The water softener requires resin to suck hard minerals present in your hard water.

Most of these resins last for about 10-20 years when feed with tap water and when it reaches its life expectancy it no longer provides, soft water.
Most resin manufacturers recommend a lifetime to be 10 years, but this can be lower depending on the condition of your water.
Therefore resin beads do not last forever they need to be replaced when it reaches its life expectancy or no longer hold hardness ion in your water.

What is a water softener resin?
It is a media inside the ion exchange water softener minerals tank that used to remove hardness in your water.
The resin has a negative charge that attracts a positive charge in your hard water making your water soft.
So if you are using a salt-based system, the resin is one of the critical products you need for your system to work effectively or produce soft water.
The size of these resins ranges from 0.3-1.2mm.

Softener resin types
Which water softener resin is best for you?
Most people become confused when it comes to choosing the right resin for your unit.
There are two different types of water softener resin available in the market.
- Fine mesh resin
This type has small sized beads which are used to soften water and remove iron up to 10P.P.M.
Since the fine mesh resins are small-sized, you need an upper flow basket so that the beads will not come out during regeneration.
- The standard ion exchange resin
Most water softeners use Standard ion exchange resin which is excellent to soften water and remove iron between 3-5P.P.M.
It regenerates using either Sodium Chloride/salt or Potassium Chloride.
Standard resin comes into two sizes: 8% Crosslink and 10% Crosslink.
The cross-link is a connection between the inside resin bond.
For easier understanding cross-link is like twisting a string.
Water softener resin 8 vs 10
10% has more connection that holds resin together making it last longer than 8%.
10% Crosslink is suitable for chlorinated water without iron so best for municipal water. We recommend that households choose the 10% cross-linked resin if they get it from the city or municipalities which contain chlorine.
The 10% Crosslink is more costly compared to 8% crosslink resin.
8% Crosslink is commonly used in most places. It is best for non-chlorinated and without iron so best for well water

How long does the water softener resin last
Most manufacturer recommends resin to last 10 years, but the condition of your water determines this.
Water supplied by municipal has high content of chlorine that can reduce lifespan of the resin
Well water has high content of iron and that can affect the resin life span
When do you know it is time to change the water softer resin?
- Once the resin has reached its life expectancy. Most manufacturers indicate the life expectancy on the product label. Check product label before buying to be sure how long will your resin lasts
- When the resin reaches its life expectancy, the fines will start coming out and come into the house clogging faucet.
- When you notice a resin tank has some sediment particles. You need to replace the resin and install a sediment filter before the water softener. There are salt-based water softener that comes with sediment filter like (sample and link)
- When the resin tank has sat for time unused, and you sense a strong odor. You can clean resin using cleaner but if it does not solve the problem dump resin and replace it with new ones.
- If your resin is coated with iron, you can remove it by cleaning with a strong resin cleaner but if the problem persists replace it with a new one.
- If the water pressure starts to be lower than it is used to be.
- When your water softener starts producing hard water. It does not give soft water like before.
- In case you clean your brine and resin tank, change the salt, and regenerate the system, the water coming through remains hard. This means its time to change resin
How much resin do you need for replacement?
If you want to know how much resin you need for your water softener make sure you are sure the size of your resin tank.
Your tank diameter matters. Some tank has a sticker somewhere that tells you the size while other you have to take the measurement yourself.
The sticker measurement is written as 1035. Meaning the first two digits (10) is tank circumference/width, and the last two is tank height (35).
If your tank doesn’t have a sticker, you can measure the tank.
How do you take the size of your tank?
Measure the height of the fiberglass tank that contains resin.
Sometimes the tank has a decorative plastic jacket placed over the fiberglass/polyglass tank.
Make sure don’t measure that plastic jacket it is meant for protecting your tank, so it is not the real resin tank

Then measure the diameter/width of the tank.
Measure the width or use the string to measure around the tank divide by pi 3.14.
For instance, if your width or circumference is 30 divide by 3.14 so the width inch is 9.5.
Then round down to the whole number, so that is 9 inches.
Typical tank sizes and resin used
9″ x 48″ – 1.0 cu ft.
10″ x 54″ – 1.5 cu ft.
12″ x 48″ – 2.0 cu ft.
13″ x 54″ – 2.5 cu ft.
14″ x 65″ – 3.0 cu ft.
You can use APS water calculator to give you the exact amount of resin you need for your softener.
Never fill the media to the top because different media behaves differently some require space for expansion when backwashing
How to replace Water softener resin
- Turn off the system and disconnect from the power source
- Disconnect valve head to the bypass valve
- Disconnect valve head from the tank
- Find someone to help hold the tank
- Pout out resin beads and gravel

Bonus video about water softener resin
How can I tell if I have Standard ion exchange resin or fine mesh resin?
It is hard to tell which resin type you have by looking using naked eyes.
So how do you the difference?
Take a pinch of resin and place on the palm of your hand.
Squeeze using your index figure so if it clumps that is fine mesh resin and if it forms like a ball that is the Standard ion exchange resin.
The resin beads is an important media in every water softener.
Without resin, you cannot get your hard water treated unless you use a conditioner that only descales but does not remove hardness in water.
Water softener resin how it works?
Resin is a media found in the water softener tank to remove hard minerals in the water. They are negatively charged and hard water is positively charged. So when hard water comes to contact with resin, the resin attracts minerals in hard water leaving you with softened water
