To cap a small pipe, first, turn off the water supply to the pipe. Clean the pipe’s end, ensuring it’s free from any debris. Select a cap that matches the pipe’s material and size, such as a push-fit, threaded, or solvent weld cap. For push-fit caps, simply push the cap onto the pipe's end until it’s firmly in place. For threaded caps, wrap plumbing tape around the pipe’s threads before screwing on the cap. For solvent weld caps, apply the solvent cement to both the pipe and the cap, then join and hold them until set.
