STEP 1
Drill a Hole for the Reverse Osmosis Faucet
Note: Most sinks are predrilled with 11/2" or 11/4" diameter hole
that you can use for your Drinking Water faucet. (If you are
already using it for a sprayer or soap dispenser, see Step A).

Use extreme caution when drilling. Watts accepts no responsi-
bility for damage resulting from the installation of faucet.

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 .

drill bit cool (If drill bit gets hot it may cause the porcelain to
crack or chip) .
Step C –
Using a 1¼" diamond-tip hole saw . Keep drill speed on
the slowest speed and use lubricating oil or liquid soap to
keep the hole saw cool during cutting .
