Overview
This article provides a comprehensive guide for identifying and repairing leaks in runways and reservoirs. Leaks in the system can affect water flow and plant growth conditions, so it's important to address them promptly. Whether the issue is with bulkhead fittings, the runway water level, or a damaged liner, following these steps will help you efficiently resolve the problem and maintain optimal system performance.
Bulkhead Leaking
At Aluminum Runway:
- Tighten the Nut: If the bulkhead is leaking at the aluminum runway, try tightening the nut located at the bottom of the bulkhead. This may be enough to stop the leak.
Out of Threaded Connection:
- Drain Water: Empty the runway of water before making repairs.
- Apply Teflon Tape: Remove the threaded connection and apply 3 wraps of Teflon tape in a clockwise direction. This will create a watertight seal when the connection is reassembled.
Runway Leaking
- Check Water Level: Ensure that the water level in the runway does not reach or overflow the black trim.
-
- If the water level is too high, adjust the standpipe or balance the flow to each runway to ensure proper distribution and prevent leaks.
How to Patch a Leak in the Runway Liner
- Remove Plants and Rafts: Begin by removing all plants and rafts from the affected runway to clear the area.
- Close the Ball Valve: Shut off the water flow by closing the ball valve.
- Drain Water: Remove the drain standpipe and drain all remaining water from the runway.
- Inspect the Runway Liner: Carefully inspect the liner for any scrapes, holes, or punctures that could be causing the leak.
- Clean and Dry the Area: Clean the area around the leak and ensure it is dry before proceeding with patching.
- Prepare the Patch: Cut a piece of Gorilla Patch Tape (or other suitable patch material) to a size at least 1 inch larger than the hole to ensure full coverage.
- Apply the Patch: Firmly press the Gorilla Patch Tape over the hole or puncture, ensuring it adheres well to the liner.
- Replace the Drain Standpipe: Once the patch is securely in place, replace the drain standpipe.
- Adjust the Ball Valve: Open the runway ball valve and fine-tune it to ensure the water flows evenly across the runway.
- Check for Leaks: After refilling the system, check the area for any visible drips or leaks.
Tip: Allow the system to sit for at least 12 hours before doing a final check for emerging leaks, as some leaks may take time to show up.
Summary
This leak repair guide covers common issues in runways and reservoirs, such as bulkhead leaks, improper water levels, and damaged liners. By tightening bulkhead fittings or applying Teflon tape to threaded connections, you can address most bulkhead leaks. For runway leaks, ensure the water level is properly adjusted and apply patches using Gorilla Patch Tape to seal any holes or punctures in the liner.
Always allow time for the patch to set and thoroughly check for leaks before putting the system back into operation. By following these steps, you can maintain a fully functioning and leak-free irrigation system.
