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 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 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 pilot hole & use the Hole Punch and an adjustable wrench to punch the hole in the sink.
Step 5
If mounting faucet to a Stainless Steel Sink you will need a 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.
Adapt-a-Valve Installation
Turn off the cold water supply to the faucet by turning the angle stop valve completely off.
Step 11
Step 12
Attach the adapt-a-valve as illustrated in the three photos above, choosing the configuration
that fits your plumbing. (When attaching the adapt-a-valve to straight pipe threads, use Teflon
tape on the threads without the rubber washer.)
Caution: Water supply line to the system must be from the cold water supply line only.
Hot water will severely damage your system.
