How does it work?
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.
