In one of the bathrooms, there is a sink plug that is actuated by a
handle between faucets. It works, however, it resists removal. I want
to remove it because I want to clear the drain with sulfuric acid (the
drain is plugged and I had great success with S.A. with other sinks).
So... How do I remove this plug without breaking anything?
There's a good chance that when you remove the sink plug you'll find that
hair has plugged the drain and that the plug causing the problem will come
out with the drain stopper.
Many of these kinds of drain stoppers can be removed simply by twisting them
about a quarter turn and lifting them out. On some stoppers it depends on
how they were initially installed - one way they're removable by the
twisting method, the other way the stem has to be removed in order to get
the stopper out.
Sulfuric acid is good for dissolving hair plugs. If you use sulfuric acid
and don't clear the plug, be sure to tell the plumber that you used it.
Sulfuric acid likes to dissolve hair but it also likes to dissolve skin.
