OneFlow Benefits
®
• Smart and connected elapsed time monitor - Sends automatic
alerts via email and text when media replacement is due
• Monitors and displays water usage and remaining media life
• 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 and generates no waste water
• 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
• Safe for landscaping and lawn watering - No need for costly
bypass plumbing
• Compatible with all on-site and community wastewater
treatment systems
• Perfect system for towns or communities where water
softeners are banned or restricted
• OneFlow does not remove minerals or add sodium to the
water supply.
• OneFlow can be installed as pre-treatment to commercial
reverse osmosis systems (contact your Watts Representative
for further details).
* For high-flow applications, contact your Watts Representative
for details on larger, multi-tank systems plumbed in parallel
that can meet high flow applications from 100 gpm to and
above 1000 gpm.
** For hot water applications where feed water temperature is
100°F - 140°F (38° - 60°C), please consult ES-OneFlow-HotWater.
