1. A method of disinfecting a valve configured for use as part of a water delivery system, the method comprising: activating a heating element that is configured to heat a body of the valve to a temperature sufficient to kill organisms that may be present on internal surfaces of the valve, wherein the heating element and the valve are configured to be provided within the water delivery system, and wherein the valve is a mixing valve, wherein the step of activating the heating element comprises utilizing a controller associated with the valve to activate the heating element, and wherein the controller is located in a recessed area of a body of a plumbing fixture housing the mixing valve. 2. The method of claim 1, wherein the step of activating the heating element causes the body of the valve to reach a temperature of at least 60 degrees Celsius. 3. The method of claim 1, further comprising holding the body of the valve at the temperature for a predetermined amount of time. 4. The method of claim 1, wherein step of activating the heating element is performed at a predetermined time after the valve is used. 5. The method of claim 1, wherein step of activating the heating element is performed at a predetermined time. 6. The method of claim 1, wherein step of activating the heating element is performed at predetermined time intervals. 7. The method of claim 1, further comprising deactivating the heating element and then actuating the valve to direct a fluid through the valve to flush the valve. 8. The method of claim 1, further comprising preventing the valve from operating to allow a fluid to pass therethrough while the heating element is activated. 9. The method of claim 1, wherein the heating element is a resistive wire heating element. 10. The method of claim 1, wherein the heating element and valve are within a body of a faucet. 11. The method of claim 1, wherein the mixing valve includes a mixing chamber defined by at least one of the internal surfaces of the valve. 12. The method of claim 1, wherein the heating element and valve are within a body of a showerhead assembly. 13. A method of removing organisms from a mixing valve that is included within a plumbing fixture, the method comprising: operating a heating element extending through a portion of the mixing valve such that a temperature of a water contacting surface within the mixing valve reaches a temperature greater than approximately 60 degrees Celsius, wherein the step of operating the heating element comprises utilizing a controller associated with the mixing valve to operate the heating element, and wherein the controller is located in a body of the plumbing fixture that houses the mixing valve and the heating element. 14. The method of claim 13, further comprising flushing the mixing valve to purge the mixing valve of organisms. 15. The method of claim 13, wherein the step of operating the heating element causes the body of the valve to reach a temperature of at least 60 degrees Celsius. 16. The method of claim 13, further comprising holding the body mixing valve at the temperature for a predetermined amount of time. 17. The method of claim 13, wherein step of operating the heating element is performed at a predetermined time after the mixing valve is used. 18. The method of claim 13, wherein step of operating the heating element is performed at a predetermined time. 19. The method of claim 13, wherein step of operating the heating element is performed at predetermined time intervals. 20. The method of claim 13, further comprising preventing the mixing valve from operating to allow a fluid to pass therethrough while the heating element is operating. 21. The method of claim 13, wherein the heating element is a resistive wire heating element. 22. The method of claim 13, wherein the heating element and valve are within a body of a faucet. 23. The method of claim 13, wherein the heating element and valve are within a body of a showerhead assembly. 24. A cleaning routine for a plumbing fixture, the cleaning routine comprising: raising the temperature of a water contacting surface within the plumbing fixture to a temperature sufficient to kill organisms on the water contacting surface using an electric heater provided within the plumbing fixture; andpreventing the plumbing fixture from allowing water to pass therethrough during the step of raising the temperature of the water contacting surface;wherein the plumbing fixture is selected from the group consisting of a faucet, a shower head, and a plumbing fitting. 25. The cleaning routine of claim 24, wherein the water contacting surface is within a valve located within the plumbing fixture. 26. The cleaning routine of claim 25, wherein the valve is a mixing valve. 27. The cleaning routine of claim 26, wherein the electric heater extends through a body of the mixing valve. 28. The cleaning routine of claim 24, wherein the temperature is greater than approximately 60 degrees Celsius. 29. The cleaning routine of claim 24, wherein the water contacting surface is a waterway within the plumbing fixture. 30. The cleaning routine of claim 29, wherein the water contacting surface is part of a liner provided within the plumbing fixture. 31. The cleaning routine of claim 30, wherein the heater is in contact with the liner. 32. The cleaning routine of claim 24, wherein the step of raising the temperature comprises utilizing a controller operate the heater, and wherein the controller is located in a body of the plumbing fixture that also houses the heater. 33. The cleaning routine of claim 24, further comprising holding the water contacting surface at the temperature for a predetermined amount of time. 34. The cleaning routine of claim 24, wherein step of raising the temperature of the water contacting surface is performed at a predetermined time after the mixing valve is used. 35. The cleaning routine of claim 24, wherein step of raising the temperature of the water contacting surface is performed at a predetermined time. 36. The cleaning routine of claim 24, wherein step of raising the temperature of the water contacting surface is performed at predetermined time intervals. 37. The cleaning routine of claim 24, wherein the electric heater is a resistive wire heating element. 38. The cleaning routine of claim 24, wherein the plumbing fixture is a faucet. 39. The cleaning routine of claim 24, wherein the heating plumbing fixture is a showerhead assembly.
