Figuring out the sewer layout has been a bit more difficult than anticipated. One of the most difficult is communicating the completed design. The diagrams of each plumbing layout just didn’t have enough accurate information. All the tees are actually 45 degree wyes because tees are against code used in a horizontal position. The direction of the pipes is all horizontal and it is difficult to imagine them in 3D space.
Took another stab at communicating the pipe layouts and this helped solidify the requirements for all of us. There is something missing from these drawings though. There is an existing sink in the garage and that drain is not showing.
