3-How to fix drain plug leak:

Fixing a leaking drain plug is simple and quick.  Use silicon caulk from your neighborhood hardware store. First remove the entire drain plug assembly. Then generously apply the silicone caulk all over the inside and outside of the drain hole. Reinstall the drain plug and then apply more silicone caulk around all the edges. Wait at least 24 hours and this will solve the leaking drain.
