Toilet /Shower DWV
My bathroom has a two foot 3" drain into the main 4" stack, this drains the toilet, the toilet is the highest fixture and vents into the main stack.
I am adding a shower,
I can vent the shower with a 1/1/2" existing vent about 3 feet from the toilet and within 1' of the shower trap.
Can I insert a 3-2-3 Y fitting between the the toilet and stack to serve as the shower drain or do I need to tap into the main stack after it goes vertical. This tap in will lie between the toilet and the stack, essentially before the toilet stack vent pipe.
Seattle codes.
Thank You
