So a little more progress - starting to run the in floor heat pipe:
Day 1 - first loop run
Day 2 - second loop run
It's been incredibly slow, painful, and tedious. It should have been a one day project, but when they blew insulation above, they didn't tarp, and now the entire floor, including the grooves for the tubing, are blanketed with a thin layer of foam. Tried solvents, dremel buffers, and sandpaper, and so far only sandpaper really works. So it's hands and knees drudgery getting this job done. Displeased.
