How To Choose The Best Type Of Water Softener Resin – Buying Guide

What is a water softener resin?

The softening process can’t happen without the resin beads. The minerals found in the hard water are “removed” using ion exchange. And that’s where the resin beads come to action, as the name suggests, minerals like calcium and magnesium are exchanged for sodium.

So basically you could say that the resin beads “extract” the hard minerals from water. With the time they’ll start to get full of hard minerals, then based on your water softener settings the regeneration process starts and clean them.

Water softener resin types

There are two types of water softener resin that you can buy fine mesh resin and standard ion exchange resin.

Fine mesh resin

This type of water softener resin works better at removing iron. Usually, you would need an iron filter but there are some cases in which a water softener can do the job.

It is better at removing iron because it is tighter packed and smaller than the standard resin and has a bigger surface on which iron attach. It can filter up to 10 p.p.m that is in perfect condition but in most cases, it will be 5 p.p.m.

Activated carbon can be combined with fine mesh rein in order to decrease the level of hydrogen sulfide. This will improve the feel, taste, and smell of your water.

It is recommended to add an upper flow basket to your water softener, so the resin beads won’t discharge out of the softener during regeneration.

However, there are some downsides as well, because it’s packed more tightly the flow rater is lower than on the standard ion exchange resin. That’s the reason why most water softener manufacturers prefer the standard resin.

Standard ion exchange resin

This is what most water softeners come equipped with, the standard ion exchange resin is a cation resin. The cation resin exchanges positive ions and the anion one negative ions.

Some ions with a positive charge are calcium, magnesium, iron, manganese, and sodium. Those are the minerals that you need to remove from hard water.

Those minerals can cause scale build-up in your household pipes and ultimately leads to clogs and can affect negatively your appliances.

The standard ion exchange resin removes between 4 to 5 ppm of dissolved iron. A water softener works more efficiently if the iron found in your water is ferrous in his nature.

The resin crosslink

Resin beads are spheres made out strands of polystyrene which are wrapped in a criss-cross way. The number of these intersections or the intersections of the strands are named crosslinks. And they are labeled in crosslink percentages for the resin.

Crosslinks are glued together by an agent named DVB (Divinylbenzene), the number of percent crosslinks in the resin bead will determine how strong it is thus how long it will last.

There are two types of crosslink resin:

  • 8%‌ crosslink resin
  • 10% crosslink resin

The most common resins found inside a water softener are the 8%‌ crosslink, but some may contain the 10%‌ crosslink too.

The 10%‌ crosslink resin is better when softening the water which contains chlorine, it’s gonna last longer since its stronger than the other type. Chlorine water affects negatively the resin because it damages the DVB agent or the polystyrene strands. Which may lead to the crosslink to disintegrate.

Based on your conditions and circumstances the 10%‌ crosslink may last years longer than the 8%‌. In some cases, it can double the years of high performance of your water softener.

No matter if your water contains chlorine or not, in time the resin will start to damage and you can’t control it. Its performance will decay slowly over the years. You may start to notice a drop in performance in as little as a few years.

Keeping track of your chlorine level and buying the right type of ion exchange resin can lead to:

  • higher life of the resin
  • more effective water softening
  • less water and salt usage
  • decreased cost of operations
  • way less discharge or water and sodium to the wastewater treatment plants and the environment.

The Best Water Softener Resin – Frequently asked questions

Which is the best water softener resin type for you

Pick the right type of resin depends on your condition like the iron level and what kind of water source it is. With that in mind, you need to pick a resin that fits bets your softening needs.

Private Well – Lake with a Low-Level of Ferrous Iron

For the private water sources which do not contain a high level of chlorine, a lower percent crosslink rein is recommended. Your best choice is the 8%‌ crosslink resin which does a great job for private water sources. Also, it can remove up to 3mg/l of ferrous iron.

Municipal Water

These days the municipal waters levels of chlorine and ammonia are higher, standard water softening resin will sooner or later become mush. This is due to the added chlorination and chloramines.

The bad news?‌

The damaged resin can end up clogging your pipes, appliances, toilets or end up in your drinks/foods. And eventually, it can make your water hard again. For the most municipal waters is recommended a higher percent crosslink resin. The 10%‌ crosslink water softener resin with high chemical tolerance should be your choice.

Private Well – Lake with High Iron

A good water softener resin can remove up to 3mg/l of iron without fouling prematurely. But high levels of iron are dealt better with a fine mesh resin. It can remove up to 10mg/l of iron level.

The fine mesh resin can also save you some money because you won’t need to buy extra water treatment like an iron filter.

How to do a water softener resin replacement?

Well, first you have to identify if you really need to replace the resin. A common sign is if your water softener doesn’t output any soft water. Or it starts the regeneration process and then it runs out of soft water quickly in about a day or so. If you encounter one of these problems your resin bed may be damaged.

Usually, the resin bed inside your softener can last around 10 – 15 years. But it’s life can be shortened by iron in well water and high level of iron in your water source.

How can you really be sure if your resin needs replacement?‌

Just see if your water softener uses salt and the normal rate.

If it works as intended but you don’t get soft water then the resin bed has become saturated with iron. Or has been damaged by chlorine, and it can’t be regenerated by the brine.

If the salt usage is low to none then your problem is likely to a bad valve, which means that the resin bed doesn’t get regenerated by the brine.

After doing the diagnosis and you’ve found out that your resin bed needs to be replaced here’s what you need to do:

How much water softener resin do I need?

First, you’ll have to determine how much resin you need to add, to do that you need to measure your water softener tank size. Then check out this useful table to determine the right amount.

Besides buying resin a new riser tube, rinse funnel and gravel only if your softener requires it.

After you’ve got everything needed for the replacement put the water softener into the bypass position by rotating the valve. Or you could simply turn off the main water valve.

Then on the valve head turn the dial to begin the manual regeneration, which will reduce the internal water pressure.

After doing this detach the softener from the plumbing and electrical.

You can do that by removing the fasteners which hold the valve to the bypass valve and remove the unit from the plumbing. Also, be careful to look for the o rings so you can assemble them again correctly.

After you took off the head valve start dumping the resin, you may need a friend to help you lift it depending on the tank size.

The next step is to cut off the new rinser tube the same size as the old one and insert it into the resin tank. Refill the tank with the brand new resin. Then pull the valve head back in place. Put the valve back into the “in-service” position and be careful of leaks.

If all of this seems too complicated for you then simply call a professional to do it for you. But if you’re familiar with DIYs then this can save you around $150.

How long does water softener resin last?

A resin in the best scenario lasts around 20 years, but its life can decrease drastically depening on what you throw at it.

The average user water softener resin lasts around 10 years if you have a water source with a free chlorine level up to 1.0 ppm. Chlorine levels above 1.0 ppm can decrease the life of resin in half.

The life of resin depends on the water source, and you can’t really say a fixed number of everyone.

There are various factors including chlorine, chloramines, copper, iron temperature, regeneration frequency and exposure to foulants which can decrease the life of the resin.

The fouling which directly affects the life of resin is caused by iron, it also increases the degradation reaction within the resin.

Dechlorification of the water which enters the softener can be expensive. You’ll either have to add a carbon filter or you can introduce chemicals like sodium sulfite or bisulfite. But adding chemicals is not very effective for removing chlorine.

Conclusion

Choosing the best product depends on everyone’s needs, there are products made for most people but it heavily depends on your water sources impurities. So in order to be assured that you’ve made the right decision, read the full reviews of your desired product.

If you fall in the most people category just go for the 8% crosslink resin, if your water has high levels of iron go for the fine mesh resin, and if you have high chlorine levels get the 10% crosslink.

    We rejuvenated my water softener, just plan on taking about 20 minutes to get Purolite resin in. It sticks together a bit and makes the process a little slow going. But it works great, signs of hard water around the house have almost completely disappeared since I replaced the resin.

  2. Samantha Nichols

    Purolite was used to replace the resin in my water softener. The old resin had become ineffective and I was adding resin cleaner too often to get just a few days of soft water. I found some online instructional videos that explained the process. This resin worked great as a replacement. I saved hundreds of dollars by choosing to do the work myself instead of buying a new softener. I would buy this product again and I do recommend it. On a side note, there is a funnel available to make the job of adding resin to the tank and it is well worth it.
