I am finishing my basement bathroom. We just bought this house and it as all the plumbing and the ejector basin in place. I need to buy a pump and hook up the sewage lines and vent lines. I know where the sewage line goes but I am not sure about the vent. I have attached images of my set up. There is a clear written label on the Ejector drainage pipe but not on a pipe for the vent. I am thinking is the other one they have nicely capped off but not 100% sure. Any thoughts? Look at the pictures.
