  Test for leaks at this point: Close the Needle Valve (turn needle handle clockwise all the 
way in to close) Turn ON the cold water supply to the sink faucet. If the Needle Valve or the 
Adaptor leaks, check the connection and try applying more Teflon tape or tighten the brass 
nut some more to stop the leak.
Step 2: Drain Saddle Installation
Note:  To avoid annoying 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 horizontal tailpiece . To reduce the drainage noise, mount the drain line as low as possible 
above the trap, or on the horizontal tailpiece. 
 Fig. 6 
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.
