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 ½-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 ¾-inch (1.9 cm) tubing. Use appropriate
fittings to connect the ¾-inch tubing to the ¾-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 conditioner 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.
4. 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.
Tie or wire the hose in place at the drain point. Also
provide an air gap of at least 1-1/2 inch between the
end of the hose and the drain point.
5. Where the drain empties into an overhead sewer line,
a sink-type trap must be used.
6. Secure the end of the drain line to prevent it from
moving.

WARNING: Never insert drain line directly
into a drain, sewer line or trap (Figure 11).
Always allow an air gap between the drain
line and the wastewater to prevent the
possibility of sewage being back-siphoned
into the conditioner.

Regenerant Line Connections

The regenerant line from the tank connects to the valve.
Make the connections and hand tighten. Be sure that the
regenerant line is secure and free from air leaks. Even a
small leak may cause the regenerant line to drain out, and
the conditioner will not draw regenerant from the tank.
This may also introduce air into the valve causing
problems with valve operation.
Ensure that pipe sealant (Teflon

Regenerant Line Connection
To install the line:
1. Insert one end of the tubing into the elbow on the
valve.
2. Hand tighten the nut until tight.
3. Inside the salt tank, remove the cap from the large
cylinder to gain access to the connection.
4. Be sure the brass insert is in the end of the brine
tubing. Insert the tubing through the opening in the
tank.
5. Push the tubing into the plastic nut. Slowly unscrew
the nut until the tubing moves into the connection.
The tubing will hit bottom.
