Step 3 - Drain Saddle Installation
Notice:
Some states require the use of an air gap faucet. Check your local plumbing code to
assure compliance.
For this step you will need:
o
Masking tape or duct tape
o
Variable speed drill w/
⅛
” and ¼" drill bits
o
Phillips
Screwdriver
o
Drain saddle assembly supplied with system
o
Yellow tubing cut to appropriate length
Select Location for Drain Saddle Installation
Select a location for the drain hole based on the design of the plumbing.
It should be installed above the trap and on the vertical or horizontal tail
piece. To avoid possible drainage noise, mount drain line as low as
possible on the vertical tailpiece.
Notice:
Do not install downstream of a garbage disposal,
as this can cause contamination and system
fouling.
Drill a ¼” Hole in the Drain Pipe
Starting with the
⅛
” drill bit, drill a
⅛
” hole in the drain pipe. Use the ¼” drill bit to enlarge the hole. Clean the
debris from the pipe and the hole before continuing.
Notice:
Take extreme caution to not drill through to the other side of the drain pipe.
Install the Drain Clamp
Apply the foam gasket inside the front half of the drain saddle: Punch out the cut-out hole in the center of
the pad, remove the adhesive backing, and adhere to the inside of the drain saddle, ensuring the holes
are aligned.
Place one half of the plastic drain saddle assembly on each side of the drain pipe with the fitting, and
clamp loosely using the nuts and bolts included.
Align the hole drilled in the drain pipe with the hole in the drain saddle.
Make sure to align the drain
saddle hole to the drilled hole perfectly
. Mis-aligning these two holes will block the drain water and
cause membrane damage. A drill bit or other long narrow object may be used to
help align correctly.
Use Phillips screwdriver to tighten the clamp. Avoid over-tightening.
Connect Drain Line to RO System Reject Line
Insert the yellow tubing to the pipe stop in the quick connect
fitting on the drain line and check the seal.
Connect the other end of the yellow tubing to the flow
restrictor outlet coming from the membrane brine port.
