Before talking about the Aquasana EQ-SS20 Simplysoft salt-free water softener…

Imagine these situations:

You are thirsty, feeling like some fresh, cold water. 

You’re wanting to take a nice and refreshing shower.

You are doing your dishes.

Or just need to get some clothes neatly washed.

What do all those actions have in common? They require tap water. Now, most of us have access to drinkable water. Your water may not be as good as you think, even if it’s safe to drink and use every day. Usually, water is chlorinated during its treatment process, which reduces the number of bacteria in the water. However, most regular tap water contains minerals, and chlorine treatments are harmful if not done correctly. This impacts the taste of water and affects performance during normal household tasks.

One of the best ways to improve tap water is by installing a water softener. The Aquasana EQ-SS20 water softener is a great salt-free water softener

Elevated Cooking Experience

You want cleaner cooking, improved tastes, a much more robust flavor, and quicker boiling time. Altogether, the Aquasana EQ-SS20 Simplysoft Salt-Free Water Softener creates a better kitchen experience. In addition, water softeners play a significant role in professional kitchens, where clean water is an essential ingredient.

Better Taste

EQ-SS20 reduces up to 97% of chlorine in regular tap water, as well as cleans water of many toxic metals like lead and mercury. The tap water that we drink is full of industrial solvents, pesticides, herbicides, or other organic chemicals that change taste. Using a water softener reduces these, too, leaving the water cleaner and tastier.

Easier Breathing

Because of the warmth of the water when showering, volatile organic chemicals (VOCs) and chlorine in the tap water evaporate, polluting the air.

Installing the Simplysoft EQ-SS20 helps remove these toxic elements, leaving both the water and the air cleaner than it was before. In turn, this improves the health of your skin, hair, and body.

Cleaner House and Pipeline

Contaminants and particles produce dust and dirt in the house, especially inside plumping and pipes. The EQ-SS20 not only cleans your living space but reduces the rate of corrosion in your pipes, making your plumbing last much longer.

This may sound great, but the price is always a factor. Most other water softeners are a hefty initial expense and have costly maintenance fees. But the Aquasana Simplysoft EQ-SS20 is almost entirely maintenance-free, and the initial expense is reasonable and affordable.

Simplysoft Specifications

Slow Phos technology

Innovative SLOW PHOS salt-free water-softening technology is used by Simplysoft to clean the water and shield the pipes from corrosion without the usage of additional salts and minerals. SLOW PHOS technology reduces the water’s atomic connection by modifying the ionic charge in hard mineral crystals. By doing so, the mineral crystals won’t consolidate, preventing them from creating different calcium, magnesium, or barium-based compounds.

So how does that work? SLOW PHOS technology is a slowly soluble source of polyphosphate, available in thin, glassy beads. SLOW PHOS technology products are engineered, as their name suggests, to dissolve harmful elements at a controlled concentration to avoid scale formation and corrosion.

Unlike other salt-based softeners, Aquasana softener technology will not demineralize the water. You will not do anything right by applying excessive quantities of sodium to our community water supply. That may lead to an adverse impact on the ecosystem.

An additional feature of this softener is UV Filtration technology, which frees the water you use from 99% of bacteria and viruses.

Installation Process

First, make sure to read all the material given by the manufacturer and retailer about the installation. The operating range of the pump is between 20 psi and 100 psi. It is essential that the pressure should not exceed 100 psi. Just as important as pressure, the temperature must be between 40 and 90 degrees Fahrenheit. Keep the entire frame facing up before you start installing. If it is placed upside down, you’ll have to disassemble and start over.

Step by Step Guide

Turn off the water in the connecting system.

Using the components from the water softener’s supplier, install and adjust the central unit to the central water supply. Follow the installation diagram included with the product.

The bracket should be used to keep the central unit firmly braced to the main supply.

Once you make sure everything holds tight, let the water flow through the system. If there are no leaking spots near the softener, flush through for ten minutes.

This technology system is certified under ANSI/NSF standards, which stands for both 42 Drinking Water Treatment Units and 60 Drinking Water Treatment Chemicals. Put simply, it can be used in water systems that have a concentration that does not exceed ten ppm. (The typical rate of dissolution is from 90 to 180 days).

The EQ-SS20 is affordable, usually in the lower part of the cost range in the industry, depending on the supplier. Considering its remarkable capacity – and comparing to other water softener systems – it strikes a balance between the price and its sustainability. It pays every cent with 50000 gallons of total power and a rated flow of 7 gallons per minute.

The sturdy but lightweight frame allows for easier installation, use, and maintenance, and is built to last. Remember to change the main cartridge every six months.
