, the SofterWater™ Inline Caravan Hard Water Softener will reduce scale formation on hard surfaces and within appliances.

It will also make your water act like it is softer. This means your detergents and soaps will be more effective, clothes come out of the laundry cleaner, and your water will be gentler on your hair and skin. 

What Does It Do?

As any experienced traveller knows, many parts of Australia have ‘hard’ water, which contains a high level of dissolved minerals and salts.

Hard water can cause a variety of issues for travellers, including the development of limescale — a hard crusty build-up of minerals which have precipitated from the water.

Limescale isn’t just unsightly. It can cause significant damage to your caravan, RV, or motor home’s plumbing and appliances. It can work it’s way into solenoids, coat boilers, and cause taps to malfunction. If your plumbing or appliances malfunction during a trip, it can lead to very costly repairs and possibly ruin your trip.

Hard water also leads to other problems, like dry hair and skin, spots on glasses, scratchy clothes, and fabric stains.

The SofterWater™ Caravan Hard Water Conditioner is an inline water softener designed to deal with these issues.

It changes the electrical charge of dissolved minerals in the water, forcing them to bond together in colloids which remain suspended in the water. These suspended colloids don’t form scale as easily, which helps to protect your RV, motorhome, or caravan’s water consuming appliances and internal plumbing.

After installing the SofterWater™ Caravan Hard Water Conditioner, it will be much easier to form a lather, so showering is a more enjoyable experience and your skin/hair will be softer. Clothes will also come out cleaner from the washing machine, as your laundry detergents will operate more effectively.

The best part of SofterWater™ products — this process does not involve any chemicals and does not require electricity. Once installed, your SofterWater™ inline Caravanb Water Conditioner will last for many years to come.

Comes with a Lifetime Manufacturer Warranty (See manufacturer website for details).

SofterWater™ Inline Caravan Hard Water Softener – Key Benefits

  • Protects Your Caravan, RV, or Motor Home’s Appliances and Pipework From Damage
    Scale build-up from exposure to hard water can cause serious issues with appliances and pipework. It can cause blockages, leakjs, blocked solenoids, coated heating elements, malfunctioning switches, damaged taps and much more. By reducing scale build-up, you can prevent these issues and ensure your caravan’s plumbing remains reliable and watertight.
  • Improved Energy Efficiency 
    When scale coats a heating element, it can make it more difficult for an appliance to reach correct operating temperature. It may have to stay on for longer, which leads to decreased energy efficiency. Reducing the scale build-up in your van, motor home, or RV will help you avoid this issue.
  • It’s Easier To Keep Your Caravan, RV, or Motor Home’s bathroom Clean
    In addition to being unsightly, limescale is really really difficult to move. In most cases, either a lot of elbow grease or toxic cleaning products will be required to remove it. After installing the SofterWater™ Inline Caravan Hard Water Softener, any mineral build-up that does occur will be quite soft and easy to remove with a domestic cleaning product.
  • Your Water Won’t Be As Harsh 
    Have you noticed that your hair and skin feel dryer when you travel through areas with hard water? That’s because water with high mineral levels can leave a film on the skin which reduces moisture. This is the reason why hard water will also worsen conditions like psoriasis and eczema. By changing the form of the minerals present in the water, the SofterWater™ Inline Caravan Hard Water Softener reduces this drying effect.
  • Easy installation
    The SofterWater™ Inline Hard Water Softener (no fittings) has a standard 1/2″ Female BSPP connection on the inlet side and a 1/2″ Male BSPP connection on the outlet. It is designed this way so you can connect to a standard 1/2″ male water outlet under the sink. You can also use a wide variety of fittings with it, including brass push on hose fittings and 12mm John Guest-style tube fittings. This means you can install it in one of several locations inside or outside your caravan. There is also a version with 3/4″ Female/Male BSPP fittings available (talk to us for more detail).
  • Less Soap and Shampoo Required
    SofterWater™ conditioners make it easier to form a lather with detergents and soap. You’ll find your showers much more enjoyable and won’t waste as much shampoo or body wash, which can leads to big savings during long trips away.

SofterWater™ Hard Water Softener For Caravans – How It Works

  1. SofterWater™ units are made using a special foundry process, combining a group of metals on the anode and cathode galvanic scale. This alloy has a non-sacrificial anode, which means it will never need replacement.
  2. As water flows into the unit, it moves through a series of baffles causing intense galvanic reactions.
  3. Most of the minerals in the water are attracted to the sites of these reactions, forming clumps which remain suspended in the water instead of forming scale.
  4. Any scale that builds-up is much easier to remove as it does not form as a hard crust.

It’s important to note that each SofterWater™ unit is designed for a specific flow rate range. The SofterWater™ Inline Water Softer for Caravans is designed for mobile vehicles like caravans, motor homes, and RVs, which typically have a flow rate between 6 and 18 litres per minute. It can also be used on any type of appliance with a similar flow rate.

If you need a larger unit for a faster flow rate, let us know. There are several versions of the SofterWater™ device, designed to suit specific flow rates.

Do I Still Need A Water Filter?

Yes, installing a caravan water filter system is usually a good idea.

Does The SofterWater™ Caravan Hard Water Softener Require Maintenance?

No it doesn’t.

Once installed, the unit will last for many years to come. There are no replenishable internal components to change or parts that wear out. The internal alloy and stainless steel housing are extremely robust and corrosion resistant.

Does The Internal Alloy Ever Need To Be Replaced?

No, it doesn’t.

The special alloy contained within SofterWater™ hard water conditioners is not a sacrificial anode, which means it does not corrode or lose molecules over time. This means it will technically be capable of lasting for decades.

In fact, there are commercial softening units installed by SofterWater™  over 20 years ago which are still effective today.

Will It Affect My Flow Rate?

No, it will not impact your flow rate as long as you select the appropriate unit for your water usage. 

SofterWater™ Hard Water Softeners – Testimonials

Hi Earl

I did realize how easy the scale remove.

I was working outside town this week and last night shower was amazing (in my own shower).

This SofterWater Conditioner is really amazing!”

– One small believer

“Well I am surprised. Quite frankly I had grave doubts — but here is what I have observed since installing your SofterWater Conditioner. As you know we are in rural Thailand.

Our well water delivered significant “lime deposits” which despite extensive “water softening” equipment would quickly block shower heads (one or two months) — coat tiled shower walls with scum — and make the shaving mirror in the shower opaque with deposits in about one week. Every week I would use an acid based cleaner and a nylon scouring pad to clean the mirror so I could shave. The shower walls were cleaned the same way.

I installed the SofterWater Conditioner aprox. March 2012 and immediately noticed that the mirror requires almost no cleaning whatsoever — simply a light wash over with water each few weeks or so. This amazes me!

I installed a new shower head (old one 70% blocked) at the same time as I installed the SofterWater Conditioner and now after 10 months — there has been no sign whatsoever of any scale blockage — no lime scale build-up in 10 months . None!

The tiled shower walls show very little scale or scum build up. Cleaning has been reduced by at least 80% — probably more.

I simply wanted to advise you of what I have found using the SofterWater Conditioner — and to thank you — a great product.”
