Abstract:
1. An apparatus for automatically maintaining a predetermined water level in a body of water, wherein the apparatus is communicatively coupled to a circulation system for the body of water by a pipe, said apparatus comprising: a float valve assembly employed as a means to restrict the flow of supply water into a float chamber of said apparatus, wherein the float valve assembly includes a float valve with an armature to actuate said float valve; a ball check valve contained within the float chamber, the float chamber being configured to isolate the pressurized water in the circulation system of the body of water from the water in the float chamber of the apparatus and, after pump operation has ceased, to allow the passage of supply water from the float chamber of the apparatus to the circulation system of the body of water; an elastic outlet conduit connected to the apparatus, wherein the elastic outlet conduit is employed as a means of aiding in extraction of a ball within the ball check valve from a ball seat of the ball check valve, wherein the ball comprises a polymide material of a density near that of water, and wherein said extraction is caused by a momentary suction at an outlet of the float chamber as said elastic outlet conduit returns to its undisturbed shape after pump operation has ceased; a float assembly fully residing within said float chamber and removably coupled to said float valve assembly, the float assembly comprising:
