Can this be reused?

Troubleshooting

The cap feels loose on the pipe

Ensure the pipe diameter is exactly 43mm and that there are no obstructions or debris inside the cap.

Slow drip detected after installation

Remove the cap, clean the end of the pipe thoroughly, and re-seat the cap to ensure an even compression seal.
