ABSTRACT:
A flow-through or in line type trap primer adapted to deliver a first metered spurt of water through a primer flow passage to a trap upon the initiation of flow in a supply line, and a second metered spurt of water upon the termination of such flow. A reaction disc in the main flow passage causes a stem to translate between two positions, and means cooperating with the stem cause the primer flow passage to be closed at said two positions and open as the stem moves between said positions. Manual as well as automatic priming is provided for.
