Srew turns but won't come out
IÂm seeking help trying to figure out why a screw will turn but wonÂt come out.
The screw is inside the handle of an exposed shower valve. It needs to be removed in order to get the handle off so that I can replace the ceramic disc valve (dripping shower). The screw is about 1 inch inside the base of the handle, so you have to peer into the handle base to see it. After some difficulty I have figured out that the screwhead is a combo Phillips slotted. I have the right size screwdriver; it is a Phillips since I couldnÂt find a combo screwdriver. ItÂs supposed to work.
The screwdriver will fit into the head slots and you can see the screw turn. IÂm being careful to turn only counterclockwise. After about a thousand turns (really) the screw has loosened about 1/8 inch. As best I can figure out the screw is screwed into the ceramic disc valve (that part is under the valve shroud so you canÂt see exactly what the screw is attached to).
Why isnÂt the screw coming out? What can I do?
