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).
Caution: 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 .
STEP 1
Punch a Hole for the Faucet in a Stainless
Steel Sink
Note: If mounting faucet to a Stain-
less 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 .
