The PermaFlow Never Clog Drain ($39.95) is engineered to easily remove drain buildup before it clogs, eliminating the need for plunging, drain cleaners and disassembly. In addition, it’s transparent to allow for quick diagnosis of potential problems. An exterior dial activates an internal wiper to remove buildup and can be used as an emergency bypass option to enhance water flow and retrieve dropped items.
