    Drain and vents

    Proper venting of bathroom

    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?

    Trying to move bulkhead - issue with structure in the way of pipes.

    I have a question here regarding my vent. In the pictures, there is the main vent (on the right) which ties into the toilet and vanity vent (on the left). This is currently installed with 45 degree adapters at the top, presumably (I thought) so that they would not cut too much out of the top...

    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.
