Maintaining the Drain Line
The drain line discharges and brine during the
regeneration cycle. Typically, the line drains into your
floor drain or laundry tube. The installer should plumb
the drain line according to local codes, leaving a one
or two inch air gap between the end of the drain line
and the drain opening. Figure 5.
Be sure that the drain line remains unrestricted so the
regeneration water and brine can flow freely to the
drain. Do not set objects on the drain line that could
crimp the line and restrict flow.

Caution
Do not overtighten the plastic cap. Seat the cap
lightly into position. Overtightening can cause
breakage of the plastic cap, which may not be
evident immediately.
