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.
Using a variable speed drill on the slowest speed, drill a
1
/

” 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).
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.
Make sure the surroundings of the sink are cooled before mounting the
faucet to the sink after drilling. Remove all sharp edges with a fi le.

Step 2
Drill a Hole for the Faucet in a Porcelain Sink
Most 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, you will need an
additional hole for the faucet).
Porcelain sinks are extremely hard and can crack or chip easily. Use extreme caution when
drilling. Premier accepts no responsibility for damage resulting from the installation of
faucet.
Punch a Hole for the Faucet in a Stainless Steel Sink
Step 5
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.
Drill a ¼” pilot hole. Use the appropriate sized hole punch and an
adjustable wrench to punch the hole in the sink.
Once the hole is punched out, the faucet can be installed.
