Abstract
A fire hydrant having a hydrant valve seat assembly positioned between the flanged lower end of the hydrant barrel and the flanged end of the hydrant shoe. The hydrant valve seat assembly and the hydrant valve element may be retained with the hydrant shoe when the hydrant barrel is removed and replaced or the hydrant valve seat assembly and the hydrant valve element, when in the closed position, may be retained with the hydrant barrel when the hydrant shoe is removed and replaced from the barrel. The fire hydrant includes an improved valve seat ring and seat ring housing, both of which may be made of brass so as to provide easy removal of the valve seat. The hydrant is provided with an improved drain valve facing strip for cooperating with the drain passage when the hydrant valve is open.
