<human>: What's an argument for and against the use of a water softener?
<bot>: For: 
1. Water softening removes minerals that cause hard water, making it easier to clean with less soap.
2. It also reduces scale buildup in pipes and appliances, which can lead to higher utility bills.
3. It can reduce chlorine taste and odor in tap water, which some people prefer.
4. Hard water is more corrosive than soft water, so softened water may help protect plumbing components from damage.
5. A softened water supply will have lower mineral content, reducing the risk of certain health problems associated with high levels of minerals in drinking water.
