Abstract
A device for use in a swimming pool structure, the swimming pool structure including a circulation system having a piping assembly and a pump for cyclically communicating water through the piping assembly. The device includes an insert coupled in fluid communication to the piping assembly, a piston carried within the insert for reciprocal movement between a lowered position and a raised position in which the piston is above the insert, a nozzle in the piston is unobstructed, and the piston is in one of a plurality of indexed orientations. The piston rotates to an adjacent indexed orientation in response to reciprocation between the raised and lowered positions in response to the cyclical application of water through the chamber. Upper and lower engagement assemblies prevent rotational movement of the piston with respect to the insert in the raised and lowered positions of the piston.
