I think my city sewer pipe is about 20 feet under the street..
But, I'm wondering if there is warm air inside that long downhill run
of PVC going to the street??
I have a 90 degree turn inside a man-hole beside the house in the back yard.
I could dig up the cover and scan it for heat!
It might not be too hard to drop a folded back line down into that PVC..
Haha! digging down to a BTU mine..
I can just picture a couple of 80 foot PEX lines with an exchanger payload
on the end, slowly descending downwards towards that warm city sewerage..
