A chemical feeder for use in a water circulation system includes a body, a head attached to the top of the body, and a flow passage extending through the head. A portion of the water flowing through the flow passage is diverted into the body, where the water mixes with chemical tablets contained therein. A strainer is positioned inside the body and a stand pipe connects the strainer to the flow passage. Venturi forces within the flow passage draw the chemical solution from the body and into the flow passage, where the chemical solution mixes with the water flowing therethrough. It is possible to control the concentration of the chemical solution by controlling the flow of fluid from the flow passage into the body.

Pump

A safety device for use in a suction outlet assembly of a swimming pool, whirlpool, spa or the like is disclosed. More particularly, the outlet assembly has an opening therein in communication with a pump adapted to create sufficient suction for causing fluid flow through the outlet assembly and a cover mounted over the opening without substantially obstructing fluid flow therethrough. The safety device includes an obstructing mechanism for obstructing the opening when the cover is not properly positioned or affixed to the outlet assembly, whereby fluid flow through the outlet assembly is substantially prevented even if the pump is in operation.
