Proposed drain and vent for bathroom remodel, UPC
I've read through a lot of different posts and I think I have came up with the correct venting and drain configuration. I'm not very good at drawing so hopefully it makes sense. My vanity, toilet and tub are all along the same wall that is about 10' feet long.
The main sewer line comes up directly under the wall behind the toilet. So the main line comes up and vents up through the wall behind the toilet. I think i need a double combination y-1/8 bend for the bottom drain and a san tee for the upper vent split.
One edit... the sanitary tee for the vent should be turned upside down. Not correct in picture
Thank you for spending the time to look at my question.
