The system makes a good supply of drinking water each day.
How much it will make depends primarily on these things…

For water with hardness greater than 10 grains (at 6.9 pH) the use of a
softener is recommended. Failure to install a water softener will reduce
the life of the Reverse Osmosis membrane. See chart for additional
information on the possible need for a water softener.
a. Tested according to NSF/ANSI Standard 58. Source water test parameters are 50 psig, 77°F,
pH of 7.5 ± 0.5, and 750 ± 40 ppm total dissolved solids.
b. Removed by the Reverse Osmosis prefilter. REGULAR MAINTENANCE IS REQUIRED. Chlorine will
destroy the Reverse Osmosis membrane.
c. If house water pressure is over 125 psi, install a pressure reducing valve in the water supply line.
If house water pressure is under 40 psi, install a Reverse Osmosis booster pump (contact your
local plumbing supply company).
d. Theoretical tank capacity. When tested according to NSF/ANSI Standard 58 at 50 psig inlet
pressure, tank capacity is 2.3 gallons.
e. Efficiency rating means the percentage of the influent water to the system that is available
to the user as Reverse Osmosis treated water under operating conditions that approximate
typical daily usage.
f. Recovery rating means the percentage of influent water to the membrane portion of the system
that is available to the user as Reverse Osmosis treated water when the system is operated without
a storage tank or when the storage tank is bypassed.
