue tube first, then the sleeve (small
tapered end of sleeve must point to the end of tube) and then push
the plastic insert all the way into the end of the tube. (See Picture)
Step 8
Push the assembled blue tube into the faucet stem until it stops. Slide brass nut and plastic
sleeve down until you can thread nut onto the stem. Use a wrench to securely tighten the
brass nut while continuing to push the tube into the stem.
