When you have a water softener, you are already aware of the importance of salt in the operation of the whole system. However, salts are not all alike. This is a question that many homeowners are struggling with: Which between pellet salt and crystal salt should I use? The selection of the appropriate type guarantees the efficiency of your system and the cleanliness and softness of your water. Let us provide a comparison between both types in detail so that you can make the best choice for your home.
It would be helpful to understand the workings of your water softener before comparing pellet and crystal salt. Minerals such as calcium and magnesium are present in hard water. These minerals eventually accumulate in the pipes and lower the functionality of appliances.
A water softener replenishes its resin beads with salt. These beads entrap hard minerals and substitute them with Sodium ions. Once the beads get saturated, the system is flushed by the salt solution (brine), which cleans the system and refills it to allow it to run another cycle. This process will not be functional without the correct salt, and the problem of hard water will occur once again.
Pellet salt is formed by crushing small, rounded grains of acceptable salt into small pellets. These pellets are slowly and evenly dissolving, and this prevents the formation of bridging or clumps in the brine tank.
Pellet salt has additives that tend to clean the softener. These additives eliminate iron formation, sediment, and clogging. Pellet salt also makes the water flow in the softening process smoother because of its homogeneous shape.
Pellet salt will be convenient when your house has an average or high amount of water consumption, or when your water softener is a big one. It also works well when you have a newer and more advanced system.
Solar salt or crystal salt is a salt that is produced by the process of natural evaporation. Seawater or brine evaporates under the sun to leave behind crystals of salt. Such crystals are less dense and dissolve quickly compared to pellets.
Crystal salt contains fewer additives. It is also usually more natural and clean, which is an attractive feature of environmentally conscious homeowners. But due to its rapid solubility, crystal salt may lead to bridging in specific systems. Bridging is the process whereby salt can form a hard crust in the brine tank, and this has blocked the water accessibility to the lower layers.
Crystal salt may be more appropriate in the case of low water consumption or a softener with a low frequency of regeneration. It is also cheaper than pellet salt in most areas.
Now we can divide the principal differences between pellet and crystal salt:
It depends on the situation you are in. Take into account the water hardness, type of softener, and level of use in your house.
Pellet salt is the more appropriate choice in case your household has a high consumption of water or you have hard water containing deposits of iron. It maintains your softener clean and efficient over time. Pellet salt also prevents issues such as bridging and mushing, making the process smoother.
Nevertheless, crystal salt offers a practical and inexpensive option when you use your softener occasionally for moderately hard water. It is effective in smaller systems and homes that consume low water.
Magnificent Plumbing & Rooter frequently recommends that householders test the water hardness and make a choice. This is a basic test that shows how many minerals are in it, and it can also tell what type of salt will give better results.
You should maintain your system regularly, even with the right salt. Bridging salt is one of the common problems, in which the salt develops a solid layer over the water. To avoid it, sometimes handbreak the salt or pellet salt in case of crystal salt.
Salt mushing is another problem where the salt is a thick sludge at the tank base. This has the potential to clog the system and make it less efficient. It is always a good idea to clean your tank of brine once or twice a year, depending on how much water you use and how much minerals are available.
Moreover, salt of known brands of good quality should be used. Low-quality, cheap salt is usually impure and will damage the resin bed and also reduce the life of your system.
The effects of both the crystalline and the pellet salts on the environment are different. The manufacture of pellet salt is more energetic since it involves further processing. Crystal salt, on the other hand, is a natural product formed as a result of the sun’s evaporation, and it is therefore more environmentally friendly.
Nevertheless, the efficiency of pellet salt may decrease the number of regeneration cycles, and thus save on the consumption of water and energy in the long run. Then, the decision is the most appropriate one according to your values, sustainability, or performance.
The decision between pellet and crystal salt can be an easy one to make, but it directly influences the quality of your water and the life of your softener. In case of uncertainty, refer to an expert to help determine the requirements of your water softener.
Magnificent Plumbing and Rooter deals in treatments of water, like installing softeners, servicing them, and providing advice on salt. Expert engineers examine your type of water, level of hardness, and system demands so that they can perform and last longest.
You can choose between the convenience of pellet salt and the purification of crystal salt as nature dictates, but either way, your system will be effective and your water will be soft all year long. It is essential to continuously check the operation of your softener and refill the salt tank regularly to ensure the high quality of water in your house.
