Step 1 - Drill a Hole into the Sink for the Faucet
Notice:
If your sink is equipped with a pre-drilled 1 ¼” or 1 ½” hole suitable for the faucet
installation, you may skip to step 2.
Notice:
Manufacturer assumes no responsibility for damages resulting from installing faucets
into any surface. It is recommended to use a licensed contractor for this step.
For this, step, you will need:
Masking tape or duct tape
Variable speed drill with
⅛
” and 7/16” drill bits
1-¼” hole saw bit for faucet opening – appropriate for the surface you are drilling
Determine the desired location for your RO Faucet
The product water faucet may be installed on any flat surface at least 2” in diameter. Check the underside
of the location for interference. The standard faucet that is supplied with the system requires a ½” diameter
hole. The optional air-gap faucet requires a larger hole of ¾” to allow for the additional tubing connections
required.
Stainless Steel Sinks
Begin by placing a piece of masking tape or duct tape on the determined location where the hole is to be
drilled. Make a small indent to mark the desired drilling location using a center punch. Drill a pilot hole with
a
⅛
” metal drill bit. Enlarge the hole using a ¼” metal drill bit, using factory approved method or approved
plumbing practice.
Porcelain/Enamel Sinks or Tile Countertop
Sinks of this type are very easy to damage due to the nature of the materials of construction. A successful
installation into these sinks requires a knowledgeable technician with the proper cutting tools. We strongly
recommend the use of a “Relton” type device. Follow the directions that accompany the tool carefully.
