Drill a Hole for the Faucet in a Porcelain Sink
Note:
Porcelain sink surface material is extremely hard and can crack or chip quite easily. Use
extreme caution when drilling. Premier Manufactured Systems accepts no responsibility for
consequential damage resulting from the installation of faucet.
A dripping or gurgling sound may be heard coming from the Air Gap hole in the faucet when the
system is running. This is normal and in compliance with UPC Plumbing Codes.
Most sinks are predrilled with 1 ½" or 1 ¼" diameter holes (if you are already using it for a
sprayer or soap dispenser, see step 1).
See the Faucet Installation section for the proper size hole to drill for a non air gap faucet.
Determine desired location for the faucet on your sink and place a piece
Step 1
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
Step 2
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
Step 3
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 with a file.
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.
Drill a ¼" pilot hole. Use a ½" Hole Punch and an adjustable wrench
Step 5
to punch the hole in the sink.
The faucet can now be installed.
