Hi, I'm doing a basment bathroom. Toilet, shower and vanity. Will be running a ventline off the line from the vanity. Does it matter how long or how many elbows you get in a ventline run? It will be a 2in vent line.I have to come up the wall, 45 elbow, across the room, 45 elbow,around an air vent, 45 elbow, down, 45 elbow and tie into 3" sewer line(wet vent)( also that 3in sewer line is about 2ft above the vanity height)... its pretty much impossible for me to run it up and out the roof. Total run of about 25-30 ft... just wonder about all the elbows I will have in it... do I have everyone confused yet?
