Abstract
An assembly of a drain plug for a dishwasher is disclosed, comprising a hollow stem portion and a drain plug body. A double O-ring is provided to seat and seal the ball body into a drain pipe, and to make a light, sliding fit with the interior of the drain pipe. The sliding fit guides the assembly during vertical movement and enables the assembly to maintain a vertical position without tilting. When the O-rings become worn, they are replaced, rather than having to discard the entire assembly.
