OneFlow
® Residential Anti-Scale Systems provide a home
with protection from internal hardness related scale formation
on plumbing surfaces. Water using appliances and plumbing
fixtures also enjoy a longer lifespan because hardness scale
build up on internal parts no longer occurs. These systems
are specifically designed for residential applications. OneFlow ®
Residential systems should be installed at the point-of-entry to
a home to treat both the hot and the cold water.
OneFlow
® Residential systems prevent scale by transforming
dissolved hardness minerals into harmless, inactive microscop-
ic crystal particles. These crystals stay suspended in the water
and are passed to drain, thereby having a greatly reduced
ability to react negatively like dissolved hardness does. These
systems require very little maintenance, no backwashing, no
salt, and no electricity. Typical hardness problems, especially
build-up of scale in pipes, water heaters, boilers, fixtures, and
appliances are no longer a concern.
OneFlow
® Residential systems are not water softeners or
chemical additives (like anti-scalants or sequestrants). They are
scale prevention devices with proven third party laboratory test
data and years of successful applications. OneFlow ® Residential
systems are the one water treatment device that effectively pro-
vides scale protection in the home and are a great alternative to
water softening (ion exchange) or scale sequestering chemicals.

Features
• Chemical free scale prevention and protection – converts hard-
ness minerals to harmless, inactive microscopic crystals mak-
ing OneFlow ® an effective alternative technology to a water
softener for the prevention of scale due to water hardness
• Virtually maintenance free – No salt bags or other chemicals
to constantly add
• No control valve, no electricity and no wastewater
• Uses environmentally friendly “green” technology
• Improves efficiency of all water using appliances – both hot*
and cold
• Simple sizing & installation
• Perfect system for towns or communities where water soften-
ers are banned or restricted
• OneFlow ® - Residential systems do not remove minerals or
add sodium to the water supply
• OneFlow ® - Residential systems can be installed as a pre-
treatment to reverse osmosis (OneFlow ® should be the last
stage in treatment unless a point-of-use system is being used
downstream.)
• Systems include a bypass valve for a simplified installation
OFRES
*Always install OneFlow ® Residential systems before the water heat
ing device.
Note: Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after the
system.
