Water Jet Apparatus

Abstract

The present water jet provides an apparatus method and system for producing water flow within a pool or spa. A pump body contains a pump assembly with an impeller for aspirating water. In one embodiment an apparatus for producing fluid flow in a pool includes a pump body, an impeller for aspirating a fluid in the pump body, a jet nozzle for directing fluid aspirated by the impeller out of the pump body and a front cover attachable to the pump body wherein the front cover includes a fluid intake structure allowing fluid ingress from outside the pump body. The fluid intake structure includes ports distal from a front cover opening for the jet nozzle. The fluid intake structure is positioned to allow fluid flow ingress substantially parallel to the fluid flow egress from the apparatus.
