a reservoir fluidly connected to the tank and configured to hold a cleaning compound comprising a chemical compound and water from the water supply; and an actuator configured to control a flush cycle of the toilet upon a first activation, the actuator including at least one nozzle fluidly connected to the reservoir and configured to discharge an amount of the cleaning compound external to the tank upon at least one of the first activation or a second activation. ## Claims ### Claim 1 A delivery system for use with a tank, the delivery system comprising: a fill valve including a valve body and a water inlet configured to receive water from a water supply; a float configured to control an operation of the fill valve based on water in the tank; a container coupled to the valve body of the fill valve and configured to contain a cleaning compound; and a passage configured to transfer water from the fill valve to the container for mixing with the cleaning compound. ### Claim 2 (depends on 1) The delivery system of claim 1, further comprising: an outlet from the container to the valve body configured to transfer a mixture of water and the cleaning compound, wherein the passage is an inlet from the valve body to the container. ### Claim 3 (depends on 1) The delivery system of claim 1, wherein at least a portion of the container is transparent or translucent. ### Claim 4 (depends on 1) The delivery system of claim 1, further comprising: a cap detachably coupled to the container for access to a cavity for the cleaning compound. ### Claim 5 (depends on 1) The delivery system of claim 1, wherein the cleaning compound includes beads. ### Claim 6 (depends on 1) The delivery system of claim 1, further comprising: a metering device configured to dispense a predetermined amount of the cleaning compound. ### Claim 7 (depends on 1) The delivery system of claim 1, wherein the container is provided in line with the valve body. ### Claim 8 (depends on 1) The delivery system of claim 1, wherein the container is offset from the valve body. ### Claim 9 (depends on 1) The delivery system of claim 1, wherein the cleaning compound is gravity fed from container. ### Claim 10 (depends on 1) The delivery system of claim 1, wherein the container is integrated with the valve body. ### Claim 11 (depends on 1) The delivery system of claim 1, wherein the cleaning compound includes at least one anti-scale component. ### Claim 12 An apparatus comprising: a valve for a toilet, the valve including a valve body and a water inlet configured to receive water from a water supply; and a container integrated with the valve body and configured to contain a cleaning compound. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein at least a portion of the container is transparent or translucent. ### Claim 14 (depends on 12) The apparatus of claim 12, further comprising: a cap detachably coupled to the container for access to a cavity for the cleaning compound. ### Claim 15 (depends on 12) The apparatus of claim 12, wherein the cleaning compound includes beads. ### Claim 16 (depends on 12) The apparatus of claim 12, further comprising: a metering device configured to dispense a predetermined amount of the cleaning compound. ### Claim 17 (depends on 12) The apparatus of claim 12, wherein the cleaning compound includes at least one anti-scale component. ### Claim 18 A method of delivering a cleaning compound through a fill valve of a toilet, the method comprising: providing water from a water supply to a fill valve; providing at least a portion of the water from the fill valve to a container including a cleaning compound; mixing the at least a portion of the water with the cleaning compound; and providing the mixed water and cleaning compound to the fill valve. ### Claim 19 (depends on 18) The method of claim 18, wherein the container is transparent or translucent. ### Claim 20 (depends on 18) The method of claim 18, wherein the cleaning compound includes phosphate beads.
