The Upgrade replacement grinder pump from Environment One Corporation is engineered to fit into virtually any grinder pump wet well. Universal design allows easy drop-in conversion, ready to connect. All solids including plastic, rubber, fiber and wood are ground into fine particles, allowing them to pass easily through the pump, check valve and small-diameter pipelines. The grinder is designed not to jam and for minimum wear to the grinding mechanism. It comes with a self-contained level control system, eliminating float switches. 518/346-6161; www.eone.com.
