DRAIN LINE FLOW CONTROL

The drain line flow control (DLFC) requires
assembly (Figure 11 Drain Line Flow Control).
1. Locate parts and a roll of plumber tape.
(plumber tape not included)
2. Wrap the tape over threads of the flow
control.
3. Screw the flow control and the 90° elbow
together. Hand tighten.
4. Place the ball into the flow control and
insert the assembly into the drain line
opening.
5. Push the assembly in and secure with the
drain line clip.

DRAIN LINE CONNECTION

NOTE: Standard commercial practices are
expressed here. Local codes may require
changes to the following suggestions. Check
with local authorities before installing a system.
1. The unit should be above and not more
than 20 feet (6.1 m) from the drain. Use an
appropriate adapter fitting to connect
1/2-inch (1.3 cm) plastic tubing to the drain
line connection of the control valve.
2. If the backwash flow rate exceeds 5 gpm
(22.7 Lpm) or if the unit is located 20-40
feet (6.1-12.2 m) from drain, use 3/4-inch
(1.9 cm) tubing. Use appropriate fittings to
connect the 3/4-inch tubing to the 3/4-inch
NPT drain connection on valve.
3. The drain line may be elevated up to 6 feet
(1.8 m) providing the run does not exceed
15 feet (4.6 m) and water pressure at the
softener is not less than 40 psi (2.76 bar).
Elevation can increase by 2 feet (61 cm)
for each additional 10 psi (.69 bar) of water
pressure at the drain connector.

Where the drain empties into an overhead sewer
line, a sink-type trap must be used. Secure the
end of the drain line to prevent it from moving.
NOTE: Waste connections or drain outlet shall
be designed and constructed to provide for
connection to the sanitary waste system through
an air-gap of 2 pipe diameters or 1 inch (22 mm)
whichever is larger.
WARNING: Never insert drain line directly
into a drain, sewer line, or trap (Figure
12 Drain Line Connection). Always allow
an air gap between the drain line and the
wastewater to prevent the possibility of
sewage being back-siphoned into the
softener.

Where the drain line is elevated but
empties into a drain below the level of the
control valve, form a 7-inch (18-cm) loop
at the far end of the line so that the bottom
of the loop is level with the drain line
connection. This will provide an adequate
siphon trap.
