ABSTRACT:
A skimmer assembly for use in swimming pools in which a skimmer housing is provided with a skimming inlet and a drain inlet for receiving water from a pool. An outlet is also provided for connection with a vacuum source for discharging water from the housing. A floating weir is disposed in the housing for regulating the amount of water entering the housing from the skimming inlet and a filter basket is disposed in the housing with its open end communicating with the skimming inlet and a wall portion communicating with the drain inlet. An adaptor member and a cover plate cooperate with said basket for selectively controlling the flow of water from said skimming inlet to said outlet. The basket is adapted to attain a plurality of positions in the housing for regulating the flow through the drain inlet to the housing, and a sealing assembly is provided on the weir and the basket for sealing off flow through the skimmer inlet when the level of water in the pool falls below a predetermined value. The weir is adapted to accommodate an adaptor assembly for attaching a vacuum hose to the assembly for vacuuming selected portions of the pool under the vacuum created by the aforementioned vacuum source. A valve relief mechanism is provided on said weir for permitting water flow from said skimming inlet in the event the drain inlet becomes blocked when the weir is in its sealing position.
