May I ask some questions about water supply and drainage in hotel design?

If the first floor of the hotel is the lobby, and the second or third floors are standard-floor guest rooms, the pipe well should be arranged at the top of the first floor. At this time, the pipes along the top need to be redirected to horizontal horizontal pipes, and then Vertical is what you call "bending". Through interior decoration of hotels, the first-floor halls are generally decorated with suspended flat ceilings. The pipes in the suspended flat ceiling (but whether they are horizontal pipes, vertical pipes or "bent", such as water pipes, water pipes, fire pipes, air conditioning pipes, strong and weak wires, etc.) are invisible, so they do not affect the appearance. .
