You should update this valve now that you are in there installing a new dishwasher.
The dishwasher purchase, "with installation" correctly does not include updating your plumbing.
It is extremely easy to replace this valve yourself. The pipe is exposed and in good shape and the old valve uses a compression fitting. Buy a Sharkbite quarter turn ...

You need two pipe wrenches - one for the pipe and one for the fitting so you don’t damage the other pipes.
However, I would likely go with a solder fitting to get to what you want if that is so tight.

It's definitely for a future bathroom. One of the 1.5" is going to be your vanity drain. Usually there's a 2" under the slab that you can bust out of install a shower or bathtub. The 3" is definitely for a toilet. One of the 1.5" pipes is going to be your vent.

Unless you have been deliberately avoiding the hot on your taps/valves while you had only cold water, you have probably run water though more than you think - but perhaps you have. Might depend on your valve types. I know I usually end up in the middle of my one-lever valves when the water heater is off, and at that point the water heater looks like a wide ...

It looks to be a 2" ABS pipe... you will need to source a longer ABS pipe and a coupler (2" to2"). Cut the existing pipe where its cleanest, clean up the area the coupler will go with light sandpaper, or a brillow pad, and put the new piece with the coupler on top. (so you will need ABS Cement as well, be sure NOT to use PVC cement)

As noted in a comment, I would suggest looking for a shorter tail piece without the fancy, tall nut (which, I'm sure, works very nicely for hand-tightening).
Normally the nut would be less than an inch tall, and it appears that a very short tail piece with a normal size nut would give you all the room you need to mate the two pieces up without ripping into ...

They mount on the wall (solidly into framing) and hooks on the back of the sink catch the pocket at the top of the bracket, typically. Gravity (which there is plenty of with a cast iron sink) does the rest.
It should be more obvious looking at the back the matching sink.

This looks like a crack in the T fitting:
If so you should replace it.

If you see nuts like these:

Then that indicates your plumbing is simply screwed together. (Note that you won't see the red (or sometimes translucent white) washer until you've taken the joint apart.) Unscrew the nuts, wiggle the pipes apart, and set the pieces aside. Odds are really good that you'll be able to ...

The quickest thing is likely to cut the pipe square with an angle grinder or recip saw, debur the pipe and use a furnco to convert from chrome to 1 1/4 abs.
It does look like the chrome goes to cast iron.

The "twisted" or bent aspect is the pipe it's connected to, not the valve.
If you are replacing with a new supply in a few months there's not a particularly strong incentive to replace it now, but it can be done.
There are various approaches to "no valve upstream" - one of the more common ones these days is to freeze a short section of ...

You'll need to open the wall and set the wall stub out at the proper level, patched the drywall, and mudded/sanded/painted to meet code.
You can't flex hose and a trap deeper than 4" can allow the trap to siphon.

A warm water net which is not used for months can become a breeding ground for a zoo of dangerous bacterias (especially for older people, people with reduced immune response etc.), among which legionellas are not the only kind.
Even after heating up (minimum 60°C for 10 minutes) and flushing the complete warm water net, the cold water lines could be still ...

Let me take this from the value proposition angle (I am assuming you own none of these)
A scoring tube cutter is about $15.
A simple metal file is $10 or less (or you can buy a de-burr/reamer tool for more than that).
A Sharkbite 3/8" ball valve itself (just shove it on) is maybe $12 (and it's as close to goof-proof plumbing as you can get)
A water ...

Updated Answer:
Issues with the posted arraignment (see last photo for number references):
The fall on the urinal drain exceeds the vent.
The vent serving the shower and urinal transitions to horizontal at a height that might be below the flood level rim of the urnial.
This connection is not required as the sink above would provide a wet vent for the lower ...

Late to the party, I know...
The only issue I see with it is that there is nothing between the shut-off valve and the tank itself. It appears to me that once you shut off the valve that the only way to remove the gas line from the heater is to remove the valve itself. This will leave you with an open gas line.
I would think you'd want a short piece of pipe ...
