I decided in the modeling of my plumbing/pipe systems to use general plumbing due to the sporadic nature of rainfall throughout the year to Jasper Ridge. Because of this I think that general plumbing is just simply easiest to use. In my first floor, I have two medium sized gender-neutral restrooms in my exhibition space. Each restroom includes three toilets (water closets), one urinal and two sinks. I found some challenges originally with orientation as well as figuring out how to align the pipes into the correct levels, but eventually figured it out!
