    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?

    You roll wyes whey wyes need to be rolled. No part of a vent may run horizontal until it is 6" above the flood level rim of the fixture served so just rolling a wye and sticking a 45 in it may or may not be ok. If that 45 points vertical then yes. If it runs horizontal then no.

    for drains you can do anything you want with the "Y"s. It is only a vent that has to be rolled up, and even then it is not always a legal installation.
