The most important part of the quality of any water softener is the salt that it uses. Special types of salt are used to help the machine soften the quality of the water. There are several popular types that many retailers carry. It is very important to only fill your machine with salt solutions that have been approved for water softener use. Trying other types might cause the machine to die a premature death.
The brine tank is of much importance to any of these machines. It is the part of the machine that feeds the salt solution into the holding tank. If a brine tank is not properly cleaned it could feed other unwanted things into your system. This could result in a number of negative effects. If the brine tank is not serviced properly and breaks this will cause your system to fail at softening any water that comes enters it.
