I just moved into an apartment and the shower does not drain well. It floods above my feet every time i shower. I've tried running vinegar down it after showers and this sort of helps, but eventually i need to use a plunger on it to get it to drain, since it will stop draining entirely after a few days.
I dont know if this is contributing, but there is a built in stopper in the drain, and im wondering if i can remove this safely? What is it called?
