The system is designed for water with up to 25 grains of hardness per gallon. The conditioners are advertised as maintenance-free, but you do have to replace the filter media periodically. Puriteam guarantees Purhome Hard Water Conditioners for 5 years or 600,000 gallons.
Purhome softeners are sold through local dealers and online retailers like Amazon.com. You can also purchase through Puriteam’s website.
