    Cool - thank you…

    Do you happen to know why so many diagrams seem to have loops? (like this):

      Without that extra loop, it’s possible that flushing the toilet will suck the water out of your sink trap.

      I know absolutely nothing about professional plumbing, but wouldn’t that sink loop need to be there to act as a drain and vent for the sink? I don’t think the main vent stack would work for that without it
