Hello everyone, i'm getting ready to start a bathroom project in my basement. I will be breaking the floor our and running the drain pipes under the floor into a sump pit. I know that I will need to run a vent for the sink and the sump pit itself, which is no problem. However I'm not sure about venting the shower and the toilet. Someone told me I would be able to use the sump pit as an indirect vent for the toilet and shower. I want to do this right since I will be breaking up the floor to run the plumbing, and once it's done, it won't be easy to fix mistakes. I created a sketch of an idea of how I wanted to run the drains and vents, could you please let me know if this is correct. I already contacted my local municipality and do not need a permit to do the work, however I do want it to be correct.
