Begin by shutting off the water supply and draining the sink. Use a basin wrench to remove the old drain assembly, clean the mounting surface thoroughly, apply Teflon tape to threads, install the new pipe with pipe cement, wrap the connections with Teflon tape, and test for leaks before restoring water flow. Proper alignment and tight sealing prevent future drips.
