STEP 1
Drill a Hole for the Faucet in a Porcelain Sink
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 A).
NOTICE
Porcelain sinks are extremely hard and can crack or chip easily.
Use extreme caution when drilling. Watts accepts no responsi-
bility for damage resulting from the installation of faucet.
Step A –
Determine desired location for
the RO faucet on your sink and
place a piece of masking tape
on over where the hole is to be
drilled . Mark the center of the
hole on the tape .
Step B –
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 C –
Using a
1
⁄
2
” 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 D –
Make sure the surroundings of the sink are cooled before
mounting the faucet to the sink after drilling and remove all
sharp edges .
Punch a Hole for the Faucet in a Stainless
Steel Sink
If mounting faucet to a Stainless Steel
Sink you will need a
1
⁄
2
" Hole Punch.
The faucet opening should be centered
between the back splash and the edge
of the sink, ideally on the same side as
the vertical drain pipe.
Step A –
Drill a ¼" pilot hole . Use a
1
⁄
2
"
Hole Punch and an adjustable
wrench to punch the hole in
the sink .
The faucet can now be installed .
