Drill a Hole for the Faucet in a Porcelain Sink

For the Air Gap Faucet (included), a 1 1/4" hole will be required. If using a non air gap
Note:
faucet, a 3/4" hole will be required.
Porcelain sink surface material is extremely hard and can crack or chip quite easily. Use
extreme caution when drilling. Flowmatic accepts no responsibility for consequential dam-
age resulting from the installation of faucet.
Most sinks are predrilled with 1 ½" or 1 ¼" diameter holes (if you are already using it for a
sprayer or soap dispenser, continue to step 1).
C a u t i o n :
Professional installation may be required for Granite or Corian surfaces.
Step 1 Step 1 Determine desired location for the faucet on your sink and place 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 2 Using a variable speed drill on the slowest speed, drill a
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.
Step 3 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 4 Make sure the surroundings of the sink are cooled before mounting
the faucet to the sink after drilling. Remove all sharp edges.

Punch a Hole for the Faucet in a Stainless Steel Sink

Note: If mounting faucet to a Stainless Steel Sink you will need a ½"
& 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.
Step 5 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 1/4" Hole
Punch to enlarge the hole.
The faucet can now be installed.
