The best place to locate a water softener is in a basement, garage or utility room near a main water line, electrical outlet and a drain. The area should be level, dry and not subject to freezing temperatures.
Water softeners are used to remove the minerals from hard water. They should be placed in an out-of-the-way location with all of the necessary hookup requirements. This is often near the water heater. There must be enough space left around the unit to allow for a person to move around to maintain and service it. A water softener should never be installed outdoors or in direct sunlight.
