In most cases, what is the best way to quickly stop the flow from a single sprinkler head?

• A. Close the branch line valve
• B. Replace the bulb or link
• C. Insert a sprinkler wedge
• D. Install a replacement head

Answer: (C)

When you need to stop water to a single sprinkler head quickly, using a sprinkler wedge is the most effective approach. A sprinkler wedge is a simple device placed around the head that blocks the water from flowing through that particular head while leaving the rest of the system pressurized. This isolates just one head, enabling rapid control of water flow without shutting down an entire branch or affecting other heads. This method is fast and reversible, so you can remove it once the issue at that head is addressed and restore normal operation. In contrast, closing a branch line valve would cut off flow to the whole branch and impact other sprinklers; replacing the bulb or link won’t stop flow through the head; and installing a replacement head doesn’t address the current discharge from the head in question.
