Block salt comes in several sizes ranging from large 50 lb blocks down to 5 lb bricks. We do not recommend using any size block salt in your water softener for several reasons.
- First, block salt does not provide the necessary salt dissolution required to efficiently regenerate the water softener's resin. What this means is that the resin in the water softener does not get cleaned or rinsed properly, resulting in hard water.
- Secondly, the salt sensor is designed to measure the amount of salt in the tank, based on a leveled load of salt. With block salt, the sensor may not accurately read the quantity of salt, which could result in running out of salt or unnecessary “low salt” alerts from the water softener.
