I have been working on my rough in. Everything is going good I just have one question. On my vents I rolled up my wye and placed a 45 on the end and ran the pipe over to my stud wall. On my drains should I also roll up my wyes and place a 45 and then send the arm out to its desired location. Basically I have my 3" main line coming in a 3" wye that runs towards my toilet and shower drains a wye that sends a 2" arm out for my shower and the pipe continues about 2' until the 90 for the toilet. Should I roll the wye for my shower arm?
