Description
OneFlow® Residential Anti-Scale Systems provide a home with protection from internal hardness related scale formation on plumbing surfaces. Water using appliances and plumbing fixtures also enjoy a longer lifespan because hardness scale build up on internal parts no longer occurs. These systems are specifically designed for residential applications. OneFlow® Residential systems should be installed at the point-of-entry to a home to treat both the hot and the cold water.

OneFlow® Residential systems prevent 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. These systems require very little maintenance, no backwashing, no salt, and no electricity. Typical hardness problems, especially build-up of scale in pipes, water heaters, boilers, fixtures, and appliances are no longer a concern.

OneFlow® Residential systems are not water softeners or chemical additives (like anti-scalants or sequestrants). They are scale prevention devices with proven third party laboratory test data and years of successful applications. OneFlow® Residential systems are the one water treatment device that effectively provides scale protection in the home and are a great alternative to water softening (ion exchange) or scale sequestering chemicals.

Features
• Chemical free scale prevention and protection – converts hardness minerals to harmless, inactive microscopic crystals
• OneFlow® an effective alternative technology to a water softener for the prevention of scale due to water hardness
• Virtually maintenance free – No salt bags or other chemicals to constantly add
• No control valve, no electricity and no wastewater
• Uses environmentally friendly “green” technology
• Improves efficiency of all water using appliances – both hot* and cold
• Simple sizing & installation
• Perfect system for towns or communities where water softeners are banned or restricted
• OneFlow® - Residential systems do not remove minerals or add sodium to the water supply
• OneFlow® - Residential systems can be installed as a pretreatment to reverse osmosis (OneFlow® should be the last stage in treatment unless a point-of-use system is being used downstream.)
• Systems include a bypass valve for a simplified installation
• Long Lasting media needs no regeneration—replace on average once every 3 years

Feed Water Chemistry Requirements
• High levels of Copper will foul OneFlow media and typically originates from new Copper plumbing. Wait a minimum of 4 weeks before placing system in operation. Avoid applying excess flux on the inner surfaces of the pipe and to use a low-corrosivity water soluble flux listed under the ASTM B813 standard.

• pH range: 6.5-8.5
• Hardness (maximum) 25 grains (427 ppm CaCO3)
• Water Pressure 15 psi to 100 psi
• Temperature 40° F to 110° F
• Free Chlorine <2 ppm
• Iron (maximum) 0.3 ppm
• Manganese (maximum) 0.05 ppm
• Copper 1.3 ppm
• Silca (maximum) 20 ppm**
• Oil & H2S Must be Removed Prior to OneFlow
• Polyphosphates Must be Removed Prior to OneFlow

OneFlow® Application Practices
Systems using OneFlow® technology prevent hard water scale formation inside the plumbing system at influent hardness levels of 25 grains per gallon of calcium carbonate and less. Due to variances in water chemistry, certain aesthetic conditions external of the plumbing system may not be attained.OneFlow® is designed for the treatment of potable water that meets the requirements of the current USEPA Safe Drinking Water Act. The addition of soaps, chemicals or cleaners, before or after the OneFlow treatment, may reverse its anti-scale treatment effects and/or create water with heavy residue or spotting potential. Any adverse conditions caused by the addition of soaps, chemicals or cleaners is the sole responsibility of the end user.New copper lines need to passivated before placing unit into service. Copper usually originates from new copper plumbing upstream of the OneFlow® system. All new copper plumbing before the system should be allowed to passivate by operating under normal conditions for a period of four weeks prior to starting up the system. This will allow the copper surfaces to be fully flushed and develop a natural protective surface. To further minimize any problems with excess copper, avoid applying excess flux on the inner surfaces of the pipe and use a low-corrosivity, water-soluble flux listed under the ASTM B813 standard. OneFlow® is not designed for use on closed loop systems.

Product Notices, Use & Warnings
• OneFlow media does not reduce silica scaling. Silica can act as a binder that makes water spots and scale residue outside the plumbing system difficult to remove. This 20 ppm limitation is for aesthetic purpose.
• These systems prevent hardness related scale formation inside the plumbing system of the home at influent hardness levels of 25 grains per gallon of calcium carbonate and less. Due to variances in water chemistry certain aesthetic conditions external of the plumbing system may not be attained. Water known to have heavy loads of dirt and debris should be prefiltered.
• Copper lines need to be passivized for a minimum of 4 weeks before placing unit into service
• Not for use on closed loop systems
• Maximum service flow rate is for intermittent use only and is not to be interpreted as continuous service flow rate capability.
• These systems are designed to treat the domestic water used in a single family dwelling
• Exceeding maximum flow can reduce effectiveness and void warrany

Standards
Independent scientific testing has confirmed Template Assisted Crystallization (TAC) technology provides scale reduction of over 95+%. Testing was conducted under protocol based on DVGW W512 test to access control of scale formation
