How is a sprinkler wedge used to stop flow from an activated sprinkler?

A sprinkler wedge is a tool specifically designed to halt the flow of water from an activated sprinkler head in emergencies or during repairs. The mechanism of using two wedges to pinch the flow is critical for effectively stopping water discharge without causing additional damage.

When two wedges are pushed together from opposite sides between the orifice and the deflector, they create a seal that effectively blocks the water from being expelled. This method ensures that both sides of the orifice are addressed, providing a more secure and effective means of stopping the water flow. The alignment and tension created by the opposing wedges are crucial in maintaining the blockage and preventing any accidental overflow.

Using this technique minimizes the risk of injury or further damage during the intervention process. It also allows firefighters or personnel to quickly address sprinkler activation in a controlled manner, facilitating a safer environment for both responders and occupants of the building.
