Abstract
A sewage pump priming system including a sewage pump disposed above a sump for holding sewage to force sewage from the sump through a sewage discharge conduit, a priming chamber receiving sewage from the sewage discharge conduit to be partially filled with sewage to a level above the sewage pump and the sewage discharge conduit, a vacuum pump communicating with the priming chamber for sucking sewage into the priming chamber to prime the sewage pump and a gas relief conduit providing a passage for gas above the level of sewage in the priming chamber to the sewage discharge conduit at a position downstream of the priming chamber such that the priming chamber is utilized to prime the sewage pump and to remove gas from the sewage pump priming system.
