Buying Guide for RV Water Softeners: (Ultimate Guide)

We have different types of RV water softeners.These include salt based water softeners, salt-free water softeners and magnetic-based water softeners. Each of these type has a different way of working as discussed below in details.

Types of Water Softeners

Magnetic-Based Water Softeners

In this type of softener hard water that contains minerals ions is passed through a magnetic field which diminish the effects hard water will have on your plumping pipes in your RV. Although mineral ions such as calcium, magnesium and ions will not be removed completely.

This type of water softener is actually considered as more of an effective unit rather than an elimination unit. Despite of these they still have their own set of advantages that makes them solid options for RV owners. For example, they make sure all the minerals ions in hard water such as calcium and magnesium are completely eliminated from hard water.

Another benefit is that they are less expensive as your compared to other softeners. So if you’re a bargain buyer you should most definitely consider this type. There small design makes them portable and makes storage easier.

Salt-Free Water Softeners

You can also go for salt free water softeners. These type of water softeners utilizes nanotechnology with an aim of changing the structures of molecules in water from being scale building into non-scale building.

They have a filtering media where water passes through. As the molecules flow through the tank they get restructured where the mineral ions present in the fixtures and pipes get positively affected while water flows through them. This means the plumbing system is descaled.

Another remarkable benefit of salt-free water softeners worth emphasizing on is that they don’t require much maintenance. This is due to the fact that there is no need to buy or add salt. Another major plus of this type of water softener is that it prevents wastage of water as it does not need to undergo regeneration cycles. Also these models don’t require electricity to work.

Salt-Based Water Softeners

The most commonly used types of water softeners are the salt-based ones.As seen above these models work by replacing the calcium and magnesium ions with sodium ones preventing hard water from the descaling your RVs plumbing system.

Most RV owners prefer salt-based water softeners as most of these models come with two tanks;one tank makes use of resin and other one makes use of brine.

These type of water softeners however, pose one drawback, that’s they pose a challenge to move around and store because of their huge size. Unless you have limited storage or don’t want take into much salt, then these models are the best options available.

Here are a few things to consider before making a responsible decision about buying and installing a water softener in your home. 

Benefits of Water Softeners


The first decision you’ll make regarding buying a water softener is the type of water softener. With this in mind, I will make this easy. If you want the most effective model, then you should go for a salt-based water softener. These are the most effective.

Salt-based water softeners have a few drawbacks though, first, they’re a bit expensive as compared to other types, second, their huge size means they will pose a challenge to move around and store, and lastly, they require a lot salt which is expensive also.

If you feel like these pros will cause concern, then these two other types of water softeners might fit your needs more; salt-free water softeners and the magnetic-based water softeners. Either one has a solid compact design meaning they won’t take up too much space. They also don’t use a pinch of salt.

The fact that they don’t use salt makes them less effective. It’s also important to note that the salt-free models don’t eliminate the calcium and magnesium ions but instead they make them change form by crystallizing them. This simply means you’re still exposed to these hardness-causing ions.

So considering all these, I believe you’ll be able to make a decision and purchase one that best suits your preferences.


Another thing to consider before buying a water softener is the manufacturer. Several manufacturers continue coming up with high-quality products. Picking a top-notch manufacturer increases your chances of the satisfaction with the model you buy.

With this mind, it’s important to make sure the softener you buy comes from one of these brands, On the GO, ABC waters, mobile soft water. All of these manufacturers will provide you with excellent products that’ll perfectly fit your preferences.

In case you’re looking for a product from a manufacturer not mentioned above, then ill recommend that you’d go through the customer reviews before deciding.


You should always pick a water softener with a size that best fits your preferences. If don’t have much space, then I’d advise you to go for a softener that doesn’t take much space. In all essentials, size is a crucial factor to put into consideration before buying a water softener.

Ease of installation

Maybe the most important thing to consider before buying a water softener is the ease of installation. Quite frankly, purchasing a water softener that will give you a hard time during installation will not be a pleasant experience. Thus, it’s essential that you check the installation process and steps and make sure you can handle them before settling for a product.

These steps are available online, and if you can’t find them online check the customer reviews section. Many will prefer a unit with a simple installation process, one that will take at most 2 hours to complete.

A complicated process will require an expert, and this means extra charges. No one wants this. Therefore, if you don’t want to spend much I’d advise you to go for a product with a simple installation process.


Controls usually differ among different units. Some units come with automatic controls while others require you to set a predetermined time for the regeneration process for an automatic period, say once after every two days, once a week, etc. through a controller system.

The automatic units allow you to choose a specific time for regeneration. They also keep track of the number of water gallons that pass through allowing you to regenerate only when necessary. These are some of the things that make you happy with your product.


The capacity of a water softener is measured based on the number of grains of hardness in water it can get rid of. The capacity of a water softener is measured by multiplying the GPG (grain per gallon) with your family’s water consumption in gallons. 

With this information, you should know what grain-capacity model will suit your family needs. If an 8,000-grain capacity can handle your soft water needs, then you’d go for a higher capacity model. Maybe one that’s rated 10,000-grain capacity or 16,000-grain capacity.
