Water softeners save money on appliances
Showerheads and faucets:
Showerheads on soft water maintained a brilliant luster and full flow. Faucets on softened water performed well throughout the study; nearly as well as the day they were installed. Showerheads on hard water lost 75% of the flow rate in less than 18 months. Faucets on hard water could not maintain the specified 1.25 gallons per minute flow rate because of scale collection of the strainers. The strainers on the faucets using unsoftened water were almost completely plugged after 19 equivalent days of testing.
In the study, dishwashers and washing machines were operated for 30 days and 240 completed wash cycles on soft and hard water sources. The units using soft water were almost completely free of any water scale buildup. As the report states, they appeared as if they could be cleaned up to look like new with just a quick wipe down. The appearance of the inside of units using hard water showed the need for de-liming and cleaning due to the buildup of scale and deposits.
