Make sure the surroundings of the sink are cooled before mounting the
faucet to the sink after drilling. Remove all sharp edges.
Step 3
Step 4
Determine desired location for the faucet on your sink and place a piece
of masking tape on location where the hole is to be drilled. Mark the
center of the hole on the tape.
Step 1
Using a variable speed drill on the slowest speed, drill a
1
/
8
“ pilot hole
through both porcelain and metal casing of sink at the center of the
desired location. (If drill bit gets hot it may cause the porcelain to crack
or chip), use lubricating oil or liquid soap to keep cool.
Using a 1 ¼” 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 2
Drill a Hole for the Faucet in a Porcelain Sink
Punch a Hole for the Faucet in a Stainless Steel Sink
Drill a ¼” pilot hole. Use a
1
/
2
” Hole Punch and an adjustable wrench to
punch the hole in the sink. Change to the 1 ¼” Hole Punch to enlarge
the hole.
Step 5
The faucet can now be installed.
If mounting faucet to a Stainless Steel Sink you will need a 1 ¼” 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.
Note:
Note: Some sinks are predrilled with 1 ½” or 1 ¼” diameter hole that you can use for your
RO 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 drilling. Watts accepts no responsibility for damage resulting from the installation of
faucet.
