The OneFlow
® Anti-Scale System provides protection from
scale formation on internal and external plumbing surfaces.
The OneFlow ® system may be installed at the point-of-entry
to a building to treat both hot* and cold water, or it can be
located directly before a water heater, boiler, or other hot
water-using device that requires protection from the ill effects
of hard water.
OneFlow
® prevents scale by transforming dissolved hard-
ness minerals into harmless, inactive microscopic crystal
particles, as water travels through the media filled tank. These
precipitated micro-crystals stay suspended in the water and
are passed to drain, thereby having a greatly reduced ability
to react negatively like dissolved hardness does. The system
requires very little maintenance, no backwashing, no salt, and
no electricity. Typical hardness problems, especially build-up
of scale in pipes, water heaters, boilers and on fixtures are no
longer a concern.
OneFlow
® is not a water softener or a chemical additive (like
anti-scalants or sequestrants). It is a scale prevention device
with proven third party laboratory test data and years of suc-
cessful residential and commercial applications. OneFlow ® is
the one water treatment device that effectively provides scale
protection and is a great alternative to water softening (ion
exchange) or scale sequestering chemicals.

Features
• Chemical-free scale prevention and protection – converts
hardness minerals to harmless, inactive microscopic crystals
making 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 – all you need to know is pipe size
and the peak flow rate
• Perfect system for towns or communities where water soften-
ers are banned or restricted
• Manifold assemblies for easy installation of multi-tank, high-
flow applications (Can be operated in parallel for high flow
applications.)
• OneFlow ® does not remove minerals or add sodium to the
water supply
• OneFlow ® can be installed as pre-treatment to reverse osmo-
sis (OneFlow ® should be the last stage in treatment unless a
point-of-use system is being used down stream.)
