Make sure the surroundings of the sink are cooled before mounting the
faucet to the sink after drilling and remove all sharp edges.
Step 3
Step 4
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 1
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).
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 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.
Step 5
The faucet can now be installed.
If mounting faucet to a Stainless Steel Sink you will need a 1/2”
minimum 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:
Most sinks are pre drilled 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. Premier accepts no responsibility for
