Brine Piston
The Piston should have an O-Ring on the shaft side of the flange and a spring pressed onto a boss on
the other side. The O-Ring should be free of defects such as cuts or debris on the shaft side.
100237707
Housing
Just inside the entrance hole for the Brine Piston is a concave seat area that must be free of defects such
as nicks, indentations, or debris. This seat area ensures a leak-free seal for the static O Ring on the Brine
Piston. If any defects are detected by visual inspection, repair or replace as needed.

Flow Control
The Flow Button has two distinct and different sides. One is “flat”; the other is “concave.” The button
should be centered in the housing opening with the four locator “ribs” with the concave side facing the
Salt Monitor Probe.

Drain End Cap
The Drain End Cap seals the left opening on the Main Control Valve. The opening is sealed with an
O-Ring used as axial or “face” seal. The O-Ring sits in a groove in the End Cap. This groove must be free
of defects such as pits or scratches and also free of debris. When assembling the End Cap to the Main
Control Valve, care should be taken to make sure that the O-Ring stays in the groove in the End Cap. If
misaligned, the O-Ring can become pinched and leak.
Drain Line Flow
Control
The Drain Line Flow Control (DLFC) maintains a constant (plus or minus 10%) backwash flow rate at
varying pressures. Care should be taken when replacing DLFCs to ensure that the correct rate is being
used for a particular model. See
Specifications
. When assembling the flow control, ensure that the
rounded (radiused) side of the hole faces in toward the water flow. Available parts:

* Indicates the backwash flow rate in gpm.
100241821 Retainer
The Retainer holds the backwash Flow Control in place. One side is smooth and the other has a groove
for a screwdriver. When assembling the retainer to the Drain End Cap, the retainer should be screwed in
until it stops. If the retainer is not fully engaged, the Flow Control may not function properly.
