No need for costly bypass plumbing. • Compatible with all on-site and community wastewater treatment systems. • Not subject to water softener restrictions and “bans”. • OneFlow® treated water has no added sodium, is safe to drink and is well suited for use in food and beverage preparation.Equipment SpecificationsWatts OneFlow® systems are complete, self-contained, loaded with media and ready to use. A simple inlet and outlet connection is all that is required for installation. Please review below all operating pressures, temperatures and water chemistry limitations to ensure compatibility with your system.About Watts OneFlow® Anti-Scale SystemsThe OneFlow® Anti-Scale System provides protection from scale formation on internal 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 hardness minerals into harmless, inactive microscopic 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. 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 antiscalants or sequestrants). It is a scale prevention device with proven third party laboratory test data and years of successful residential and commercial applications. 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.Standard 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 control valve • Uses environmentally friendly technology by using no salt or other chemicals to constantly add, no electricity and no wastewater • 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 softeners are banned or restricted • For high-flow applications, install multiple tanks in parallel • OneFlow® does not remove minerals or add sodium to the water supply • OneFlow can be installed as pre-treatment to commercial reverse osmosis systemsFeed Water Chemistry Requirements• pH range: 6.5-8.5 • Hardness (maximum) 75 grains (1282 ppm CaCO3) • Water Pressure 15 psi to 100 psi • Temperature 40° F to 100° F • Free Chlorine
