I need to tie-in a pvc pipe to an existing 4 in. pvc drain pipe. I plan to use a shielded fernco coupling. Is it okay to snake a pipe that has a fernco coupling? Will the snake tear up the fernco? The pipes are underground drainage lines that are outside of the house.

    There's always that possibility after many passes with an aggressive cutter head (like a spiral cutter or a serrated "C" cutter), but I believe the Code Gods would have something to say against installing this kind of fitting and so far they haven't. – ojait Nov 5 '15 at 4:15

    Typically the pipes will be nearly touching and the fernco just wraps around the outside of them. Do you anticipate a lot of fernco surface area showing to the inside of the pipes? – Joe Phillips Nov 5 '15 at 5:47
  • @Joe Phillips There will be a couple inch gap as I have to slide pipe back into the Y fitting's hub. – Laxmidi Nov 5 '15 at 15:01
