摘要

A pool skimmer system including a skimmer housing and basket is disclosed. The skimmer housing includes a skimmer rim, a deck throat opening and a pool throat opening, a pump inlet port, a pool return port positioned at a first portion of a housing bottom, and one or more pump suction ports positioned at a second portion of the housing bottom. The basket is positioned within the housing and includes a basket rim engaged with the skimmer rim, one or more porous walls, and a seal plate extending from a basket bottom to the housing bottom. The seal plate is positioned between the first portion of the housing bottom and the second portion of the housing bottom to form a suction chamber. The suction chamber is adjacent the one or more pump suction ports and isolated from the pump inlet port and the pool return port.
