Abstract: A piercing nozzle is disclosed having first and second elongated, hollow members connected at a connection that allows fluid to be communicated from the first member to the second member. The first member has a hose connector for attachment to a hose. The second member has a plurality of holes positioned proximate an end that penetrates a wall. An anvil is connected to the second member proximate the first end of the second member, and a piercing tip is connected to the second end of the second member. In use, the nozzle may be swung like an axe to penetrate a wall. Water or other fluid passes through interior cavities of the nozzle from the second end of the first member, through the first and second members, and out the holes in the second member, on an opposing side of the wall.
