Abstract: An impeller vane includes at least one groove on a high pressure or working surface of the impeller vane to increase pump efficiency and reduce pump power requirements. The impeller vane includes a groove or a plurality of grooves formed on the high pressure surface of the vane. The grooves extend from a leading end of the vane to a trailing end of the vane. The grooves define ridges on either side of each groove that extend the length of the groove.

Abstract: There is disclosed a swimming pool skimmer basket handle capable of being attached to a swimming pool skimmer basket, in which the handle has a column that positions a grip of the handle above the top of the skimmer basket when the handle is attached to the skimmer basket. The column of the handle also positions the grip of the handle above the top of the water level in a skimmer well when the handle is attached to the skimmer basket and the skimmer basket is located within the skimmer well. The improved accessibility of the grip of the handle significantly minimizes the unpleasantness associated with removing and cleaning a swimming pool skimmer basket. There is also disclosed an improved reversible weight for a skimmer basket. The reversible weight is capable of being attached to a skimmer basket in two configurations. A number of alternate embodiments of the invention are also disclosed.
