I am planning on putting a bathroom in the basement. My ejector pit currently services a floor drain into which runs condensate from the central air as well as water from the central humidifier. I would like to install a toilet, sink, and shower. Do these each need separate connections to the pit, or can I run one 3 or 4 inch drain for the toilet directly to the pit, and tie in the proposed 2 inch lines from the sink and shower into the larger toilet line?
Also, regarding venting, can all these tie into the existing vent from the pit?
Your help is greatly appreciated.
