With advanced Wi-Fi technology and a range of features, the Whirlpool WHEC46 Wi-Fi Water Softener System brings best-in-class water softening to households of 1 to 6+ people. The free wi-fi management app allows homeowners to see critical alerts like low salt levels and continuous water flow events, and provides valuable daily, weekly, monthly and yearly information about your household water usage. Plus, the optional Whirlpool Remote Water Shutoff Valve (WHECSV) gives you the power to respond to potential leaks while away. Whirlpool water softeners are among the most salt-efficient units in the industry. 6th Sense technology learns your water usage patterns and reduces waste by calculating the amount of salt and water your family needs. That’s less salt to buy, carry, and remember.
