I have an unfinished basement, and I installed a redirector for my sump pump output so it can be drained to the sanitary sewer during winter months (and yes, I'm paying for the right to do so, and I'm following the rules :)). I installed a wye in the vertical drain pipe, and I needed a way of reconnecting said pipe after introducing the new fitting. To do this, I took a section of the 3" pipe, glued it to the top of the wye, and joined it to the original pipe with a Fernco fitting (specifically, this guy).
The question: is it safe to leave the Fernco fitting in place and enclose it in a wall when I go to finish the basement?
