    Vent question

    My first plumbing project and I could use some help. This 10x10 bathroom has 2 sinks, 1 toilet and 2 shower drains. Is the single vent on the main sewer sufficient or do I need an independent vent on any of these fixtures?

    Are these drain lines installed correctly?

    I was curious if the laundry drain lines and vents are installed correctly in these photos. Eventually, a sink for a 1/2” bath will be added, but I wanted to see if anything needed to be fixed before going any further.

    Is this allowed/how to fix?

    I was told that even though this ties into the main stack, it is not allowed due to it being on a 45 degree angle + it will create a siphon. Is that correct?
