I'm adding a new 1/2 bath in an empty space. The waste pipe runs horizontally (with proper slope) out through what used to be the outside wall of the house, into the attic space above an addition on the front of the house. It then goes straight down through a closet, then will go at an angle into the main horizontal drain pipe for the house. The main horizontal drain pipe for the house has a toilet at the far left end, then the main vent stack, then drains from a sink and bathtub, then after that is where my new pipe will connect with a Y fitting. After that it continues horizontally a ways, then down and out of the house. I can take pictures of that if there are any concerns, but that part seems pretty straight forward to me.
Here is how I laid out the pipes through the floor joists in the new bathroom:
I can connect the 2 vent pipes together in the attic, and then just run one 2" vent pipe up through the roof, right?
Any problems with the way I have everything connected?
