What Is An RV Water Softener and How Does It Work
RV water softeners are essential to install and use in a recreational vehicle. It does wonders by ensuring the prevention of soap scum, rust buildup, and dry skin and water spots. With one, you can be sure to protect your plumbing system from the buildup of rust and accumulation of minerals, including calcium and iron that might degrade its function. Added bonus can include those coming with a filter because it can reduce the bad odor and taste in the water.
How does it work? Different systems work in different ways, too, in order to get rid of the harmful effects of hard water. These systems include salt-free systems, salt-based systems, reverse-osmosis systems and magnetic systems.
It is one of the methods of softening water, one also used in desalinating saltwater. Here, the hard water will be forced through a fine line membrane. When it does, the impurities will be left on one side and the water on the other side. RO systems are also used in above sink water filters and under sink systems.
Here, hard water will have to pass through a magnetic field, resulting in the reduction on the effects of hard water. Such systems are smaller in size versus other types of water softening systems.
Salt-based water softeners
They’re the most common are said to be most effective of all water softening systems available. It makes use of an ion exchange process. How does it work? Here, hard water will pass through a mineral tank filled with resin beads charged with sodium ions.
Generally, they come with a brine tank that washes and cleans hard water minerals trapped inside the resin tank, a process called regeneration. This process will start again once a cycle is completed.
In this system, the minerals in hard water are not removed but are only changed in another form. In some cases, they are crystallized. So without even saying, the minerals are just transformed or converted into hard crystals, so they won’t bind to a surface.
Why Do You Need an RV Water Softener (Benefits)
There are many benefits to using a water softener in your recreational vehicle. You should not go camping with your RV without it. For one, hard water is often the common problem in many campgrounds all over the US.
If you don’t use a water softener, your plumbing system will be damaged because of the mineral buildup. For more explanation, check out the following for the benefits of using water-softening units.
Easier appliance and cookware maintenance and cleaning
Coffeemakers and washing machines as well as silverware and other kitchenware can have stains and spots due to calcium, heavy metals and other minerals present in hard water. If water is unconditioned, it will be harder to clean them up.
The same goes regarding maintenance. Without an RV waters softener, your entire plumbing system will be harder to maintain because the elements in hard water will spread in your entire RV water system.
And when unattended, your system will not only be harder to maintain but it might also suffer from irreversible damage requiring replacement.
Longer appliance lifespan
Hard water can degrade the function of your appliances as well as shorten their lifespan. If you’re looking to extend their lifespan to serve you longer, you should definitely buy a water softener that can help you achieve this goal.
A water softener will remove hard water minerals and heavy metals, which would otherwise ruin the function and later on damage your water appliances, such as coffeemakers. To prevent it from happening, you should consider softening water using one of the water softeners we have featured here.
Water heater efficiency
The buildup of minerals, including calcium and magnesium in the water heater can degrade its function. With too much buildup, you will later notice that it works slower than it normally does.
By using a water softener like On the Go with the On the Go water softener regeneration, you can improve the function of your water heater.
Efficient plumbing system
Using a water-conditioning unit, you can have a more efficient plumbing system that stays clean and free from trace minerals and heavy metals. With an improved plumbing system also follows money savings because you don’t have to spend on frequent repairs, too.
Your appliances will work more efficiently with a water-softening unit. It is because they don’t suffer from the building up of elements, including iron, calcium and magnesium. As our appliances will work more optimally, we don’t also have to worry about increasing energy bills.
How We Picked
Our team used several factors to review each product we have featured here. As there are many water softeners on the market, we find it uneasy to select the top choice without checking on some characteristics.
Easy and quick regeneration
When picking the best water softeners for RV, we also believe that the unit should offer quick and easy access for regeneration. For one, the unit should have large mouth opening and requires no disassembling when regenerating.
Just as we noted earlier in this guide, there are four basic systems in softening hard water. But for the most part, we recommend either a salt-based or a salt-free based system for the purpose of softening water to go into our RV.
Capacity and Weight
When choosing a water-softening unit, we must look for one that is lightweight, ensuring that it is highly portable for carrying around. For one, we can use it not only in our RV but also in the house and in the car. It can help us in softening water for use in washing the car, filling soft water to our tubs and taking a shower.
That is why we have to look for a portable choice that also has a large capacity. In our featured products above, we have chosen those with high capacities, as we believe these are also the practical choices other than smaller capacity models.
For the most part, we suggest choosing a standard unit with 8000-grain capacity and weighs at most 18lbs. But if you have larger water softening requirements, we recommend picking one weighing about 30 lbs with 16,000-grain capacity.
When it comes to the accessories coming with the water softener, we also consider the carrying handle. It is what can make the unit more portable to carry anywhere. That is why we have chosen those that offer us with good handling ability.
There should also be inlet flow control. We find it useful for quick and easy regeneration. And when it comes to eliminating water spillage, we find those having transportation and storage adapters useful.
We also picked based on the base of the unit. It should be stable and wide to keep the product secure in place. Some of the models may also come with a wall bracket for more support. Nevertheless, pick one that has a sturdy base when selecting an RV water-softening unit.
We recommend using only water softeners that make use of high quality exchange resins to ensure of the best results. That is why we carefully picked those models with premium exchange resins. We do hope that you can choose one from those we have listed in the above reviews.
There you have a few factors to consider when choosing the right water softener for your RV. Again, check on the exchange resin, system, capacity, weight, handling and base, to name some. Finally, compare and weigh your options well to pick the right recreational vehicle water softener.
Frequently Asked Questions
Q: What is the regeneration time?
A: The regeneration time usually takes between 85 and 90 minutes for its automatic regeneration cycle. Nevertheless, we recommend that you check the user manual coming with the model you have purchased just be sure on how much time is needed for the regeneration cycle to complete. For example, if you’re using an On the Go water softener, read and understand the On the Go water softener instructions for specific regeneration time reminders.
Q: How to regenerate RV water softener?
A: It varies from one model to the next. In most cases, it will depend on the type of unit you have. Thus, you should follow the user manual for the best results. On the other hand, there are brand models that require you only to turn it on in order to start the regeneration. These are the units with the built-in knobs.
Q: Does RV water softener go through a lot of salt?
A: Water softeners require salt to function, so yes, it does require going through much salt. But remember to use only the correct amount of it so that your water-softening device will function correctly. In all cases, make sure that salt is at a consistent level, so figure out the right pattern based on the model you have chosen.
Q: Is it possible to use potassium instead of salt?
A: Yes, you can. It is a good alternative to salt even if more expensive. Remember though that it can melt easily when wet. That said it has the tendency of causing a bridge development within the tank. For that reason, the experts suggest filling just more than the halfway mark when using potassium chloride.
Q: How to maintenance your RV water softener?
A: Each RV water softener may require different maintenance instructions. It varies from model to model or maker to maker. At the very least, you should refer to the manual for the best results.
In general, most tanks will require regular maintenance, such as cleaning the tank and refilling the salt pellets as you may read in a Watts RV Pro-1000 review. On the other hand, there are units that do not require much maintenance or tune-ups.
