Ok, we might be putting a full apartment in a basement. Can the bathroom be tapped into another bathroom that is directly above? Or what other options do I have for this, also We want to put in a dishwasher possibly and a kitchen sink. Any ideas on all this. And Where in the lines does it need to be vented?Laso, how to I find out where everything runs into the sewer line, cuz we are putting a seweage ejector thing in, so Ineed to find out where this will have to get connected. Thanks
