Best Water Softener Resin Buyer’s guide 2020

What is a water softener resin?

In the first place, we need to learn what actually is a water softener resin. No to mention that it is a component that plays a major role in removing the limescale from water hence removing the hardness and making the water soft.
In general, most of the water softener uses an ion-exchange method to remove the hardness from water. Although, in this process, the negatively charged ions in the resin attract the positively charged ions from water. However, these positively charged ions are calcium and magnesium commonly known as limescale, that is the major reason for hardness.
Not to mention that these resins come in different packing sizes as well as a different color. Additionally, some of these resins have the tendency to change the color as they get used. But generally, there are two types of resin.

Types of resin bead

  • Fine mesh
  • Standard Ion-exchange

Fine mesh:
First of all, this resin bead is specially used for iron removal as it helps the water softener to removes the iron up-to 10 Parts Per Million.
However, it is made up of small resin beads so it gets more effective on the iron particles in water.
In addition, this resin beads also have a specific amount of carbon in them so that the taste of water gets increased. Moreover, the regenerated water will get tastier as never before as well as you will feel it healthy and fresh.

Standard Ion-exchange:
On the other hand, there are commonly used cation and anion exchange resin beads. Although they are generally used in most of the water softeners still they are capable of removing iron from 3-5 parts per million.
In general, if you are having well water that also has a large amount of iron in it, then you clearly cannot use this resin.
On the positive side, they are quite capable of removing a large amount of hardness from water except for heavy iron. However, if we speak about heavy metal particles or heavy limescale particles then it is the best water softener resin you can have.
Not to mention that they are either made up of sodium chloride (table salt) or potassium chloride. So, these sodium and potassium ions are capable enough to replace the limescale particles hence removing hardness from water.

Working of resin bead

However, as for the working of resin beads is concerned, so its working is very simple.
First, the resin beads are filled in the brine tank of the salt-based water softener. Second, when the hard water passes through the brine tank, the resin removes the heavy metals particles from water that are dissolved in the form of limescale. Generally, these metal particles are calcium and magnesium ions.
Furthermore, the resin beads replace the heavy metal ions with light metal ions that are sodium or potassium ions. Hence the hardness from the water gets removed.
After all, the heavy metal residue went to the brine tank for getting flushed. However, some of the water softeners have the automatic flushing system but if your system does not have this feature then you need to clean the brine tank on a scheduled basis.
In the end, you need to add more resin beads either fine mesh or standard ion-exchange beads, so that the water softener can eliminate further hardness from water which is coming from the supply line.

What is Crosslink 

Crosslink is basically the percentage of divinylbenzene that is present in the resin bead you are using. Not to mention that the higher the percentage the better the resin mesh. However, this percentage also affects the price as well. So, generally, the higher percentage of resin beads have a greater price as compared to a low percentage.
In general, there are two types of crosslinks given below:

  1. 8% cross-links
  2. 10% cross-links

8% cross-links:

In the first place, it is the most commonly used cross-link. However, it is able to remove 3-5 PPM of iron present in water.
Moreover, it is famous among the well water so if you are using well water which does not have a large amount of iron in it then this is the best water softener resin bead for you. On the negative side, it will not perform that good for domestic water as it will work for the well water.
In addition, they also have a life span of 10 to 15 years. Not to mention that the life of resin beads totally depends on the quality of hard water you are receiving. So, if you are having a high level of hardness then the resin beads will las lesser than usual. Not to mention that it is price friendly.

10% cross-links:

Furthermore, when it comes to quality then you do know that it comes with a price. However, it costs a little bit when you see the outcome of this product then it will not hurt.
Not to mention that the domestic water does have some amount of chlorine present in it. So, it will help you to get rid of the chlorine particles from water. In addition, it will remove more hardness and more iron as compared to the 8% cross-link.
Moreover, for well water with a high level of chlorine and iron present in it the 10% cross-link is the best water softener resin that you can have. In addition, the 10% cross-link resin beads have a longer life span than the usual 8% cross-link resin beads. So, you do not need to worry about replacing the resin beads as compared to the 8% cross-link resin.
However, the 8% will cost you less but when it comes to the features the 10% cross-link is totally worth it.
