Watts E-Treat® No-Salt Water Conditioning Systems


Here’s how it works:

Step #1 (Main Tank)
Water enters the system and flows down through a two cubic foot bed of coconut shell activated carbon. This initial water treatment process improves water quality by reducing bad tastes, foul odors, chlorine and organic substances through adsorption.

Step #2 (Inner Tank & Contact Chamber)
During this process, water flows upward through the rise tube into the inner tank where treatment for scale prevention is provided using our highly effective, ScaleNet™ anti-scale media. This unique material transforms calcium ions into Calcium crystals, which are stable and cannot attach to pipes, surfaces, hardware or heat exchanger components. The crystals are so small they are easily rinsed away by the water flow!

With ScaleNet™, there is no scale on plumbing fixtures, no costly repairs to hot water heaters due to scale, no salt, no brine tank and no electrical control valve. The installation is easy because only a simple “in and out” valve is required.

* Performance testing proves ScaleNet™ anti-scale media virtually eliminates new scale formation and aids in the removal of existing scale. Results may vary, however, and performance is based on water hardness levels, flow rate and other factors.


E-Treat® Water Conditioning Systems

Calcium scale in pipes and plumbing equipment results in high energy costs and may lead to expensive repairs to appliances, such as hot water heaters, ice machines, coffee makers and dishwashers. Scale can also be a source for bacteria to grow, which may become a health concern in drinking water applications.

On the other hand, Calcium is important to human health, and supplements are recommended if Calcium is reduced or totally void in one’s diet.

E-Treat™ water conditioning systems are typically installed where water enters the house for whole house water treatment. Pipe connections are 1″.

ScaleNet™ Media And Carbon Replacement
E-Treat™ water conditioning systems with ScaleNet™ anti-scale media are designed to provide whole house water conditioning for up to five years, based on hardness and chlorine levels before the anti-scale media must be replaced.

We recommend replacement of the activated carbon every two years, for optimum performance.

NOTE: Do not use where water is microbiologically unsafe or with water of unknown quality without adequate disinfection before or after the unit. System must be maintained according to manufacturer’s instructions. Pre-treatment for sediment, Iron, Hydrogen Sulfide, Manganese, hydrocarbons and copper may be required depending on conditions. Install systems in new homes with copper pipe after one month of water use.
