The water sometimes can contain elevated levels of mineral ions, mostly calcium and magnesium, which makes the water hard. This has a negative effect on the plumbing system, will make your skin and hair dry and makes it difficult to form lather with soap. Travelers who spend a lot of time on the road, the RV travelers, may face these problems as well. Water softeners will reduce these mineral ions in the water, thus reducing some of these negative effects. After much searching, we conclude that the best RV water softener for most people is the Watts RV PRO-1000 OR M7002 10000 Grains Portable Water Softener.

The water softening process
As has been explained before, the classification between hard and soft water is dependent on the presence, or absence, of two highly soluble minerals, calcium and magnesium. These minerals have no adverse effect on the human body; to the contrary, these are part of the essential daily nutrients that the body needs. The problems that these minerals create lie elsewhere. Both of these minerals can form a deposit on the surfaces that they come in contact with, which may be in the plumbing, or your water heater, or decrease the effectiveness of soaps and detergents. According to an article on water softening the hardness in water is measured using one of two units. The first one is the parts per million (ppm) of calcium carbonate, which is equivalent to the concentration of dissolved magnesium and calcium. One ppm means that one unit of calcium carbonate is dissolved in one million units of water, which can also be equated to milligrams/liter (mg/l). The second expression that is used to measure hardness is grains per gallon (gpg) of calcium carbonate and this equals approximately 17 mg/l or ppm.
Classification of water hardness
|Classification||Grains per gallon (gpg)||Parts per million (ppm) or milligrams per liter (mg/l)|
|Soft||Less than 1.0||Less than 17||Slightly hard||1.0 to 3.5||17 to 60||Moderately hard||3.5 to 7.0||60 to 120||Hard||7.0 to 10.5||120 to 180||Very hard||Greater than 10.5||Greater than 180|
The amount of magnesium and calcium present in the water can be reduced by the process known as ion exchange. A physical and chemical process filters the water through an exchange media known as resin or zeolite, which typically is either a synthetic material or a natural sand-like material that is coated with positively-charged sodium ions. In water, the magnesium and calcium dissolves to form positively charged ions and the environment for the exchange of ions is created. When the water flows over the resin, it releases the sodium ions, which are readily traded for the magnesium and calcium ions. Hence the water that flows out is free of the calcium and magnesium ions, and is considered soft. Obviously the resin will not soften water indefinitely, there will come a point in time when all the sodium ions present on the resin will be expended, and the resin will no longer soften water. When this point is reached, the water softener will need to be run on an alternate cycle called regeneration. During this process, the resin is backwashed with a salt solution. The brine will not only replenish the sodium ions on the resin, but also take out the calcium and magnesium ions that may have been deposited. On completion, the water softener is ready for business again. Some water softeners will automatically switch to this process once it detects the low amount of sodium ions, in others the process has to be initiated manually.
Reasons for and against using soft water
As has been mentioned before, hard water will wreak havoc on the plumbing and will waste soap. According to an online publication from the College of Agriculture at the University of Kentucky minerals that cause hardness in water will create lots of problem for household appliances. Hard water will cause problems in almost every cleaning task that you might undertake, from laundering and dishwashing to bathing and personal grooming. Clothes that have been washed in hard water will look dingy and will feel very harsh and scratchy, hard water will cause the utensils to have spots on them and hard water will leave a residue on glass shower doors, shower walls and bathtubs. Hair that is washed in hard water will feel sticky and look dull. The performance on household appliances has been documented by some researchers at the University of New Mexico. The one-year study measured the energy consumption of six gas and electric water heaters in Las Cruces, New Mexico that have been in use from five to fifteen years. Half of each group used the untreated water present in the area which is hard. The other half exclusively used softened water. The results of the study showed that the heaters that were using hard water consumed more energy than the ones using softened water. This is not surprising because the accumulated scale is a poor conductor of heat.
Soft water is not without its problems, however. The calcium and magnesium ions that are dissolved in the water is what imparts a taste to the water, which some people like. According to an article on the risks of softened water there are some other more serious problems of using softened water. Soft water has a high sodium content, so it is bad for the plants once it starts accumulating in the soil, as it would not allow the plants to take in water and the plants would die of thirst. The extra sodium content is also not good for the lake or sea environment if the excess soft water is deposited there.
Maintenance of your water softener
If you suspect that you are not getting soft water, according to Plumbing Professors the first thing you should do is to check the control settings of the water softener system. Most of the softeners have an electronic control system that lets you set the time and duration of the ‘backwash’ cycle. So before you do anything else, you should check that the system is powered and the clock timer is set properly. The best time to do so is early in the morning when no one will be using the water. If that did not solve the problem, the next step is to check for problems in the unit that supplies salt to the softener. Salt will sometimes ‘bridge’ in the salt tank which happens when salt does not dissolve in the brine tank, which means that the resin is not getting cleaned as thoroughly as it should be, the end result being that the water that is coming out of the system is still hard. You can take a broom handle and push inside the tank. If a salt ‘bridge’ or ‘dome’ was present, it would cave onto itself. You can wait a day or two to see if the water coming out is now soft. If there was no salt ‘bridge’ or ‘dome’ the brine tank should be emptied of all the salt, paying close attention once you reach the bottom of the tank. A normally functioning system will only have some dirt and grime at the bottom. Instead if you have some mushy substance as the residue, that may be the problem. Once you have cleaned the substance, which is nothing but salt that has not dissolved in the water, make sure that you clean the tubes as well. If this does not solve your problem, then the resin inside the water softener unit probably needs cleaning. You would have to follow the instruction manual supplied by the manufacturer in order to do this properly. If the problem still persists, it is probably a good idea at this point to let a professional person handle this, unless you are comfortable working around electricity, gears, timers and pumps.

Top Pick: Watts RV PRO-1000 OR M7002 10000 Grains Portable Water Softener
The functioning of the Watts RV PRO-1000 Water Softener is very systematic and quite simple. The water softener unit measures 21 ‘ 9.5 ‘ 9 inches and weighs just 9 pounds which makes the unit quite capable to be carried around easily. The unit softens the water by absorbing heavy metal ions like calcium, magnesium and iron in the resin tank. The portable water softener unit utilizes a digital controlling system panel which will allow you to adjust the system according to your utility purpose. The system can work according to your needs. You can turn the system off when you are not using it, thus increasing the useful life of the resin inside the water softener unit. The Watts RV PRO-1000 is quite easy to set up. It has no moving parts and uses no electricity to operate. The water softener unit has been designed with brass and stainless steel fittings which mean that the unit does not require much in the way of maintenance. The 10,000 grain capacity of the water softener unit enables the unit to soften up to 5000 gallons of water before the resin needs to be recharged, and during the water softening period, the water pressure remains constant. The regenerating process uses 2 pounds of sodium chloride, which is the normal table salt that is available everywhere, and the regenerating process for the resin takes just 20 minutes to complete. This means that you do not need to carry around any specialist salt with you when you are enjoying your time in your RV, which is definitely very convenient and one less thing to worry about on your road trip. When you are done with using this system, it is very easy to empty it and store in compartments.
This unit will be of great service to the users who have a bit of knowledge on how a portable water softener works, and what the difference is between a whole house system and a portable system meant to be used in an RV, for example. The whole house system utilizes an automatic system of recharging the resin, while in the portable system, everything has to be carried out manually. If you see the ‘Y’ valve breaking, this is due to the very high water pressure that can be found in RV parks, with pressure reaching 80 psi rather than the recommended 45-55 psi, which can be definitely be damaging for the plastic ‘Y’ valve as it is not rated to carry such pressure. We would suggest buying a pressure reducer and set it upstream of the tank. The more hard water you run through the softener, the less water you can soften before the unit will need to be regenerated. But if you regenerate the unit regularly, the water softener unit will perform like a top line unit.

We were very happy with the general performance of this system. We tested this on hard water, where the reading came out to be 250 ppm, which is indicative of hard water. After we installed the system and performed a 5 minute flush, we repeated the test on the water coming in the RV, and the hardness reading of the water practically came to 0. In fact, the color of the test strip that he used on the soft water came out to be lighter than the lowest shade of the strips provided on the comparison bottles. We also witnessed a drop in hardness readings from 140 ppm to below 40 ppm after installing and using this system to soften the water coming into his RV. However the plastic hose fittings on this system is not very strong, especially if the unit tips over.
