What kind of salt do you recommend using and do your softeners also use Potassium Chloride in place of salt?
We recommend buying salt for your water softener that is very clean; around the 99.5% salt content and up. All softeners can use Potassium Chloride in place of salt. Potassium Chloride pellets tend to melt or break up when it gets wet, sometimes forming a “bridge” inside the salt tank, so we recommend filling the Brine tank only halfway or a bit more when using Potassium Chloride, so you can easily monitor it going down inside the tank after the unit regenerates.
The most common method of refilling the brine tank with water is the post fill method that is programmed into the control valve. If your water softener is on post refill, we recommend using crystal salt. Crystals will dissolve only to a point to where the is a 100% saturation of salt to water. This means the water will not hold anymore salt. The crystals will not fall apart like pellets can and will not clog the bottom of your brine tank. Crystals will allow the water to pass through them more readily than pellets that have fallen apart at the bottom of the brine tank.
If your water softener is on a pre-refill setting we recommend using pellets. When the system is set to pre-refill the brine tank or brine compartment will fill before regenerating begins. This method of pre-fill leaves the brine tank or brine compartment empty so, there is no water for the pellets to set in thus reducing the opportunity for the pellets to fall apart and clog up the brine pickup valve.
