The provided snippet details how to cap off a sprinkler head, effectively removing it from the system and preventing water flow from that location. It doesn't explain how to simply turn it off temporarily while keeping it in place. However, there are a few possibilities depending on your specific situation:
Here's a breakdown of possible scenarios and how to address each:
1. Temporarily Disabling a Single Sprinkler Head (Without Removing It):
- Problem: The sprinkler head is spraying in the wrong direction, creating a mist, or is otherwise malfunctioning, and you want to stop it temporarily.
- Solutions:
- Adjust the Nozzle: Many pop-up sprinkler heads have adjustable nozzles. Try turning the nozzle to reduce the spray distance or change the spray pattern to avoid unwanted areas. Some have a shut-off valve built into the nozzle itself, allowing you to stop the flow completely.
- Clean the Nozzle: Debris can clog the nozzle, causing it to spray erratically. Remove the nozzle and clean it with a small brush or pin.
- Check for Low Water Pressure: If water pressure is low, the sprinkler head might not be popping up fully, leading to poor performance. Investigate and correct low water pressure issues.
2. Permanently Disabling (Capping) a Sprinkler Head:
-
Problem: You want to permanently remove the sprinkler head from the system.
-
Solution (Based on the reference):
- Unthread the Body Cap: Unscrew the body cap from the sprinkler head body. This is usually done by twisting counter-clockwise.
- Pull Out the Riser: Once the cap is removed, you can pull out the internal riser assembly.
- Cap the Line: This requires capping the line that was feeding the sprinkler head to prevent leaks. You'll need an appropriately sized cap from a hardware store (usually a threaded PVC cap) and possibly PVC primer and cement, depending on the system's material. Turn off the water supply before proceeding. Apply primer and cement to the pipe and the inside of the cap, then quickly press the cap onto the pipe and hold it firmly until the cement sets.
- Important: The clip doesn't address how to cap off the line once the head and riser are removed, but that is the next necessary step.
3. Turning Off the Entire Sprinkler System:
- Problem: You want to stop all sprinklers from running.
- Solution:
- Locate the Controller: Find the sprinkler system controller. This is usually a box mounted on a wall in the garage, basement, or outside.
- Turn Off the System: Most controllers have a dial or buttons to turn the system off. You can typically select "Off" or "Rain Delay."
Important Considerations:
- Water Pressure: Always turn off the water supply before making any repairs or modifications to the sprinkler system.
- System Type: Sprinkler systems vary, so consult the manufacturer's instructions or a professional if you're unsure about any procedure.
- Local Codes: Check local codes and regulations regarding sprinkler system modifications.
