How Long Do Water Softeners Last?

Water softeners are a great thing to have, especially if you live in an area with particularly hard water. Whether you’ve just bought a new water softener system, or you’ve had it for years, you may be wondering how long your water softener will last for.

How Long Do Water Softeners Last

There are ways to help prolong the life of your system due to regular maintenance checks. In this article, we will be discussing how long your water softener system will last and how you can help prolong its life.

What Does A Water Softener Do?

Water softener systems are a very popular appliance, as the majority of homes in America have this system installed. In hard water, there are magnesium and calcium particles, which aren’t dangerous to consume.

However, they can cause your hair or skin to dry out and a buildup of sediment or lime scale will occur on your plumbing fixtures.

Therefore, by installing a water softening system, you are reducing and eliminating these issues from occurring.

The hard water passes through the resin beads, and this eliminates the impurities found in your hard water. Thus, an ion exchange causes hard water to become soft.

How Long On Average Will A Water Softener Last For?

The lifespan of a water softener can differ due to the model and type of unit that you have brought. On average, a water softener could live between 10 and 20 years, but this varies for various reasons.

Although, it should be noted that no appliance will last forever, and the older your system gets, the more likely it is that it will begin to break.

If you notice issues with your water softener unit after 5 years, then we would suggest repairing the unit. Although, if the unit is over 10 years old, then it is better to replace the unit altogether.

The first sign that you notice that there is something wrong with your water softener system, you shouldn’t ignore it. Call a professional so that they can come over and insect your unit.

The sooner someone looks it over, the quicker the repairs can happen, which means you reduce the chances of a serious failure which could be quite expensive.

A lot of people install their water softener and then forget about it. Yet, really you should be keeping a regular eye on the system to make sure that everything is still working correctly.

Otherwise, you will only know something is wrong at the last moment, and they could cost you a lot of money in the long run due to repairs or replacements.

How To Prolong The Life Of Your Water Softener?

How To Prolong The Life Of Your Water Softener

It is important to keep your water softener maintained, this is to help prolong its life so that it keeps working efficiently for a longer period of time.

There are a couple of other things that you can do, to keep on top of your water softener, which will then allow your system to last much longer than if you didn’t do any of these things.

Change Filters

Over time, filters can become ineffective, which means your appliance needs to work harder to filter the water. Therefore, it is advised that you change the filters once they become ineffective.

In the manual that is provided to you with your water softener system, it will walk you through how to change the filters easily.

For a Kinetico system, you can use in-line filters, and these do need to be changed every few months.

Make Sure The Brine Tank Is Topped Up

The regeneration process is a really important part of your water softener system. The process typically happens at night.

It allows a brine solution to enter the media tank to replenish and recharge the resin beads so that they will continue to work the daytime you need water.

As a result, it is important to make sure that the brine tank is always filled up with water and salt. You should refill the tank before the water is visible in the softener cabinet or brine drum.

In addition, you should be aware of the salt you are using. A salt pellet or cube is a much higher quality solar or rock salt. Not only will it save you money in the long run, as they last longer, but they also prevent the chance of bridging occurring.

Watch Out For Salt Bridges

You should only add more salt when the tank is only ⅓ full. Then, when you can salt the tank, try to leave around 6 inches of the tank empty at the top.

Sometimes the salt can form bridges and will prevent the brine solution being as effective as it needs to be.

If you see a salt bridge, remove it as soon as possible. This is only an issue with salt crystals, but it’s something to keep an eye out for.


You don’t want your water softeners working harder than it needs to. Therefore, check the settings you have set. You want them high enough to soften your water, but not too high.

However, you also don’t want them too low either, otherwise the tank won’t work properly. In this case, seek the advice of a professional to make sure what settings are necessary for your water type.


On average, as long as you look after your water softener system, it should last between 10 and 20 years at most. It is important to maintain it, as this will prolong its life, so you don’t have to spend more money on repairs or replacing the system.

We hope this article has been insightful. Now you will know how long your water softener should last for and what you can do to help it last longer.
