Factors to Consider When Buying the Best Water Descalers

Before buying a water descaler for your home, it is essential to educate yourself on the crucial shopping consideration to keep in mind;

1. The capacity of the water descaler

Water hardness or softness is commonly measured using grains per gallon (gpg), where one grain is equal to 0.002 ounces of calcium carbonate dissolved in 1-gallon 0f water. Water with 0-3 gpg is usually considered soft water, and 3.5-7 gpg is moderate water, while water with more than 7.5 gpg is considered hard water.

A water descaler's capacity is the measurement of grains per week that the unit can handle before replenishing. Small water descalers come with weekly grain capacities from 16,000 to 32,000, while large water descalers have grain capacities from 40,000 to 64,000.

However, bear in mind that the harder your water is, the more grains the system will handle. A 54,000-grain system would operate differently with 3-gpg water running through it than if it had 10-gpg water to manage.

2. Bypass valve

Valves usually control the flow of water through a pipe, closing or opening when necessary. Bypass valves also work in the same way as standard valves; however, their purpose when used with a water descaler is to divert the flow of water away from the system, allowing you to access the hard water running into the home.

If you have just bought a descaler, this feature may seem useless. Nonetheless, a bypass valve can save you time as well as money by preventing your water descaler from using excess salt or energy to soften the water used for washing the deck or watering the lawn. 

Therefore, you can use the bypass valve to divert the water flow around the descaler and back into your pipes. Once this action is complete, close the bypass valve and restore water flow through your descaler.

3. Available area for the water descalers

Dual tank, salt-free, and even some salt-based water softeners may require a lot of space. Therefore, you need to measure the area where the water descaler will be installed and compare it to the manufacturer's installation specifications, that is if you are concerned about space.

Most of the salt-free descalers on the market are smaller than salt-based water softeners. Besides, they are installed directly on the waterline and hang down 1 or 2 feet, depending on the brand.

Magnetic water descalers take up the least amount of space, and you can install them without cutting into your plumbing. You can mount these small water softeners directly on the pipe and not interfere with your floor space. These models are the ideal option to save space in smaller houses.

4. Ion exchange capacity

When people mention residential water descalers, they usually refer to traditional salt-based softening that relies on an ion exchange process to replace hard minerals (calcium and magnesium) in the water with sodium or potassium ions. If you are one of the people who have problems with extra salt in their diet, you need to consider a salt-free water softener.

Overall, the ion exchange process is considered the industry standard and is still the preferred choice for most homeowners due to their unique performance. Nevertheless, salt-free softeners are becoming more popular with increasing effectiveness.

5. The Cost of the Water Softeners

The cost of a water softener depends on its size, brand, type, and additional features. You can spend anywhere between a few hundred and a few thousand dollars for a standard ion exchange system. However, water conditioners are slightly cheaper.

When considering the cost, remember to take into account expenses for installation and operation. Furthermore, ensure the water softener can pay for itself down the road in that, even after 15 years, your home appliances and pipes are still in good condition.

6. Water descaler regeneration methods

There are three methods for how water softeners regenerate:

Timed- This timer-based regeneration means that you set a particular regeneration time. Then the system will backwash, recharge and rinse at particular time intervals, using the same amount of salt and water all the time irrespective of your previous water consumption. Consequently, if you use more water than usual, you might run out of soft water prematurely. Using less water means wasting water and salt.

Metered- also known as demand-initiated regeneration is what digital systems use to activate their regen process based on prior water output. This is one of the most cost and environmental-friendly methods because no more salt and water is being used than necessary. 

Manual- This method is inconvenient and so only common with portable models. Under this method, you have to add salt directly into the media reservoir and give it time to displace the calcium and magnesium sticking to the resin beads.

7. Warranty and customer support

Purchasing online gives you a variety of products and at the best prices. 

Nevertheless, you need to pay attention to warranties, whether you bought the product online or in some stores. Some companies selling these products provide separate warranties for different system components while other after-sale services. A money-back guarantee would not hurt either; however, not every seller is going to give you one.

Lastly, think about the customer support that the company is offering. The item you are about to buy should have great and active support in case of anything. Preferably 24/7 support.


Fleck 5600SXT 48,000 Grain Water Softener is the best water descaler if you are looking to treat much water. It comes with a bypass valve; thus, you don't waste salt. Furthermore, the metered regeneration system is programmable using the LCD display, so the system only regenerates the resin on your schedule.

For small households, we recommend YARNA Capacitive Electronic Salt-Free Water Softener. This unit treats the water in your home without adding salt. It works effectively in improving the soap lather, which translates to more savings in money and time, and doesn't require any special tools or professional assistance. Moreover, it is compatible with any pipe.
