Sure! It's cramped under sinks and a little hard to work under there, but
why not? You might look into compression fitting the new shut off if the
pipe is clean and undamaged. Less dangerous than sweating a new fitting
in - no flames.

For the record, my first plumbing project - besides replacing the fill valve
in the toilet - was replacing a water heater. No different than eating an
elephant: you do it one bite at a time.

I've got a leaky hot-water pipe joint that feeds the dishwasher.
Leaks from the tee where the shut-off valve is, under the sink. Is
this a good choice for my first-ever DIY plumbing attempt? I'm plenty
handy with wood and electrical, but haven't attempted plumbing. I've
got the flux/solder/etc, and have watched a zillion shows and read a
zillion books, Whaddayathink? Can I just resolder the thing, or
does it have to come apart and go back together again?
