Importance of Water Softeners in RVs

There are a lot of reasons why you may want to use a water softener in your rig. Here are a few:

Inconsistent Water Sources – As an RV traveler, you’re constantly exposed to new water sources. If you take a look at the USGS water quality map, you’ll find that many areas have extremely hard water, while most areas in the US have at least moderately hard water. By getting a good RV water filter and a water softener, you can ensure you always have access to high quality water, wherever you go!

Appliance Damage – Hard water can wreak havoc on your RV’s plumbing system and appliances. Since RV repairs can be expensive and cumbersome, it’s often a great investment to reduce the risk of damage in the first place by getting a water softener.

Skin & Hair Health – Hard water can negatively affect the health of your skin and hair, causing dryness and brittleness. A water softener can help significantly, and also reduces the amount of soaps and shampoos you need to use.

Filter Lifespan – If you also use a water filter in your RV, you’ll likely find that using a water softener as well can help to extend the lifespan of your filter. In fact, water softeners can help extend the lifespan of many RV components and accessories!

Mineral Stains – Have you ever noticed mineral buildup or stains on your shower, faucet or toilet? If so, chances are hard water is to blame. Using a water softener can help prevent this unsightly buildup in the first place!


How We Chose 

There are a lot of good water softeners on the market, but they’re not all made for RV use. To make our selections, here are the factors we focused on:

Size – Anyone who has traveled in an RV could tell you that space is almost always at a premium. You simply don’t have the amount of free space that you’d have in a traditional home, so you need to carefully consider your purchases. We focused on compact, RV-friendly models for our recommendations.

Capacity – Since you’ll likely be using the water softener for the entire RV (sinks, showers, etc) you’ll still need a decent capacity on your softener. We focused on models with at least 16,000 grains, which is a good capacity yet still able to fit in a relatively small space.

Quality – Of course, the quality of the product was an important consideration! We looked at manufacturer specs, third-party reviews and our own data to determine the quality, effectiveness and durability of each product we considered.

Warranty & Support – Even with good quality products, issues can crop up. We focused on models with good warranty coverage, and a well-rated customer support team to clear up any potential issues.
