Drill a Hole for the Faucet in a Porcelain Sink
For Marble Counter-tops, we recommend contacting a qualified contractor for drilling a hole in a
NOTICE
marble counter-top.
Note: Most sinks are predrilled with 1½" or 1¼" diameter hole that you can use for your Drinking Water faucet.
(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
NOTICE
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 1/2" 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.

If mounting faucet to a Stainless Steel Sink you will need a 1⁄2" Hole Punch. The faucet opening
NOTICE
should be centered between the back splash and the edge of the sink, ideally on the same side
as the vertical drain pipe.
Step 1:
Drill a ¼" pilot hole. Use a 1⁄2" Hole Punch and an adjustable wrench to
punch the hole in the sink.
Step 2:
The Faucet can now be installed
