Hello! Long time lurker, first time poster. I've exhausted my searches trying to figure out what to call this cap I've found during a basement finish, so I'm looking for some additional help. I'm trying to set up a test with an inflatable test-ball to make sure my shower pan and associated drain lines will hold water. I located the cleanout, installed by the builder when the home was built (2010) and pulled off the above-ground cap to discover a screw-in cap that I haven't encountered before. Markings on the cap are sparse, but do include "tighten to hand tight + 1/8 turn", and that's about it, that I can see. This leads me to believe that it is threaded in, but no amount of turning on it will get it to budge. I don't have a proper wrench or tool for it, and don't know what it's called, which is why I need a little assistance.
There may be some sort of brand logo, it looks like it says "UPC" or maybe "UPVC", but it's a little hard to make out. The surrounding pipe is 6" pvc, and the cap itself is about 2-3" below the level of the concrete around it, about 8" down in the surrounding pipe. I assume it connects to a 3" or maybe 4" line below that. I've included shots from directly above, looking down, from behind the framed wall, and a shot of the pipes prior to the concrete being poured. This is probably fairly simple, but I've never encountered it, and I don't want to just tear the cap out, to discover that I've caused some other problem by doing so.
If someone can help me identify it, or tell me the name of a tool that might help me get it off (I've improvised a couple of tools out of lumber, but all of them break when I apply torque to try to turn it), I would be so grateful. Or, I suppose, if it's just a 6" cap that I can tear out and replace with a square-drive cap, that would be good to know as well.
Thanks!
