Rusted screw removal

Does anyone know how to remove a rusted, broken off screw inside a bathtub overflow plate? I’m hoping to replace the plate but I need to get this screw out first…

How can I take this shit off? I tried everything for two days

Can I repair this myself?

Ran over this sewage pipe connector outside of our rented home. The landlord has Covid and is generally very difficult to deal with. Curious if I could replace it myself. If it’s possible to fix this on my own without too much trouble, how might I go about that?

Need help to find this part

Where can I order replacement of 3/4 inch and 1.5 inch connector for C901 pipes. Please help. Thanks !

Any advice?

Leaking flush assembly

The refill tube is dripping about 2 drops a second. That's like 172,800 drips a day. . .any way to stop this from drip drop dripping? Pressing up on the float does not stop the dripping.

What part is this bidet water line? I want to replace it because it’s a bit moldy inside and can’t clean it well enough.

Toilet either doesn’t flush all the way or lets all the water out of the tank?

I have a Fluidmaster adjustable flapper and it’s brand new. No matter what setting I move it to, I can’t get the right flush. It will either let all the water out or will barely flush at all. Even when just moving from a 6 to a 7 I have that dramatic of a difference. The chain has about 1/2 in of slack and this was installed by a plumber during a partial tank rebuild. The chain isn’t getting caught under the flapper. Is the flapper defective or could I have another problem?

Can I put an additional (and separately controlled) showerhead here? What do I need to buy?

Just moved into a new apartment & is this normal? The top of it is attached to the water heater but the bottom looks like this (not connected to anything)
