Types of RV Water Softener:

Salt-Free Portable Water Softener:

As the name indicates, salt-free water softener does not use salt to soften the water. Rather they use some other chemicals to soften the water.  Let me tell you one thing, actually, they do not soften the water, instead of this, these units descale conditions the water.  This means you won’t get rid of hardness causing elements. They are still there in your water but in other forms that is crystal. This way these elements won’t cause limescale build-up. Therefore, your plumbing and appliances will remain safe and sound.

Salt-Based Portable Water Softener:

Salt-based water softener works by using salt. These water softening units remove calcium and magnesium ions from the water in exchange for sodium ions. Most RV owners prefer a Salt-based water softener, as it will completely protect your RV’s plumbing system from hard water damages.

Magnetic Portable RV Water Softener:

This type of water softener creates a magnetic field around the pipe in order to soften water. The magnetic field will change the properties of hard minerals which in turn converts hard water into soft water. Magnetic water softeners are really very simple to install. But there is a downside to it. They do not remove calcium and magnesium from water rather they change their properties. This way calcium and magnesium will still there in the water.

If you are on a budget and can’t afford salt-based and salt-free water softener, then a magnetic water softener could be a perfect option for your RV, since they are smaller in size.

Factors Consider While Buying a Best Portable Water Softener:

Choosing the best portable water softener can be a difficult task especially when you are buying it for the very first time. But let me tell you, if you are buying a portable water softener for your RV’s then it would be a lifetime investment. Every time you or your friend uses your RV, he will get complete benefit from it.

Let’s come to the point!

Portable water softeners are more or less similar to the whole house water softener, but you need to keep few things in mind as you are purchasing it for your recreational purpose.

Type of Portable Water Softener:

First, decide which type you are going to buy. Generally speaking, most RV owners prefer buying salt-based portable water softener as it efficiently removes hard minerals from the water. Though they are a little bit expensive but trust me, it’s a one-time investment. In addition to this, it utilizes salt which may be harmful to people who are on a sodium-restricted diet.

But don’t worry, we have other two options as well, that are: salt-free water softener and magnetic water softener, which are quite affordable. How do they work? Check out types of RV water softener.

Size of a Portable Water Softener:

Make sure that the portable water softener that you are going to buy must have an appropriate size. By appropriate I mean, a size that suits well to your recreational vehicle. A water softening unit should be compatible with the space that your vehicle has. The size should be such that that can be carry and placed anywhere.

Believe me; a portable water softener for you RV will add more value to your vacation trip.

 The capacity of RV Water Softener:

The capacity of a water softening system is defined as, how much hardness it can remove before it needs to regenerate. If you need to get rid of many grains of hard water every week, then you should buy a water softener that has a large capacity. Most of the RV water softener has a grain capacity of more than 15,000 grains.

Remember choosing a water softener of lower capacity than your need is simply a waste of money. So it is advisable to calculate how much grain capacity will be needed. For this, just multiply the GPG value by the number of gallons of water that your family consumed.

Flow Rate of Portable Water Softener:

Flow rate is defined as the speed of filtered and soft water that a water softening system provides in form of a gallon per minute.

You know Different models of water softener supplies water with different flow rates.

But you have to keep in mind that the larger the grain capacity of the water softener, the higher will be the flow rate and vice versa. So before buying a portable water softener, calculate the amount of water you would use and accordingly its peak flow rate that you would require.

Maintenance:

There are some units that require more maintenance than the other. Of course, you don’t have enough time in your busy schedule to maintain the water softener frequently. So it is preferable to look for a water softener that requires less maintenance

Yes, there are certain water softeners that require no maintenance at all but of course, they are a bit costly.

So before purchasing a water softener keep in mind your budget, your schedule, and the maintenance process.

Ease of Installation:

Make sure that the water softener you are planning to buy must be easy to install. The installation process should not be much complicated. Otherwise, you will have to pay hundreds of bucks to the plumber for installing the unit in your RV. The installation process should be so easy that even a layman can install it.

Our Verdict:

Portable RV water softeners will keep you and your RV safe from hard water damages. It will not only beneficial for your appliances but your skin and hairs as well. And of course, you can’t ignore your skin and hairs even on a road trip. So it’s the best way to care for them.
