E-Treat® Water Conditioning Anti-Scale System

NOTICE:
* Systems using OneFlow^® technology are effective at controlling lime-scale formation inside the plumbing system at influent hardness levels up to 30 grains per gallon (513 ppm CaCO3) of calcium carbonate. Due to variances in water chemistry, 30 grains per gallon is a recommended hardness maximum due to potential aesthetic issues related to soft scale residue formation outside of the plumbing system. Testing should be performed to determine proper application where hardness levels exceed 30 grains per gallon.

**Just as with conventional water softening media, OneFlow^® media needs to be protected from excess levels of certain metals that can easily coat the active surface, reducing its effectiveness over time. Public water supplies rarely, if ever, present a problem, but if the water supply is from a private well, confirm that the levels of iron (Fe) and manganese (Mn) are less than 0.3 ppm and 0.05 ppm, respectively.

WARNING:
***Pursuant to the EPA drinking water standards, the copper concentration permitted is up to 1.3 ppm. Typically originating from new copper plumbing, high levels of copper can foul OneFlow^® media. New Copper lines need to be passivated for a minimum of 4 weeks before placing the unit into service. For applications with copper concentrations greater than 1.3 ppm, please consult Watts Water Quality Technical Service. To further minimize any problem with excess copper, avoid applying excessive flux on the inner surfaces of the pipe and use a low-corrosivity water-soluble flux listed under the ASTM B813 standard.

NOTICE:
† OneFlow^® media does not reduce silica scaling. While silica tends to have a less significant effect on scale formation than other minerals, it 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 purposes.

†† All other contaminants must meet the requirements of the USEPA Safe Drinking Water Act. Specific Mineral and Metal MCL's, identified in Watts published Feed Water Chemistry Requirements, supersedes the USEPA SDWA. Water known to have heavy loads of dirt and debris may require pre-filtration prior to OneFlow^®.

OneFlow^® is an anti-scaling water treatment technology designed to protect plumbing components, pipes, fixtures, valves, fittings, hot water tanks, etc. from the negative effects typically caused by water hardness. OneFlow^® is an environmentally friendly alternative to water softening or any other treatment device designed to address scale. OneFlow^® prevents scale by transforming dissolved hardness minerals into harmless, inactive microscopic crystal particles. These crystals stay suspended in the water and have a greatly reduced ability to react negatively and form scale compared to untreated hard water.

OneFlow^® uses a specially designed media to convert the dissolved primary hardness mineral (calcium carbonate) into a relatively insoluble microscopic crystal so that it cannot cause harm downstream. A water softener, on the other hand, uses the principles of “ion exchange” to remove calcium and magnesium ions from water while replacing them with sodium ions. A water softener requires a control valve, backwashing, drain line, regeneration, and a brine tank to store salt while OneFlow^® requires nothing but an inlet and outlet connection.

No. OneFlow^® preserves the beneficial mineral content while preventing the possible negative scale formation associated with these minerals. By rendering the hardness minerals harmless while still keeping them present, you truly get the best of both worlds. Other treatment methods fall short. In a 2005 report on Nutrients in Drinking Water, the World Health Organization writes, “We conclude that hard water is good because it contains nutrients valuable in themselves…To minimize heart disease risk, the ideal water should contain sufficient calcium and magnesium to be moderately hard."

Water chemistry and peak flow rate are the guidelines used to assure optimal system performance. Most municipally treated (city) water falls well within our performance guidelines to ensure scale control results. However, there are chemistry limitations related to possible foulants and interference ions. Water known to contain visible dirt and debris must be strained using a wye-pattern strainer or equivalent (100 mesh) before OneFlow^® tank systems. More details are available on the product datasheets and IOMs. As with any water treatment technology, correct sizing of the system is important to ensure proper performance. However, OneFlow^® is more forgiving of flow variations and unplanned peaks than a conventional water softener.

Yes. Tank-based systems require media replacement every three years. Systems should be installed with this in mind. An isolation valve with a by-pass loop is recommended for most applications so the tank(s) can be taken off-line for media replacement. Filter housing based systems require cartridge replacement every year. Please refer to and follow the instructions in the Installation, Operation & Maintenance manual included with the OneFlow^® system.

Untreated well water may pose a limitation to OneFlow^® due to the unknown chemistry it often possesses. High hardness is never a problem for OneFlow^®, but with well water, hardness minerals are often accompanied by other contaminants with levels outside of our operating guidelines. Additionally, closed-loop systems that do not offer a “blow-down” or “flush valve” are not recommended because the micro-crystals need to exit the system.

For anyone who has ever installed a Water Pressure Reducing Valve or a Backflow Preventer, installation of a OneFlow^® system will be relatively easy. The E-Treat^® tank systems offer a 1" “plastic MPT” connection. Several OneFlow^® installation accessories are offered to accommodate most applications. OneFlow^® systems are compact allowing for easy installation when space is limited. OneFlow's^® light-weight makes it easy for the installer to transport with nothing more than a hand truck.

One of the great benefits of the OneFlow^® technology is the dramatically reduced maintenance requirements. Other than the planned media replacement, there is nothing else required. For tank systems, the media replacement is once every three years, and for filter housing systems, it's once every 2 years. That's it.

OneFlow^® is truly a “Green product” because it saves water and energy in the following ways:

1. Reduces Energy Consumption – OneFlow^® uses no electricity and reduces energy consumption by keeping heat transfer surfaces free of energy-robbing scale formation.
2. Reduces Chemical or Raw Material Consumption – OneFlow^® requires no chemical or significant ongoing consumable (salt, as an example).
3. Reduces Waste Water Discharge and Water Consumption – Because OneFlow^® does not discharge or require backwashing it meets both objectives.
4. Reduces Space Requirements – OneFlow^® systems use approximately 75% less floor space than water softeners.
5. Retains nature's minerals in the water. The beneficial minerals, calcium & magnesium, are completely retained.

1. E-Treat^® systems are warranted for domestic use in residential single-family dwelling applications excluding irrigation water treatment. The use of these systems in light commercial, commercial, or industrial applications will void their limited warranty.
2. The E-Treat^® system must be installed in applications with municipally supplied water adhering to EPA guidelines.
3. Any component failure must not result from abuse, fire, freezing or other acts of nature, violence, or improper installation.
4. Equipment must be installed and operated in compliance with the local plumbing codes and on an approved water supply.
5. Equipment is limited to use at water pressures and temperatures that do not exceed our published specifications.
6. Water supply must not exceed 3.0 PPM chlorine. For water supply exceeding 3.0 PPM chlorine, pretreatment is required. (Please contact your water treatment specialist.)
7. Information, including model number, serial number, and date of installation, must be provided for any claims pertaining to equipment in warranty.
8. Defective parts are subject to inspection by either Watts Regulator Company or any authorized representative before final commitment of warranty adjustment is made.
9. Watts Regulator Company reserves the right to make changes or substitutions in parts or equipment with material of equal quality or value and of then current production.
