Can I Use Rock Salt for My Water Softener? (Expert’s Advice)

Rock salt is widely available and cheap to buy, so you might be wondering whether you can use rock salt instead of other types of softening salt in your water softener’s brine tank.

In this story, we’ve answered the question, “Can I use rock salt in my softener?”.

We’ve also discussed the importance of the type of salt you use in your softener, and discussed the differences between water softener salt and rock salt.

Rock salt is okay to use in a water softener, but it’s certainly not the best of your options, and we don’t personally recommend it for this purpose.

Rock salt is technically a type of water softener salt because, unlike other salt types, you can use it in your water softener and it’ll serve its intended purpose during the ion exchange process.

But while rock salt can be used in a water softener in a technical sense, it’s important to consider its potential drawbacks.

Rock salt is less refined than other salt types (like solar salt or evaporated salt), which means it typically contains higher levels of impurities and insoluble materials.

Rock salt tends to be slower to dissolve, which can affect the brine production and regeneration process – further hindering the softener’s efficiency.
