Answers: if you are putting a current bathroom in what i would do is this. if your stool is close to the sink you will want to vent the sink through the roof and where on earth the sink drain drops through the floor tie it into to the stool using a 3x2 tee. that will vent the stool and the lavatory. also if your shower is not inwardly 5 ft of your lavatory drain then you will also requirement to vent the shower seperately. just run a vent pipe up the wall and tie it surrounded by in the attic beside a tee to the lavatory vent. consequently underneath the floor what you will do is go from your ptrap from the shower into a nouns on the vent pipe then out of the bottom of the nouns to your drain line. that will properly vent your shower. if the shower is in 5 ft of the drain line later dont worry roughly venting it. hope this help
You can use a tee or y,to connect 2in pipe to basic drain and run up through wall and out on top of roof you will obligation a rain proof bonnet and flair seal for roof mount,Be sure you connect after toilet nouns and also sink connection will necessitate vent.
