John, you intrigue me with your post. I should pay more attention to the age of all plumbing components,  and need to think long and hard about  pvc,  pex, even steel.  What is considered best practice for plumbing , for health and for safety?Do folks replace all plumbing after X amount of time? Perhaps replace all bits every 12 years, or wait until they leak?   An opinion,or two  please.

Poplars in Joyce Kilmer

Good to hear that poplar can help you, as a hardwood , as part of a huge hugel, and more.   Still some pockets of old growth poplar in the South, most notably the giants in Joyce Kilmer forest.  A true cathedral in nature

I once was a blazing fast, accurate typist but certainly not now......yes, i made a weird typo. All the keyboards in our house are English/Thai, and I somehow miscued the switch there.   Sounds like you're an aficionado of language, good to hear.
Although my side of the family is more than 90% Scot, my wife has a more complex web on her side. Her maternal grandfather walked all night, hiding during daylight, as he escaped a civil war in China.  From Yunnan through Laos to Thailand, where local government affirmed he could marry ...provided he took the bride's maiden name.   Family still .iving in the house he built solo, all tropical hardwoods.  
Our teen did attend a Thai-English-Chinese school at age 3 and 4.  He is fluent, but I struggle.  My high school days had some Greek,  years of Latin.  University level Russian, some Czech, then Spanish and Portuguese.
That Cyrillic alphabet is simple compared to Thai complexity based on Sanscrit!

Rez, don't give up, before you toss the culprit out, try a remedy. If your stove is 6 inch and the glue is 8, for example, run single wall 6 inch pipe halfway up, or a bit longer.  Then I devised insulation with superwool, blocking off the airspace at top and bottom.  Worked on one project, hope it helps you

Rez, before you toss the culprit out, try a remedy that's worthy.

Glenn, that idea of a pipe routed to a air ram, hmm
A pipe dream at best, as you stated

That classic view across your lake, well, one can easily see why y'all settled there.  Magnificent.  
Trying to remember that  ruleม: Do not covet thy neighbor's fishing spot

Do you ever have much use for poplar? Besides this application,  i meant.  A poor firewood down South, folks call it a soft hardwood.    Yet I used poplar for exterior siding , not bad, the battens were easy to rip and to install.
When hand planed for the house interior i li,ed it,  some had lovely swirls in the grain. Green, black, and a bit of purple.  

Not exactly on topic for fish ranching, but I have to pass this along please
Mighty and wild, the deep diving sperm whale is deeply studied, yet remains a mystery wrapped inside an enigma wrapped in blubber.  
Our ancestors and theirs were once close, so to speak, about 90 million years back.  

This Guardian article reinforces our perception of animals talking among families, friends (combine this knowledge of orcas attacking yachts, and I can see something from The Monkey Wrench Gang afoot)

They call me Ishmael.........

With your climate, please strongly consider a bypass

Let me know  please when your family finds a spot.  While you decide, y'all can certainly gain experience with cob.  If I had to start afresh in these NGa hills , I would start with ceramic artists in or around Athens  , Atlant, Milledgeville ( home of the Southern Gothic icon Flannery O'Connor)

Many of them have diy advice, beginning workshops, or just old fashioned advice.  Art, science,  chemistry and physics combined.....what an amazing group of folks, honestly

Some in Athens area have largish bags of pure clay.  If you  then add  another stop by ________ building supply for sand and straw, ready to jump in.  After you perhaps  work on a small project or two, I predict you will source free clay , maybe work on sifted earth and locally cut straw for your cob.  
I trust y'all will have fun along the way.
