A hydrant main valve includes a main seal elastically deformable between a first state and a second state, such that a main valve assembly may be inserted into a main valve elbow without removable valve seats. A main valve assembly rotation lock engages a rotation block inside the elbow preventing rotation of the main valve assembly. A rotating operating stem extension moves a main valve bottom plate relative to a drain valve body, causing main valve seal elastic deformation.
