I noticed a leak in the laundry area, inside the wall (the new carpet was wet at the bottom of the wall). I didn’t want to let that linger and decided to just remove the drywall and fix things myself – and install a new washing machine box and connection valves while I was at it. Problem is: this is all copper tubing and I don’t have the tools nor have I ever soldered copper before. Well, nothing like learning on the job (and once again: that book is great)…
Don’t forget to also get a Solder Heat Shield! I didn’t realize how important it was until one of the stud started burning…
I was a little too stressed to stop and take pictures, so stock images is all you will get.
high heat and wooden stud… hmm, something to think about 
Washing machine valve box 
I’d recommend to go for a MAP torch rather than just Propane (not hot enough)
