WATER FEED SOURCE AND REJECT DRAIN CONNECTIONS
6
FEED WATER CONNECTIONS:
The feed water connection to the Galley-Mate marine
water purification system will vary from vessel to
vessel, depending on vessel size and type of piping
used on board.
We include a 1/4” Self-Piercing valve that is normally
used under the galley sink on vessels that have the
cold water faucet piped with rigid copper risers.
(See figure 1-A.)
Today, many vessels use quick connect plastics for
fittings and connectors along with the plastic tubing
that is available with specialty fittings such as those
supplied by Neptune Plumbing Systems, on a wide
range of production boats. For connection to plastic
tubes, we recommend locating a “T” with ball valve
(not supplied) to make the 1/4” connection to the Gal-
ley-Mate Feed Water port.
(See Figure 1-B)
Other connection fittings
are available. Feed connec-
tion can be achieved with
shut off of a variety of
styles. Although pre-filter
has a built in shut–off a
feed water shut off is re-
quired for a proper install.
DRAIN CONNECTIONS:
All Membrane Purification Systems have one feed water
inlet and two outlets, a purified water stream and the
reject drain stream. The reject flow must be taken to a
drain, which will vary from vessel to vessel.
We include a standard drain saddle valve which fits any
1 1/2” OD straight wall pipe. This fitting may be used in
under galley sink installations where the riser above the
“P” Trap is 1 1/2” in diameter. This fitting can be in-
stalled either in a vertical position or on a horizontal
position as long as the fitting is above the trap. When
installing the Galley-Mate assembly in an engine room
you may utilize the saddle fitting on any non– pressur-
ized straight wall pipe such as PVC. Do not install into
any pipe sections that are pressurized or in the position
of holding water in a void. ( See Figure 1-C ).
Select location for the drain clamp. Position the threaded
1/2 of the saddle on pipe and mark the pipe through the
threaded opening. Drill a 1/4” hole at marked location
into pipe.
On board drain connections will vary depending on the
location for the installation of the system. Different
adaptors may be utilized when draining to an existing
thru-hull drain line. On some vessels, with larger fresh
water tanks and frequent water-maker fills from sea wa-
ter, the RO drain may be diverted back to the fresh water
storage tank for a “O” waste system. If the TDS is low
in the tank, the rise of TDS from the RO will be insig-
nificant to the tank volume. We recommend our Water-
Mate systems if this drain connection is used. Ask your
Distributor for Water-Mate product data.
