Abstract

A system for preventing erosion of metal objects in a swimming pool having chemicals therein includes a metal piece sacrificial anode, which may be of zinc. This metal piece sacrificial anode is contained within a tubular container and placed in a location along the swimming pool where it can be readily viewed. The metal piece sacrificial anode is removably supported within the container on the cover of the container, which is threadably attached to the container. The container is supported on piping through which water is supplied to the pool and to the interior of the container. The metal piece sacrificial anode is attached at one end to a an electrically conductive wire and to an electrically conductive copper wire or “bonding wire”, which runs around the pool and is attached to metal objects in the pool.
