I'm in the process of adding a laundry sink to the basement, where there was one years ago.
Problem is, the floor drain drains into the septic tank. The stack, where other sinks, etc from above drain, is not close, and there's no place to locate a sink near it.
Is there a way I should vent the sink drain? I can run a line up overhead that ties into the kitchen sink drain pipe, which leads to the stack, but this still strikes me as not exactly working right.
Any comments on what others have done in similar situations are appreciated.
