Patent ID: 7655116

Claim:
In a system for preventing erosion of metal objects in a swimming pool having water therein and said water having chemicals therein, said system having a metal piece sacrificial anode in an electrical circuit, an electrically conductive bonding wire which preferably is made of copper running around said swimming pool and attached to said metal piece sacrificial anode by an electrically conductive wire and to the metal objects in the pool, an electrolytic circuit formed by said metal piece sacrificial anode, said electrically conductive wire, said bonding wire and said metal objects the water in the pool, said electrolytic operating to remove ions from said metal piece sacrificial anode such that erosion of said metal objects is prevented, and a water pipe running around said swimming pool containing supply water for said pool, the improvement comprising, in combination: a transparent container in which said metal piece sacrificial anode is contained; said container having a removable cover, said metal piece sacrificial anode being attached to said cover; means for mounting said container on said water pipe; and means for connecting said container to said water pipe water to receive water therefrom.
