CAUTION: Never insert a drain line into a drain, sewer line,
or trap. Always allow an air gap of 1-1/2" or
twice the pipe diameter, whichever is greater,
between the drain line and the wastewater to
prevent the possibility of sewage being back-
siphoned into the conditioner.
9. BRINE TANK CONNECTION: Install the 3/8" O.D. polyethylene tube from the Refill Elbow to the
Brine Valve in the brine tank.
10. OVERFLOW LINE CONNECTION: An overflow drain line is recommended where a brine
overflow could damage furnishings or the building structure. Your softener is equipped with a brine
tank safety float which greatly reduces the chance of an accidental brine overflow. In the event of a
malfunction, however, an overflow line connection will direct the “overflow” to the drain instead of
spilling on the floor where it could cause considerable damage. This fitting is an elbow on the side
of the brine tank. Attach a length of 1/2" I.D. tubing to fitting and run to drain. Do not elevate
overflow line higher than 3" below bottom of overflow fitting. Do not “tie” this tube into the drain
line of the control valve. Overflow line must be a direct, separate line from overflow fitting to drain,
sewer, or tub. Allow an air gap as per the drain line instructions.
