Watts E-Treat® Water Conditioning Systems

Using No-Salt Technology 

Good for the environment. Good for the planet. Good for you! 

Conventional water softeners are generally considered the most effective and practical way to reduce water hardness and prevent scale formation in pipes and plumbing fixtures. Water softeners, however, require salt to regenerate, and they must be backwashed periodically to rinse and refresh the ion exchange resin. Brine water discharge and the need to conserve water have challenged this conventional technology, and new methods to provide scale-free water are being considered. 

Introducing The Environmentally Friendly Solution
To Water Quality Improvement Problems! 

With E-Treat® water conditioning systems, there’s no salt, no backwash, no scale, no chlorine and no electricity!

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 inner tank where treatment for scale prevention is provided using our highly effective, 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 E-Treat®, 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 E-Treat® anti-scale systems virtually eliminate 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. 



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 drink- ing 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".

Media And Carbon Replacement 

E-Treat® water conditioning systems with 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. A dome hole is provided for this extraction. 

Our trained water quality improvement dealer in your area can complete the media and carbon replacement
