installing vents

Author: ownzzjoo (CA)

My mind is going crazy. I could use some advice please. Start off with the crawl space opening. On the right side of the opening there is a 4 inch stub out(abs) for the drain. The toilet will go on the left side of the joist. There will be toilet in the center, shower on the right, and vanity on the left. How should I vent this system with the window in the way of the vent? I really could use a couple of new ideas. thanks

Author: packy (MA) the window is not in the way of the vent. you will have one 2 inch vent behind the vanity and one 3" vent inside the 2 x 6 wall the shower valve is in.

Author: hj (AZ) CA doesn't require a 3" vent as long as he has adequate vent sizes, especially if this is a additional bath.

Author: packy (MA) I see a 4" plastic pipe coming in thru the foundation. makes me think a 3" vent stack would be required.
