Frequently Asked Questions
Softener sizing depends on your water hardness level and household water usage. A water test will determine your hardness in grains per gallon (GPG), and your dealer will factor in the number of people in your home and daily usage patterns. The 10 GPM model suits most 1-3 bathroom homes, the 15 GPM fits 3-4 bathrooms, and the 20 GPM handles larger homes with 4+ bathrooms.
No. Water softeners exchange hardness minerals (calcium and magnesium) for sodium ions, but the amount of sodium added is very small — typically 12-30 mg per 8 oz glass depending on hardness, which is far less than a slice of bread. Most people notice water tastes cleaner and smoother, not salty.
A water softener significantly extends the life of your water heater by preventing scale buildup on heating elements and inside the tank. Hard water scale acts as an insulator, forcing your water heater to work harder and use more energy. Studies show that softened water can improve water heater efficiency by up to 29% and extend its lifespan by years.
The Smart Softener can handle low levels of clear-water (ferrous) iron, typically up to 2-3 PPM. For higher iron levels or ferric (visible) iron, we recommend pairing it with a dedicated iron filter or choosing a system specifically designed for well water iron removal. Your dealer can test your water and recommend the right configuration.
