Often a mystery to homeowners, we’ll learn about how a water softener works and more importantly, how to reduce their salt usage. But before we do we’ll see why as Today’s Home Remodeler host Stuart Keith heads to the Madison Metropolitan Sewerage District treatment plant to meet with Kathy Lake. We’ll learn about their treatment process and how too much salt is entering their facility through wastewater coming from water softeners. We’ll touch on the environmental impacts of too much salt in our freshwater ecosystems and also what it could mean if nothing is done about it. We’ll then head to the Plumbers Local 75 Training Center to find some solutions and meet with instructor Bob Lanphear to learn how water softeners work, when they should be replaced and ways to reduce their salt usage.
