    How to vent plumbing in basement bathroom
    I built a bathroom in my basement... shower, vanity, and toilet. I had to buy a pump from Lowe's designed for this renovation. For it, I had to build a raised floor for the installation. The pump is designed to attach to where the toilet sits. My main sewer drain is about 5' up the wall behind. The pump was plumbed to drain to it. My question is the venting for it. I tried a studor vent, but it won't work, because of no air getting in for the pump. It won't let the toilet flush. Am I going to have to run pvc and tie into the main vent to my shower upstairs? Thanks.

    That will vent your fixtures. However the pit vent MUST BE DEDICATED and not connected to anything. I have put up a image of ejector pit venting. If wet venting's allowed in your area you may connect the shower drain to the lavatory drain and let it be wet vented by it.

    Yes your answer and image helped. But, are you saying that I can't tie in the pit vent with the vent that runs up behind my upstairs shower then through the roof?

    That's exactly what I'm saying.
    The vent servicing the ejector pit must be a dedicated one.
    The lavatory vent must be separate from the pit vent. The reason for this is while the lavatory and fixture vents just pull outside air into the system to relieve the suction caused by draining waste the pit vent must push air out while the fixtures are discharging into the pit it must also pull air in while the ejector pump's pumping the pit out. It's not good plumbing practice to introduce pressure into a venting system designed to operate under suction.
    Run a separate vent on the pit.
    Good luck, Tom
