In preparation for the new drain pipe, the heat duct that supplies the upstairs Bathroom had to be rerouted a bit. The old cast iron drain pipe is at the far left. The new PVC drain pipe is set in place (between the black cast iron pipe and the heat duct).
While I was down here working on the duct work, I fixed a few leaky ducts with duct tape.
The twisting mess of the pipes, ducts, and wires. I hope to get all of this a little more organized some day.
The drain stack where it comes down from the upstairs Bathroom and makes a 90 degree turn toward the sewer.
The drain pipe running under one of the heat intakes. Notice, also, how the drain pipe runs so near the old cellar door that it wouldn’t be able to open if it were hinged. We plan to run the new pipe a little further away to enable the use of the door.
