Major Reasons for Getting a Softener for Your RV
Water may contain minerals like calcium potassium and iron that increase the water hardness levels. A water softener helps filter out these heavy elements with the help of a specialized filter.
These water softeners are designed for homes or commercial buildings but you can install them in an RV to take full advantage of its cleaning features. Here are some major reasons for using a softener in your RV:

- Filter Out Harmful Minerals: Installing a water softener helps to filter out the harmful minerals from the water preventing build-up in RV appliances.
- Increased Efficiency of Water Heaters: The heavy quality of minerals increases the boiling point. Equipping the RV with a softener boosts the efficiency of the water heaters.
- Effective Against Corrosion: Different minerals can react with piping materials and cause corrosion. Getting rid of the mineral ions reduces this chance.
- Better Taste: Water filtered through a softener will taste better.
- No Limescale on Taps: With a unit installed in your RV, you will avoid that limescale on your taps and showerheads.

6 Important Considerations Before Investing in an RV Water Softener
There are numerous factors that you need to look out for when purchasing a softener. I have compiled below a quick guide to highlight the important considerations so your investment won’t go to waste. Let’s check it out!

1. Choosing the Right Type of RV Water Softeners
With the use of a water softener, you ensure water quality and the lifespan of your appliances/plumbing system. There are three types of water softeners for a recreational vehicle and they are as follows.

Magnetic Water Softeners – Attracting the Ions
As the name suggests, the magnetic water softener uses the concept of magnetism to get rid of minerals that cause the most water hardness. These water softeners have the following qualities:
- A very economical investment;
- These water softeners are small in size;
- These are also lightweight;
- You can install them in any type of RV.
Salt-based Water Softeners – Replacing Minerals with Salt
Salt-based softeners are considered the most efficient for removing hard minerals from the water. Here are some of the qualities to learn:
- These water softeners are larger compared to other types;
- An ion exchange water softening process exchanges sodium ions with the minerals;
- A bed (filled with resin beads) traps the hard minerals and swaps them with sodium ions;
- To remove the calcium and magnesium captured in these softeners need regeneration multiple times.
Salt-free Water Softeners – Turning Minerals into Crystals
The third type on my list also works like salt-based water softeners but potassium chloride salt is used instead of common salt. Here are some of its features:
- Salt-free water softeners trap magnesium and calcium ions while replacing them with elements from the salt;
- If you are following a salt-free diet then this is the best softener type for you;
- Minerals turned into crystals saving the plumbing system of your RV.
2. Higher Grain Capacity Offers More Filtration Capacity
The threshold of a water softener to remove heavy minerals such as magnesium and calcium before needing regeneration is called its grain capacity. The grain capacity should be greater than at least 3,333 GPS.

However, remember that the higher the grain capacity the higher the price would be.
3. Water Softeners Offering Portability
When choosing an RV water softener you need to keep in mind the ease of transportability. This is to ensure that it fits well in your vehicle and fulfills your water needs. Here are some important things you need to consider:
- Calculate your water usage requirements and select a unit that balances size and performance;
- Find a portable water softener that’s compact yet capable of providing sufficient clean water.

4. Ease of Use and Ready to Install
You should invest in a user-friendly water softener for your RV. This is necessary while considering the convenience of having clean water without a complex process of use.
Here are some key factors that can help:
- Choose water softeners that are ready to use and don’t require tools or electricity for installation.
- Look for a unit that can be set up right out of the box.
- Give importance to hassle-free operations like easy regeneration process, availability of parts, and good customer support in case you need any help.
This way you can focus on enjoying your RV lifestyle while the water softener works perfectly.
5. Maintenance of the RV Water Softener System
Here is a breakdown of the maintenance cost:
However, keep in mind that the maintenance of your RV water softener from professional servicing companies is not available everywhere. So, you have to consider an option that offers prolonged use. Here are some tips to ensure that the filter works efficiently.
- Regularly refill the salt in the brine tank to keep the water softener functioning effectively.
- Invest in high-quality connectors and pipes.
- Clean the pipes and connectors after routine checks to ensure a better lifespan.
- Make regular inspections to ensure that the unit is clean and functioning properly.
6. Materials Used for Manufacturing
Always prefer high-grade materials used in your RV water softener. Here are some smart tips to follow:
- Water softeners manufactured using NSF-certified materials offer the best safety standards.
- Water softener tanks made via HDPE (High-density polyethylene) should be preferred due to their chemical resistance and durability.

FAQs
How long do RV water softeners last?
RV water softeners last up to anywhere from 5 to 15 years.
Do water softeners cause kidney stones?
No, softened water has low levels of minerals while hard water has increased calcium, potassium, and iron levels. A high amount of Potassium mineral buildup is one of the major causes of kidney stones.
How do I store my RV water softener when it’s not in use?
The best way to store portable RV water softeners is to drain the water out and let it rest on its side on a plain surface.
Conclusion
The final say is that when buying a portable RV water softener, carry out thorough research as it is the most critical part of product selection. Keep an eye on models that have high grain capacity, NSF certification, offer excellent water flow rate (GPM) and have a reasonable price tag. While all these factors are essential you also need to check out its performance and maintenance cost.
