4.0 EQUIPMENT SPECIFICATIONS
4.1 SOFTENER TANK(S)
Each system shall include _____ tank(s). Each softener tank shall be _____ inches in diameter. The sideshell
height shall be _____ inches, sufficient to allow for proper freeboard space above the resin bed for adequate
expansion of the resin during backwashing.
4.1.0 Tank Construction
Tank(s) shall be manufactured of polyester reinforced by a continuous roving glass filament overwrap. The top
opening will be 4”-8 UN threaded and the tank bottom will be supported on a molded structural base.
4.2 INTERNAL DISTRIBUTION
4.2.1 The upper distribution system shall be of the single point diffuser type to dispense water laterally to avoid
channeling within the resin bed.
4.2.2 The lower distribution system shall be of the single point distributor type, constructed of PVC pipe and a fine
slotted strainer to provide even flow distribution through the resin bed. The distribution system shall be
embedded in a subfill of washed inorganic material to support the resin bed.
4.3 MAIN OPERATING VALVE
The main operating valve shall be of a top mount design constructed of all brass and sized with 2 inch NPTI
inlet and outlet connections.
The main operating valve will be of the motor driven, mechanically activated design with four (4) positions to
accomplish the regeneration steps of backwash, brine draw/rinse and fast rinse/brine refill, in addition to the
service position.
The main operating valve shall incorporate self adjusting flow regulators to control the rate of flow and prevent
resin loss during backwash regardless of system pressure fluctuations between 30 and 120 psi.
The main operating valve will be fitted with a fixed orifice eductor.
¨ (Single units only – hard water bypass)
The unit shall be supplied so that the valve will allow automatic bypass of untreated water during regeneration.
The bypass shall be integral to the main operating valve body and be capable of being easily modified to
prevent hard water bypass.
¨ (Single units only – NO hard water bypass)
