Reassembly: Before you begin reassembly of the watermaker, clean all parts using clean, lint-free
rags. At this time, all parts should be carefully inspected for wear or damage. Use a 10x magnifier or
loupe to examine the seals, o-rings and other small parts. Stubborn rust stains and deposits on metal
parts may be cleaned with a soft-metal wirebrush (e.g., stainless steel or brass). Do not use polishes,
cleaning compounds containing abrasive materials, or regular steel wire brushes. Refer to the exploded
drawing of the pump in Figure A-2 in the Appendix for the location of parts and seals during
reassembly. Refer to Figures A-3 and A-4 in the Appendix for full-size drawings and identification of
the components included in the Repair Seal Kit. In the following procedure, references to the Repair
Seal Kit will be abbreviated to RSK.” It will be assumed that all o-rings, seals, and mating surfaces
have been lightly lubricated with non-petroleum silicon grease (supplied with the RSK).
Warning: Use only non-petroleum silicon grease to lubricate your watermaker parts. Lubricants
with a petroleum base will damage several watermaker components, including the reverse osmosis
membrane. Be especially cautious of lubricants that “contain” teflon, silicon, etc.such products
could also contain petroleum-based components. An ample supply of silicon grease is included with
each RSK.
Reinstall the piston: If you want to replace the O-rings on
the piston, refer to the figure below
Install washer with chamfer on washer
facing ½ dia of plunger rod and a new
O-ring onto the plunger rod, if you have
an old-style piston, you only have to
install a new O-ring into the plunger rod
without a washer.
Slide piston onto the threaded end of the
plunger rod, and secure with the washer
and nut.
1. Refer to Figure R-5 during the following procedure.
Place the piston assembly on a flat, stable surface with
the shaft pointing up. Slide the installation tool
(provided in the RSK) over the piston shaft with the wide
end down. Lubricate the new PIP ring, cup seal and the installation tool with silicon grease. With
the grooved side facing up, slide the PIP ring down the installation tool and onto the piston. Re-
peat this process for the cup
seal. Note that the grooved
side of the cup seal should be
facing down; i.e., the grooved
sides of the PIP ring and the
cup seal should be facing each
other. When finished with the
installation, remove the instal-
lation tool from the piston shaft.
2. To install the check valve
components, refer to Figure R-
3. Remove the old o-rings from
the poppet valves and valve
seats and install new o-rings from the RSK. Observe that the hole in the center of each valve seat
has a beveled edge on one side. Use your finger to press a valve seat into the bore for the reject
check valve assembly. The seat should be pressed all the way in, with the beveled side of the valve
facing outward (that is, against the end of your finger). Use the same technique to install the other
