Block salt is an essential part of the TwinTec S4 water softener and is used during the softener’s regeneration stage when flushing out all the unwanted minerals. To keep your water softener running smoothly you will need to refill it with TwinTec block salt roughly every two weeks, however this may vary due to household size.
