I have this style tub drain and can't figure out how it works. Does it simply block the flow of water when lowered? Or is there something more complicated happening?
My tub has stopped draining and when I removed the cylinder from the drain tower it came right out, but this did not affect the stoppage. I wonder if it should be attached to something, but can not see into the tube well enough.
I should add that I had been trying to unblock the drain and used a plunger on it. So there is a possibility that I plunged the clog(s) into a more blocking state, but I suspect that the pressure of the plunger interfered with something mechanical, because the water isn't receding at all, even after some hours.
