In addition to considering the maintenance factors of a salt chlorinator, it is also important to realize that salt is a corrosive mineral. As such, use of a salt system may lead to the deterioration of certain materials if salt levels exceed the manufacturer’s limits. This includes, but is not limited to, natural stone (including flagstone, cultured stone, marbella, travertine, etc.), concrete (including Kool Deck, exposed aggregate, etc.), clay tile, grout, some metals, and some equipment components. Any damage to the pool and/or equipment resulting from salt is not covered under warranty.
