How do I properly install and adjust the sink pivot rod in my bathroom sink?

To properly install and adjust the sink pivot rod in your bathroom sink, first, locate the pivot rod assembly underneath the sink. Connect the pivot rod to the lift rod and secure it with the retaining nut. Adjust the pivot rod length as needed to ensure smooth operation of the sink stopper. Test the sink stopper by lifting and lowering the lift rod to ensure it opens and closes properly.
