very interesting

That is one up on me??? was that supply or return

I think the return, Charlie, but I didn’t try to figure it out. It was a complimentary inspection for my preacher. My eyes got real big, my mouth uttered an expletive, I took a photo, and I moved on.

How about drainage pipe??

Needs insulation! Asbestos is recommended.
