How Do I Figure out...

How do I figure out if a wall is a supporting wall or not. I've googled it but cannot follow the beam into the foundation or any of the other tricks they mention. I have a 3 foot wide "separator" wall in the bathroom. I would like to see if it's possible to knock it down... give a big guy some more room in there.

Also, as a sidenote, how hard is it to move plumbing and stuff a few inches laterally?

P.S. The snarky "call a conctractor" posts, while cute/funny, don't help. HA. I'm stressed enough about money, can't really pay a remodel person, but if someone can walk me through what to do, I can buy a few beers, etc.

Take a picture or 2 so we can see the wall in question.

Moving plumbing can vary. Supply side (water lines) are much easier than waste side, because sewage and drain lines need a constant slope and you're screwing with the angle by moving them, and you can't really relocate the main stack.

1st floor or second floor? Can you get to the attic? Full span trusses? Age of home? Any chance of tracking down some plans from the bldg dept or builder?

Some remodels are easy, others can be a nightmare.

My Uncle's 1st wife took a sledge to the wall in the kitchen while he was at work...when he got home, she had the sledge against a truss "holding it up". 8 foot celing remodeled to a 6 foot ceiling. :)

Do you have attic above? If so, that can help.

Highly unlikely that a 3 foot wide wall is a bearing wall if it is in the interior (not abutting an exterior wall).

With PEX, moving supply plumbing is pretty easy now. Good plumbers are re-piping entire houses in a day. Sanitary sewer is still a bit harder, but it usually is a case by case endeavor.
