Shower knob seized up. It's a single valve that mixes hot/cold water, won't turn.
Take off the knob and cover plate to get to the valve. stupid little copper stem insert in plastic thing, looks just like this:

Go to lowes to grab one, turns out they come in all shapes and sizes and I need to remove my existing one to measure it up against the new one to make sure its the right one. ok NP just gotta shut off the water to the house to pull this one, i'll do this quick so i'm not without water all day.
and the mother fucking plastic piece of shit just snaps in fucking half. That's why it was broke, that's why it seized up to begin with, it snapped in half and only that first little bit pulled out, the rest is lodged deep as fuck in my pipes and I have no idea how to get it out. I think maybe to drill it out but that will destroy the insert and potentially i'll drill through pipe or some other piece in there that i'm not supposed to. Ok maybe ill take a flat head and just chisel it out in pieces? I've gotta start banging on this damaging who knows what maybe breaking shit i'm not supposed to. either option will result in the destruction of the piece and leave me not knowing what size I need to go buy and replace it. At this point i'm so frustrated and I know that I don't know enough to not completely destroy my fucking shower so it's time to call in the professionals.
So that's how I ended up without water on a sunday waiting on a plumber to come bend me over for many hundreds+ dollars for what will end up being about 5 minutes worth of work on an emergency call to replace a shit ass piece of plastic garbage.
