Step 2: Drain Saddle Installation
Note: To avoid possible drainage noise, mount drain line as low as possible on the
vertical tailpiece, or on horizontal tailpiece.
There is constant water pressure “packed” inside the RO system which blocks the waste water from
backing-up into the system. So the waste water is “forced-drained”, not “gravity-drained”.
1. See Fig. 6. The drain saddle assembly should be installed above the trap and on the vertical or horizon-
tal tailpiece. To reduce the drainage noise, mount the drain line as low as possible above the trap, or on
the horizontal tailpiece.

2. See Fig.7. Mark the position of the hole on the drain pipe and drill a 1/4’’ hole through one side
of the drain pipe. There is a piece of self-adhesive sponge provided. Glue this sponge to the inside
of the saddle, this will cushion any gap between the saddle and the pipe. Make sure the hole on the
sponge is thoroughly punched out, and is aligned to the hole on the saddle.
