No offense intended scoob. I’ve read enough of your postings to know that you’re not lacking in skills. I do enjoy staying busy with projects around the house, so that’s what I do. :)
The pipe is simply a pass-thru for the sewer hose, it won’t have anything actually connected to it. I put it there because I didn’t want to cut the cinder block wall out when I put the door in. That would have put the threshold right at ground level, and I didn’t want to create a means for water to run into garage through that door opening. So, the doorway essentially has an 18” tall threshold, which would make it difficult to run the sewer hose over.
The sewer hose will only be running through the wall pipe when I’m actually dumping, which typically only happens when we return from a trip. I try to dump my black tank sometime close to the end of a trip, so we never arrive home with full tanks. But, there’s always something to dump. It’s purely a convenience for me. Without this new dumping option, I would have to move the camper up to the dump pipe in front of where the cars park. Not a big deal, but it is a little extra work and the concrete apron in front of that garage bay isn’t level.
