A traditional water softener will soften your hard water.  Prior to purchase, you should know what your hardness level and iron level is to ensure the system will take care care of the hard water as efficiently as possible.


Twin tank water softener softening systems control two tanks, meaning that there are two separate tanks of softening resin in addition to the salt tank. Twin tank systems soften your water using one tank at a time.

When one tank is regenerating, the second tank takes over the softening of your water. This provides the luxury of soft water 24-hours a day, 7 days a week. Twin softeners are great for large families and large homes or families that tend to use a lot of water.
You will realize salt (or potassium) and water savings because the system uses all capacity available of the tank in service, before switching to the second tank. Twin tank systems regenerate with soft water that keeps the system clean for optimum operating efficiency and minimal maintenance.
