It very well might not be that easy--but if not then how is the DH any better off than the DW and 16 year old at fixing it
Either it is something relatively simple that a typical homeowner can figure out or else it isn't.
You'll note that I said the husband was not in the right to leave midway and to not explain a valid reason why, I also said that it was not such a huge issue as some have made it out to be. An older teen and an adult with a car at their disposal can certainly handle a few hours without the water on. This is an annoyance, but not life threatening.
Honestly, if it seemed that the fix could still be done that day, I can totally see not cancelling plans with others to stay home and get it fixed 3 or 4 hours faster.
I disagree on the either or thing My dad as well as my next door neighbor are very skilled in all things home repair related, and could repair things that some others can't but they are not professionals. However, there is no way that my DH or me could do the repairs that they do Not everyone can do everything. We all have different skills. I still say that if my DH left me lat home with no water and decided to go see a movie, he wouldn't be very happy for the next few days.
