- Have your water tested to make sure it is "hard." You local health agency can test the water for you, or you can contract out to a private laboratory. You can find listings under "water treatment companies" in the Yellow Pages.
- Purchase a water-softening tank. Select a single tank or a double tank, which can store salt (the softening agent) as well as water.
- Plan to have the water-softening tank installed by a professional.
- Install a piping bypass to send treated water to bathtubs, showers and washing machines. Prevent softened water from feeding outdoor faucets and drinking water.
- You can rent a complete water softening kit from companies that take care of installation and maintenance.
- People with high blood pressure or who are on a salt-restricted diet should not drink softened well water.
