Systems
Connection Size: 3" (80 mm)
Flow Rates: Up to 280 gpm (1059 lpm)
Watts Pure Water Series PWS30 and PWS30-2 water soften-
ing systems are high efficient conventional cation exchange
type water softeners. They are suitable for commercial applica-
tions ranging from 300,000 to 1,050,000 grains of hardness
removal per tank and flow rates up to 280 gallons per minute
(1059 lpm). Where continuous softened water is required
PWS30-2 duplex alternating systems can be specified for unin-
terrupted service. Regeneration is meter demand initiated. All
cycles of regeneration are fully automatic and do not require
manual actuation.
Watts Pure Water Series PWS30 and PWS30-2 water soften-
ers are designed for point of use or point of entry applications
where the benefits of softened water are required. These sys-
tems exchange scale-forming calcium and magnesium ions
with non scale-forming sodium ions to create soft water for
a variety of applications. Steam boiler make up water, water
heater pretreatment, reverse osmosis pretreatment, cooling
tower make up water, sterilizer make up water, washing, and
process water are all common applications for the Watts Pure
Water Series PWS30 water softeners.
Softened water provides a wide variety of benefits from not
introducing scale into pipes, valves, water heating equipment,
heat exchangers, and cooling towers to reducing mineral build
up in areas that see excessive splashing such as food prepara-
tion counters and sink areas. Softened water also conserves
soaps and cleaning agents by eliminating the formation of soap
curd, so your cleaners can work on cleaning – not reacting
with the hardness in your water.

Specifications
A Watts Pure Water Series PWS30 water softening system
shall be installed on the building’s main water line just after
it enters the building. The installation point shall be after any
backflow prevention or pressure regulating valves. Other instal-
lation options are to install a system just before the water
heater or other types of equipment needing the protection of
softened water. In installations where dedicated cold water
make up to a water heater is the installation point, a backflow
preventer and a thermal expansion tank must be installed as
well. The system shall be installed with a bypass valve to allow
for the shut down and removal of the unit without interrupting
the water supply to the building.
The water softener shall be a down flow regenerated, metered
demand, sodium cycle cation exchange type system with all
components necessary for proper operation. Electrical require-
ments are 120 volt 60 hertz. A local drain is required to accept
drain water from the system. The feed water pressure must not
fall below 25psi or exceed 125psi. Water temperature must not
fall below 34°F or exceed 110°F (1°C - 43°C).
The system shall provide softened water measuring less than
one grain per gallon of hardness as Calcium Carbonate when
operated within the manufacturers operational specifications.
