OneFlow® Anti-Scale System


3/4 in. (20mm)


The OneFlow® Anti-Scale System provides protection from
scale formation on internal and external plumbing surfaces.
The OneFlow® system is a single cartridge-based system
that must be installed on a cold water line prior to a waterheating
device (water heater or tankless water heater) for
single tankless heaters.

OneFlow® prevents scale by transforming dissolved hardness
minerals into harmless, inactive microscopic crystal particles.
These crystals stay suspended in the water and are passed
to drain. The system requires very little maintenance, no backwashing,
no salt and no electricity. Typical hardness problems,
especially build-up of scale in heating elements, pipes, water
heaters, boilers and on fixtures are no longer a concern.

OneFlow® is not a water softener. It does not add chemicals.
It is a scale prevention device with proven third party laboratory
test data and years of successful commercial, residential
and food service applications. OneFlow® is The Intelligent
Scale Solution™ and is a great alternative to water softening (ion
exchange) or scale sequestering devices.
