I am plumbing a bathroom over a crawl space. There is a shower and toilet on one wall and a lav on the opposite wall. I would like to run down the middle of the room with a 3" main come out with a 3 to 2 combi to the shower then roll a 3 to 2 combi up so the 2" lav drain / wet vent comes in to the top half of the 3" then continue on to the toilet with the 3" The distance from the rolled combi is not over 6 ' is this acceptable? Both the toilet and the shower would be vented by the 2 " lav drain
