Buying Guide for an RV Water Softener

In this section, we’re going to consider a few factors and things that you’d always take into consideration when purchasing a water softener. Buying the right water softener for your RV is important because it’s a longtime investment. 

best RV water Softeners

The first thing to consider is the type of water softener. On this, we will start with the salt-based RV water softener, which is the most effective if you’re dealing with a salt solution.

However, take note that these types of water softeners come with some pros as well. First, they’re a lot more expensive, second, they occupy a lot of space and lastly they require salt to work.

Apart from the salt-based RV water softeners we also have the electronic system ones. These make use of electronic wires to recharge or regenerate.

The first benefit of these is that they take less space as compared to salt-based water softeners. But they come up with drawbacks as well, the lack of salt means they’re less effective than the standard salt-based ones.

Another type is the salt-free models which as we have reviewed above are incredibly effective, they do, however, have drawbacks as well.

For instance, they don’t eliminate the issues causing mineral ions but instead, they only make them change the form, they just crystallize them making them not to scale your surfaces, but in a real sense, you’re still exposed to these ions they are not eliminated.

Another option is the magnetic water system, which makes use of magnets that are attached to the device’s pipe. These magnets mean that the way mineral ions are charged will be disrupted, which further prevents clogs in pipes.

Therefore, considering all these benefits and drawbacks that come with each type, we can all agree that you have to consider a lot before deciding which type of RV water softener to settle for.

Size is another crucial factor you have to consider. And since you are looking for a water softener designed for your RV, you have to pick a size, which is indeed suitable for it.

That’s why it’s always advisable to go for a portable water softener- one that means that you can take it anywhere. A portable water softener appears in a portable tank style. You can also utilize standard table salt.

The size of the portable water softener is just enough to ensure all your soft water needs are met. It’s big enough to the extent that it can accommodate up to 4-5 users.

Another essential factor you must consider when choosing an RV water softener is the capacity of the water softener. The capacity of a water softener is measured based on the number of grains of hardness in water it can get rid of.

We’d recommend finding a water softener that’s rated 8000-grain capacity and above. Such capacity means the water softener can handle at least days before the need to regenerate. To determine the capacity of water softener that you need, multiply the GPG (grains per gallon) value with your entire family’s water consumption in gallons.

For commercial water consumption, we’d recommend water softeners rated 16,000 grains capacity and above

If an 8,000-grain capacity model may be unable to meet your soft water needs, then avoid buying it and instead go for one rated 10,000 and 16000-grain capacity, which will both meet your needs. Also make sure that it is not too big, though, so you can avoid wasting money.

Find out if the water softener you are planning to buy holds all the features that you need. Note that some of these softeners can be operated manually, causing the need to regenerate it every time you require softened water. Some softeners, on the other hand, are equipped with high-tech features and modern qualities.

Some tend to restart automatically, which is more convenient since you will no longer have to be burdened by constant renewal and regeneration. If possible, choose this type. The favorite one among consumers is also usually the meter-based one as it facilitates the automatic regeneration of water, saving you time and effort.

This refers to the speed through which a water softener can produce soft water which is usually measured in grains per gallon (GPM). The flow rate varies from one model to another.

It’d be very important to determine the specific models’ flow rate before you decide to buy. This will mean that you can easily compare it with the maximum usage in your RV, helping you determine which one is best suited for your RV.

 Therefore, you must check the actual installation process and steps and make sure you can handle them, before settling for the prod
