About the water softener system. Service When the water softening system is providing soft water, it is called “Service.” During service, hard water flows from the house main water pipe into the water softening system. Inside the water softening system resin tank is a bed made up of thousands of tiny, plastic resin beads. As hard water passes through the bed, each bead attracts and holds the hard minerals. This is called ion-exchanging. It is much like a magnet attracting and holding metals. Wat

Breaking a Salt Bridge Sometimes, a hard crust or salt bridge forms in the salt storage area. It is usually caused by high humidity or the wrong kind of salt. When the salt bridges, an empty space forms between the water and salt. Then salt will not dissolve in the water to make brine. If the brine tank is full of salt, it is hard to tell if you have a salt bridge. Salt is loose on top, but the bridge is under it. The following is the best way to check for a salt bridge. Salt should be loose al

About the water softener system. Cleaning the Nozzle and Venturi Assembly A clean nozzle and venturi is needed for the water softening system to work properly. This small unit makes the suction to move brine from the salt storage area to the resin tank during regeneration. If it becomes plugged with sand, dirt, etc., the water softening system will not work and you will get hard water. To get to the nozzle and venturi, remove the water softening system top cover. Be sure the water softening sy

Care and cleaning of the water softening system. Checking the Salt Storage Level and Refilling Brine (salt dissolved in water) is needed for each and every regeneration. The water for making brine is metered into the salt storage area by the water softening system valve and control. However, you must keep the tank supplied with salt. When to refill with salt: Check the salt level a few weeks after you install the water softening system and every week after that. Refill when the brine tank is fro
