Pentair Whole House Water Softening System
Operating Pressure: 20 -120 psi (138 kPa - 828 kPa), Operating Temperature: 40 - 100° F (4.4° C - 38° C) Acceptable Salt
Type: Sodium Chloride – Pellet or solar salt water softeners
All Systems tested at 35psi +/- 5 psi, pH of 7.5 +/- 0.5, Capacity Testing Flow Rate = 50% of the rated service flow rate
for the various size systems.
These water softener systems have been tested by WQA and conform to NSF/ANSI 44
for specific performance claims as verified and substantiated by test data. The rated
salt efficiencies above were also determined in accordance with NSF/ANSI 44 and
are only valid at the salt dosage referenced above. An efficiency rated water softener
is a demand initiated regeneration (DIR) softener which also complies with specific
performance specifications intended to minimize the amount of regenerant brine and
water used in its operation. Efficiency rated water softeners shall have a rated salt
efficiency of not less that 3350 grains of total hardness exchanged per pound of salt
(based on NaCl equivalency) (477 grams of total hardness exchanged per kilogram of
salt), and shall not deliver more salt than its listed rating. The rated efficiency of the
water softener, the salt dosage at that efficiency, the capacity at that salt dosage and
that of the efficiency is only valid at the stated salt dosage. Efficiency is measured by a
laboratory test described in NSF/ANSI 44. The test represents the maximum possible
efficiency the system can achieve. Operational efficiency is the actual efficiency
achieved after the system has been installed. It is typically less than the stated
efficiency due to individual application factors including water hardness, water usage,
and other contaminants that reduce the water softener’s capacity. These systems are
not intended to be used for treating water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after the system.
