Salt Line Connection
The salt line from the brine tube connects to the valve. Make
certain the connections are hand tightened. Be sure that the
salt line is secure and free from air leaks. Even a small leak
may cause the salt line to drain out, and the softener will not
draw salt from the tank. This may also introduce air into the
valve causing problems with valve operation.
To install the brine line:
1. Inside the salt tank, remove the cap from the large cylinder
to gain access to the connection.
2. Be sure the brass insert is in the end of the brine tubing.
Insert the tubing through the opening in the tank.
3. Push the tubing into the plastic nut. Slowly unscrew the nut
until the tubing moves into the connection. The tubing will
hit bottom.
NOTE: Once the tubing has been pushed into the nut, it cannot
be pulled out. The nut will need to be removed. See
Figure 13 for correct assembly.
4. Hand tighten the nut until the connection is tight.
