To cap off metal pipes, first, turn off the water supply and drain the pipe. Clean the pipe threads and apply joint compound or Teflon tape. Then, screw a threaded cap onto the pipe and tighten it with a wrench. For non-threaded pipes, use a suitable pipe cap and solder it in place or secure it with a clamp. Ensure a tight seal to prevent leaks.
