A water heater wrench adapter that comprises a rotating adapter and receiver. The rotating adapter is disposed within a receiver in light interference fit, wherein the rotating adapter is frictionally engaged by the receiver to permit rotation of the rotating adapter within the receiver. The water heater wrench adapter is utilized by frictionally engaging the insulator profile with the rotating adapter, thereby securing the water heater element within the rotating adapter. The hex nut of the water heater element and the hex extension of the receiver are aligned and the hex end of a water heater wrench is disposed to engage the combined hex nut and hex extension. Thus, the water heater wrench can then be utilized to either hold the water heater element in position for installation in a water heater or remove and retain the water heater element from the water heater.
