The pipe that goes from my internal overflow to my sump has been hot glued into place. Where should I cut the pipe? Would it be better to cut on the blue section in the picture or cut on the thread of the bulkhead? Or maybe can I just unattach the grey hose and unscrew the bulkhead? The grey hose isn't glued in. I want to cut it in a way that it can be easiest to reinstall later. (Sorry for the basic questions. This is my brother's tank and he's not here to help me out. I don't know very much about sumps honestly.)
Also, once I cut the pipe, I can just unscrew the bulkhead and take it out right? There's a pipe inside the overflow that attaches to the other side of the bulkhead in the pics.
