I see ads for “No Salt” needed water softeners. How do they work without using salt?
Many dealers will advertise a no salt water softener/conditioner. Any brand of water conditioner can be operated without using salt. This is done by using a salt substitute, potassium chloride. It generally more expensive compared to regular salt (sodium chloride), and can be difficult to find in some areas. Also, it is generally recommended you increase the salt setting on your control valve by about 10%, when using a salt substitute.
