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)

Shower valve substitute?

I remodeled a bathroom and due to lack of communication between me, my contractor, and plumber, I ended up with a less than ideal situation. Most of it I’ve pivoted and worked through. However, he’s saying I need a Delta Monitor 13 Series Shower Valve. Every fixture in the bathroom is brushed gold, and they only make this valve in chrome. It sounds like he’s already installed the valve on the other side of the wall. Is cracking some tile and redoing the whole thing the only option now? For context, it’s a ceiling rainhead shower, plumbed with an additional line for a horizontal shower and wand combo.

Dented water heater

I got a new water heater from Lowe’s and after my installer completed installation, I noticed this large dent. Is this cosmetic or should I be concerned about the performance of the tank or potential leakage?
