ABSTRACT:
A skimmer for a swimming pool includes a weir which extends outwardly from the skimmer face plate to divert a portion of the flowing pool water into the skimmer for subsequent treatment and recirculation. The weir is preferably attached to the skimmer face plate by a flexible lip formed around a peripheral edge of the weir which selectively snaps onto and off of a flange formed around the perimeter of the skimmer face plate. The leading edge of the weir extends outwardly from the pool sidewall to exert an enlarged field of influence on the water flowing along the surface of the pool to skim debris from the pool in less time than conventional skimmer devices.
