STEP 2: TAPPING INTO COLD WATER LINE
1) Locate cold water angle shut off valve underneath the sink and turn it off. Open cold water faucet to
release the pressure. On single handled faucets, the hot water may have to be turned off to prevent
any hot water cross over. If water continues to come out of faucet with angle valve turned off, the
house main will have to be turned off.
2) Locate feed water adapter in the installation kit. The angle needle valve should be installed into slip
joint adapter (VV-WWC-1) before assembly is connected to feed water line. See <Fig. 3> (Teflon
tape must be used on angle valve to prevent leaks).
3) Disconnect the cold water riser tube and install the slip joint adapter.
Caution: The water supply to your unit MUST be from the COLD WATER LINE.
Hot water will severely damage your R.O. System.
4) Please follow by <Fig. 4> for flex line and solid copper riser installation.
a) Flex line:
Loosen nut and separate cold water riser tube from faucet shank. Gently bend riser tube so that
slip joint fits onto faucet shank. Replace the existing cone washer with new washer provided in
installation kit onto cold water riser tube. Reinstall riser tube onto slip joint adapter and tighten.
b) Solid copper riser tube: Procedure as flex tubing except you must cut a piece of the riser tube
about 3/4” or 1” so the slip joint adapter can fit between faucet and riser tube (Teflon tape must
be used on slip joint adapter to prevent leaks).
5) Connect red tubing to the inline valve .
