When assessing the Watts RV-Pro water softener, the phrase “good things come in small packages” springs to mind. This is NOT a huge, water-guzzling beast of a water softener; it’s compact, small in size and has a decent grain capacity for such a small device.

It doesn’t have a million and one smart features, nor is it blessed with anything but a standard warranty. Yet, it has made its way up to our list of best water softeners.

What Is Included with The Product?

In the box (which is quite small considering the product itself is 21×9.5×9 inches) you get 1 Watt RV-Pro water softener and the paperwork needed. Very basic instructions on setting it up and regeneration, plus your warranty booklet.

If the 1 years warranty is a concern for you, get in contact with Watts. But honestly, we felt that with regular cleaning and regeneration, this softener will last for years.

It’s a very small, simple Y valve and plug. It’s portable, of course, and ideal for camping and RVs that deal with very hard water. There aren’t many key features to talk you through, but here’s what you need to know.

It uses any kind of salt to work – table salt, pellets etc. All will work fine with this machine.

It only takes about 20 minutes to regenerate.

The flow rate is up to 4GPM, which is ideal for RVs.

The low grain capacity can comfortably keep up with a couple or family of 3 needing regular soft water for showers, drinking and cooking in an RV. It’s not big enough to deal with frequent or excessive use at home. Frankly, it just wasn’t designed for that and we don’t recommend trying it out.

What We Liked

This is a no-nonsense kind of softener. It has no smart features and as a result, it doesn’t cost you the earth to buy.

But this mini softener works. It really works with a noticeable difference, especially on very hard waters. It’s durable, strong, sturdy and, importantly, reliable. If we were stuck in the middle of nowhere with only hard water available, this is the softener we’d like to be stuck with.

Regenerating this softener is quick and simple (20 minutes of fresh water needed via the built-in flow restrictor) and as long as you regularly clean out the softener, it’s going to work for years to come. Ideally, you should regenerate once a month – if you don’t, you’ll start to notice hardness in your water again and the filter will start to deteriorate.

If you’re only using the softener once a year for your vacation, don’t forget to clean it thoroughly before storing it away.

Finally, we really were impressed with the convenience of this softener. Pretty much any salt will do, which keeps running costs down. It only takes a few minutes to connect up with your pipework too.


What Is Missing

This filter is missing many key features – there’s no denying that. The technology is simple. In fact, the devices you’re given to detect hardness in the water is just paper to dip in.

Another thing we noticed was its inability to deal with pressure, especially around the Y valve. If your water at the RV park is particularly high, you’ll want to reduce that for this softener or end up needing to replace the valve in a matter of months…

…which is particularly troublesome considering that Watts customer service and warranty is nothing special. You’ll likely need to pay for a replacement valve, which isn’t expensive but it is time-consuming to order and quite inconvenient if you’re on the road.

Then there’s the guidance on how much salt to use – it’s quite vague, which is the problem with having a softener that can use any kind of salt. It might take a little bit of experimentation to work out just the right level of salt needed for your hard water, by which time it may be the last day you’re spending at that RV park. When you move to a different park with different water or switch the salt you use, it’s going to take time to find the right ratio again.

Final Thoughts

Overall, this is a good water softener for portable use. Then when taking into consideration the cost, it becomes a GREAT water softener for portable use. It ticks all the boxes you need and leaves all the extra boxes unticked, keeping it as light and small as is possible for a water softener.

Again, we stress that if you’re going to try and use this softener for use at home, it’s really not going to live up to expectations. However, for RV lovers, campers and travelers, this is an essential companion. If you want a compact, reliable and simple softener you can set up with ease when you arrive at the next park, this is the right one for you.
