It's in the mechanical/electrical room.
And the furnace has arrived. Some day we plan on getting one of those outdoor wood burner type furnaces. Apparently we have to put something on the furnace now to make it easier when we install the woodburner later. For now we will have natural gas.
I have no idea what this is, but it came in with the furnace so I assume it's part of it.
NOW....with walls up....
and holes in the floor,
I can think about it! Guess what though? It's too late! I would not have had my washer and dryer where he put it, but oh well, isn't it really minor in the big picture of life? See how that pipe is coming up in the wall in the above pic? And this pipe is next to the wall in the below pic? All of that had to be decided and installed, before cement was poured for the basement floor and walls..
