Method of and apparatus for freeing a stuck valve in a valve assembly having a valve, a valve stem, and a valve operator connected to the valve stem. The apparatus comprises a tool having an enlarged head, an elongated shaft, and a bifurcated foot projecting at an acute angle from the elongated shaft. The bifurcated foot of the tool is placed abutting and straddling the valve stem, and in driving proximity to any enlargement of the valve stem, such as a return spring connector cap. An impact is applied to the enlarged head of the tool using a suitable striking tool such as a hammer. The impact is transferred to the valve stem, thereby unseating and freeing the valve.
