The short answer is: no, you shouldn't use pool salt in a water softener. While both products are based on sodium chloride (NaCl), the crucial difference lies in their purity and the presence of impurities. Using pool salt in your water softener can damage your system and potentially compromise your water quality. Let's delve deeper into why.
Why Pool Salt Differs from Water Softener Salt
Pool salt is significantly less pure than water softener salt. Water softener salt is specifically refined to minimize impurities like calcium, magnesium, and other minerals. These impurities, while present in small amounts in pool salt, can build up in your water softener over time. This buildup can:
- Clog the system: Impurities can prevent the resin beads in your water softener from regenerating properly, reducing its efficiency and potentially leading to premature failure.
- Corrode components: Certain impurities can contribute to corrosion of the internal components of your water softener, shortening its lifespan.
- Affect water quality: Although less likely, the impurities in pool salt can find their way into your softened water, potentially affecting its taste or even leading to mineral deposits in your plumbing.
What Happens if You Use Pool Salt in Your Water Softener?
The immediate effect might be subtle. You may not notice any problems for a short period. However, over time, the impurities in pool salt will accumulate and lead to the problems mentioned above. This can result in:
- Reduced softening efficiency: Your water won't be as soft as it should be, leading to problems like soap scum, hard water stains, and potential damage to appliances.
- Increased maintenance: You may need to clean or replace your water softener more frequently.
- Higher repair costs: Ultimately, using pool salt could significantly shorten the lifespan of your water softener, requiring costly repairs or replacements.
- Voiding warranties: Most water softener warranties specifically state that using anything other than approved water softener salt will void the warranty.
What Type of Salt Should I Use in My Water Softener?
Always use water softener salt, also known as evaporated salt or block salt. This type of salt is specifically manufactured and refined for use in water softeners and is designed to minimize impurities. You can usually find it at home improvement stores or online. Look for bags clearly labeled as "water softener salt."
Is it Cheaper to Use Pool Salt?
While pool salt might seem cheaper upfront, the potential for damage to your water softener and the associated repair costs far outweigh any short-term savings. Investing in the proper salt ensures the longevity and efficiency of your water softener, saving you money in the long run.
How Often Should I Replace My Water Softener Salt?
The frequency of salt replacement depends on several factors, including the size of your softener, the hardness of your water, and the number of people in your household. Check your water softener's manual for specific recommendations. Generally, you'll need to refill the salt tank every few months.
By using the correct type of salt, you'll protect your investment and enjoy the benefits of properly softened water for years to come. Don't compromise on quality—stick with water softener salt.
