Feed Water Installation; Drain Saddle Installation - Abundant Flow Water Systems RO/DI Combo System Installation & Service Manual

Feed Water Installation:

1. The feed water assembly consists of a 1/2" slip joint adapter
with 2 washers and an angle ball valve. Locate these parts in
the installation kit. If space permits, the angle valve should be
installed into the slip joint adapter before connecting the
assembly to the feed water line (Note: Teflon tape must be
used on angle valve to prevent leaks).
2. Locate cold-water angle shut off valve underneath the sink,
usually on the right side, and turn it off. Open cold water faucet
to release the pressure. On single handle faucets, the hot water
may need to be turned off to prevent any hot water from
crossing over. If water continues to come out of the faucet with
angle valve turned off the main water supply will have to be
turned off.
3. The slip joint adaptor is usually installed on the cold water
faucet shank, but may be installed on the cold water shut off
valve. (Figure 2) If installing on the cold water shut off valve, an
adapter will most likely be required. Use the following
instructions for your particular plumbing type.
Flex line Instructions
Loosen nut and separate cold water line from faucet shank. Insert the flat washer into the slip
joint adapter, and gently bend flex line so that the slip joint adapter fits onto faucet shank and
tighten slip joint adaptor to faucet shank. If washer in flex line is worn or damaged, replace
before continuing to prevent any leaks. Re-install cold water line onto slip joint adapter and
tighten. (The cone washer is not used in flex line installations)
Copper Instructions
Loosen nut and separate cold water line from faucet shank. You will need to cut a piece of the
copper tube about 3/4" to 1" (measure to determine the exact cut needed) so the slip joint
adapter can fit between faucet and the copper line. Insert the flat washer into the slip joint
adapter and tighten onto cold water faucet shank. Insert the cone washer into the slip joint
adaptor and push the copper pipe into the washer and adaptor and tighten down the
compression nut. Make sure you use plenty of Teflon tape on all connections.
4. Once the system is ready to be hooked up, the feed water line will connect to the angle ball
valve. To connect, place the nut and ferrule (white plastic ring) over the feed water line, insert
the line into the angle valve, and tighten the nut.

Drain Saddle Installation:

The drain saddle consists of two (2) halves, (one half has a fitting on it), two (2) bolts with nuts, &
a rubber seal. It is used to direct the waste water from your system down the drain. Depending on
where the saddle is located, you may hear water running down the drain when the system is
making water, this is normal. If the sound is annoying, the drain line may be pushed farther in to
