Noticed a change in your water softness recently? It’s not because of your water softener, but because of the water softener resin, which probably should be changed as soon as possible.

Resins are crucial when it comes to softening water, and unfortunately, they don’t last long.

This happens partly because our water has become so hard and full of minerals that it is almost impossible for resins to last longer than we expect them to.

No worries, because we’ve done research on the topic and found out which water softener resins are worth the money, patience, and hassle. Check out our guide below.

How Long Can I Use The Water Softener Resin?

The resin can last around twenty years according to some optimist sources. 

The water that comes to your household is another influential factor. Yet, you might expect half of this period to be your optimal time.

When Should I Put a New Water Softener Resin?

To have a resin that doesn’t need frequent replacement may be an important characteristic of a good water softening system. 

Yet, you should know that the regenerating cycle of your unit will affect its durability.

The replacement comes after many years of constant use. 

If your water supply comes from well water it is normal for it to contain all kinds of minerals, both toxic or useful.

Can You Clean a Water Softener Resin?

The only obligation you have with the softener resin is to clear it on a regular basis. 

The amount of resin to use stands on the packaging instructions. When you aim to do some more specific things, refer to the water softener manual.

How Does A Water Softener Work?

Trading them for sodium, which is a softening mineral, water softeners try to remove hard ones such as calcium and magnesium. 

This is one of the most common methods of softening known as ionization. The resin beads are the hard water ions to which hard water adheres. 

To maintain balance in the water, sodium ions release in it. 

What allows this ion exchange to happen is the resin media. 

It attracts opposite-charged negative ions by acting like a cation (positive-charged).

As time goes by, hard water minerals saturate the beads. 

A regeneration (cleansing) of the system follows when this happens. Through the softener tank, passes water coming from the brine tank and is rich in sodium. 

While the resin recharges with sodium ions, calcium and magnesium ions get back into the water and go away. 

Your mechanism is now ready to work in the same manner as before.

When Does My Water Softener Resin Need Replacing?

Ten years is the lasting time of the water softener resin. 

Depending on the quality of your municipal water supply or if your water comes from a well, this can vary.

What can reduce the lifespan of the resin is the high chlorine content in some municipal water supplies. 

What can further degenerate resin is the high iron content and sand particles in your well water.

When your water is not soft anymore may be the first sign that your resin might need replacing. 

What may happen is that your soap won’t perform as well as you’re used to or you might notice hard water stains on your glassware.

The water coming through will remain hard despite cleaning your brine tank, changing the salt, and regenerating the system. 

The reason for this happening may be the end of the effectiveness of your resin.

A sudden interruption in the high pressure of your water flow can be some of the causes of ineffective resin. 

It can be the reason for resin beads to smash against the sides of softener tanks. Beads can crack or break because of this.

What can cause swelling of the beads to a larger size is the loss of strength of the resin due to chlorine sedimentation. 

Beads can crack or break as there’s limited room in the tank for them.

As they draw in minerals and then release them again, the beads are getting larger and smaller. 

This process leads to rupture over the course of time.

The volume in the tank will drop as a result of the beads getting damaged or cracked. 

When the tank gets regenerated, the bits can fall off and get washed away. 

Your water won’t be soft as it used to due to the lasting effect of this area for ion exchange that takes place.

Your tank undergoes regeneration by leaving behind iron oxide with the reaction of iron and oxygen. The cleaning salt builds up on the resin beads instead of cleaning up the resin. 

The performance of our system won’t get better, and the availability of the area for ion exchange will drop.

When Should You Replace Your Resin? 

You are cleaning out your brine tank after checking the salt in it. 

Your water softener is churning out hard water although you’ve regenerated your system as well. You may use some better water softener resin to replace the old one in your brine tank.

It is a task you can complete on your own by following the directions of your manufacturer. 

You won’t have to call a professional and you’ll save some money.

We are bringing you details about domestic water softener systems some of which may also be good for commercial use. 

Once in ten years is the advice for change that many manufacturers recommend. 

Yet, be ready to make changes to your resin whenever it is necessary by keeping a close eye on it.

Final Verdict

As it is quite obvious, the features of the softener resins are pretty straightforward. 

They will depend on your willingness to spend on more dependent products or your dedication to contribute to your budget. 

Our advice is to try the dependent ones for frequent, and more budget-oriented offers if you use the water less often.
