Maybe someone has come across this in the past and has a fix.
In one of my return fittings I had the standard stopper inside it. The kind that has the plastic coming up on 2 sides, and you stick a screw driver in between them and use them as leverage to turn. Well mine must have been old and brittle because when I went to go take it out, the plastic on one side broke right off. So then I tried using a wrench on the other side and it broke right off too.
So now it's stuck in there and I'm not sure how I'm gonna get this out. Tried a large pipe wrench on the outside, but that wasn't working. Anyone have any advice? Maybe it's happen to you and you've got a trick to get it out when this happens?
