My drain pipe in my unfinished basement is close to the ceiling which makes it hard to change things. I know that the drain in my basement is wrong right now and I am trying to fix it. I only have one attachment of ABS (1 1/2") to the main cast iron drain pipe and adding another one isn't really an option. I have a kitchen sink with a dishwasher attached to it and a basement laundry tub pump that all needs to be attached to the same drain. The laundry tub pump says that it does not need to be vented or have a trap. I have posted pictures of two options that I am thinking of. What is the best way to do this?
