Abstract
A pop-up drain includes a stopper assembly, a spring and camming members. The stopper assembly, the spring and the camming members are arranged within a pipe assembly. The spring biases the interaction of the camming members so that depression of the stopper assembly results in the stopper assembly sealing the pipe assembly. A second depression of the stopper assembly results in the stopper assembly moving into a position that unseals the pipe assembly.
