Drain End Cap
1
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
1
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. Refer to
specifications. When assembling the flow control, ensure that
the rounded (radiused) side of the hole faces in toward the
water flow.

Retainer
1
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.
