ABSTRACT:
A manifolded multiple wand spray apparatus with internal cleaning brushes and a flush valve that is activated when the rods carrying the cleaning brushes are rotated is disclosed. Valves that redirect the flow of water away from the manifold for a brief period during which spray orifice cleaning can be accomplished and an air intake valve that will admit air into the manifold to speed the flushing and create a negative pressure in the spray wands so as to draw obstructing materials into the spray wand during flushing is also disclosed.
