INSTALLATION
Connect Drain Line
Gravity Overow Elbow
The overow line drains away excess
water should the cabinet overll or the
water softener malfunction. The overow
opening in the brine cabinet is not threaded.
Push and turn the overow elbow to tighten
into the brine cabinet. Ensure the overow
elbow is in the down position.
Connect 1/2” (1.27 cm) I.D. tubing (size cannot
be reduced) between the overow tting and
a oor drain, laundry tub, or other suitable
waste receptacle.
The drain line carries away backwash
water as part of the regeneration cycle.
1. Using PTFE tape or plumber’s putty,
screw threaded drain tting into
drain end cap.
2. Connect drain line to drain end cap
with a minimum 1/2” (1.27 cm) I.D.
tubing (supplied). This size cannot be
reduced.
3. Route drain line to a oor drain,
laundry tub, or other suitable waste
receptacle. Maintain a minimum 2”
(5 cm) air gap between drain line and
ood level rim of waste receptacle to
prevent back siphoning. This drain line
should be the shortest distance to the
suitable drain.
4. Drain line may be elevated up to
8’ (2.4 m) from the discharge on the
water softener if water pressure in
your system is 40 psi (2.8 bar) or more.
5. If drain line is 25 feet (7.6 m) or longer,
increase drain line to 3/4” I.D. The end
of drain line must be equal to or lower
in height than the control valve.

NOTICE: Keep the drain line from being kinked,
crimped, or restricted in any way.
NOTICE: This tubing is not supplied with the
water softener. Ensure the overow line ends
at a drain that is at least 3” (8 cm) lower than
the bottom of the overow tting. Maintain
a minimum 2” (5 cm) air gap between the
overow line and the ood level rim of the
waste receptor to prevent back-siphoning.
The gravity line cannot be run overhead.
NOTICE: Drain line may require a hose clamp to
hold drain line in place.
