I recently purchased a house with an unfinished basement. I ve been thinking about finishing the basement and installing a bathroom down there. My question is how would I go about doing that. The waste line runs underneath the cement floor. I think it is made of cast iron but I'm not exactly sure. My plan is to break the cement open and to run a waste line to the toilet and shower and connect it to the main waste line. How would I connect them and how would I seal up the floor. Please help.

Hey Bobby,

It's not quite as simple as all that. Every fixture that has a trap MUST br vented out the roof or revented back into a dry vent. I'll tell you what I can do to help and the information you must provide me before I can do it. I can lay the bathroom group out according to Standard Code and instruct you on converting from cast iron to PVC and how to vent the group but I'll need a diagram showing me the area you wish the fixtures to go, the type of fixture you wish to install and above all I need to know exactly where the main is, Where it exits the house, (hint! At the cleanout) and the location of the stack coming down from upstairs.
I'll look forward to hearing from you. Cheers, tom
