This is the floor drain near my gas furnace. It handles the condensate line. I'd like to reconfigure it to also accept a water softener drain line, possibly by installing a larger bowl. I'm not sure how to open it up though. What type of drain is this, and how would I go about removing it from the pipe it's glued to?
The two areas that appear to be screw heads are not. They seem to be just molded into the plastic. I suspect that they are holes for screws to secure a cover that's no longer present.
