Installation manual

backwash flowrate is greater than 7 gallons per minute, use a ¾
inch Water Softener drain line. Where the Water Softener drain
line is elevated but empties into a water drain below the level of
the Water Softener control valve, form a 7 inch loop at the
discharge end of pipe so that the bottom of the loop is level with
the drain connection of the Water Softener control valve. This will
provide an adequate anti-siphon trap. Where the drain empties
into an overhead sewer pipe, a sink-type trap must be used. Run
a drain tube to its discharge point in accordance with local
plumbing codes. Pay special attention to plumbing codes for air
gaps and anti-siphon devices.
8. WATER SOFTENER BRINE TANK CONNECTION
Install a 3/8 inch outside diameter polyethylene tubing from the
Water Softener refill elbow to the brine valve in the Water Softener
brine tank.
9. WATER SOFTENER OVERLOW DRAIN TUBING
CONNECTION
A Water Softener overflow drain tubing is recommended where
a Water Softener brine tank overflow could damage furnishings
or the building structure. Your Premium Water Softener will be
equipped with a brine tank safety float which greatly reduces
the chance of an accidental brine overflow. In the event of a
Water Softener malfunction, an overflow tubing connection will
direct the overflow to the drain instead of spilling on the floor
where it could cause considerable damage. This fitting should
be on the side of the Water Softener cabinet of brine tank. To
connect the Water Softener overflow fitting, locate a hole inside
of the brine tank. Insert the Water Softener overflow fitting into
the brine tank and tighten with plastic nut and gasket from the
inside. Attach a length of ½ inch inside diameter tubing (not
supplied) to fitting and run tubing to drain. Do not elevate the
Water Softener overflow tube higher than 3 inches below
bottom of overflow fitting. Do not “tie” this overflow tube into the
drain tube of the Water Softener control valve. Overflow tube
must be a direct, separate line from fitting to drain.
