Re: Drilling Holes in Floor Joists for plumbing
Are these solid wood joists or engineered lumber (I-beam style, laminated veneer, or oriented strands)? That makes a big difference.
Also, what are the dimensions of the joists, the length between supporting walls, and the center-to-center spacing?

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
