Introduction
The Watts OneFlow
®
Anti-Scale System provides protection from
scale formation on internal plumbing surfaces. These smart and
connected systems monitor their own service schedule as well
as water usage. Automatic alerts are sent to the user by email
or text notifying when media replacement is necessary. The
OneFlow system can 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 water using device
that requires protection from hard water.
OneFlow prevents scale by transforming the normal dissolved
hardness minerals into harmless, inactive microscopic crystal
particles. These crystals stay suspended in the water and have
a greatly reduced ability to react and attach to surfaces like
dissolved hardness does. Therefore the problem of internal
buildup of scale in pipes, water heaters and on fixtures and
glass is greatly reduced.
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 successful
residential and commercial installations. OneFlow is the one
water treatment device that effectively provides scale protection and
is a great salt-free alternative to water softening (ion exchange)
or scale sequestering chemicals. Laundry and warewashing
chemistry will likewise require adjustments.
