INSTALLATION - FEED WATER SUPPLY
REJECT WATER DRAIN FITTING
Check and comply with local plumbing codes
as you
plan, then install a cold feed (supply) water fitting. The
fitting must provide a leak tight connection to the RO
1/4" OD tubing, see Figure 6, Page 10. A typical installa-
tion, using standard plumbing fittings is shown in
Figure 1. A saddle valve (part no. 7011272) is available
to use where codes permit. Installation instructions are
on Page 24.
NOTE:
Codes in the state of Massachusetts require
installation by a licensed plumber, and do not permit
the use of the drain clamp. For installation, use plumb-
ing code 248-CMR of the Commonwealth of
Massachusetts.
PIPE FITTINGS
(compression shown)
IMPORTANT:
Before starting, close the hot and cold
water shutoff valves (See Figure 1). Use a pan to catch
water when disassembling the pipe.
Complying with plumbing codes, install a fitting on the
kitchen cold water pipe to adapt 1/4" OD tubing. A typ-
ical connection is shown in Figure 1. You can use solder
or threaded fittings. If threaded fittings are used, be
sure to use pipe joint compound or Teflon tape on out-
side threads.
Do not connect the tubing to the fitting until Step 2, top
of Page 10.
Running the RO drain tubing directly to a floor drain,
laundry tub, sump, standpipe, etc., is preferred. If that
is not possible or practical, check and comply with
local plumbing codes as you plan, then install a drain
fitting for RO reject water. This fitting is usually
installed at the sink p-trap (always above). It must pro-
vide a leak-tight connection to 3/8" OD tubing from the
RO product water faucet airgap, see Figure 6, Page 10.
Typical drain fitting installations are listed below. A
drain adapter (part no. 7192230) is available to use
where codes permit. Installation instructions are on
Page 24. Other options are shown on Page 27.
“Y” BRANCH TAIL PIECE, OR OTHER APPROVED
P-TRAP DRAIN
Reject water from the RO is routed to the RO faucet air-
gap (1/4" tubing), then to the drain point with 3/8" OD
tubing. COMPLYING WITH PLUMBING CODES,
install a fitting to accept the 3/8" tubing. Figure 2 shows
typical p-trap and "Y" branch tail piece type drains.
Do not connect drain tubing until Step 1, top of Page 10.
