Abstract
An ice blocking apparatus for preventing ice blockage of a sump pump discharge line. The apparatus is mounted to an external wall of a building and includes a housing having lower and upper openings, a discharge line connection segment fluidly coupled with the sump pump discharge line, an expeller segment including lower and upper pipe segments fluidly coupled with discharge segment, and first and second doors pivotably mounted to the housing and covering the lower and upper openings of the housing. The lower pipe segment is fluidly coupled with the lower opening in the housing, and the upper pipe segment is fluidly coupled with the upper opening in the housing. When ice is not blocking the lower opening of the housing, fluid from a sump pump flows through the lower opening, and when ice is blocking the lower opening, fluid flows through the upper opening of the housing.
