Above the trap is a nut holding the stopper in place where the rod to
close the drain connects. Remove that and pull out the stopper and you
will likely find a hairball.
Bleach won't hurt anything but it does speed corrosion, there's a new
bleach with lye in it -clorox plus or extra or some such name. Works
even better on clogs.

Looks like most of my interior plumbing is pvc piping and wonder if
its safe to use a little bleach for a bathroom sink to loosen a clog?
It drains but slowly. I'll probably try a plunger first regardless
but I've been meaning to ask if the bleach is safe for interior
plumbing? My house was built in the late 90's if that matters.
thanks.
