The mystery of the nice amount of hot and zero cold in the shower is revealed!
So if you look closely at these (double click) , the hotwater was replaced with copper at some point in its life. The cold never was changed out, but they put a copper fixture on the end of the galvanized. I'm no chemist, but over time, 2 dissimilar metals will corrode and like years and years later, bad stuff happens. The newer copper goes upward, through the attic to the north side of the house, down through and interior closet (exposed) and down through the "sink room/stairwell" downstairs to the basement. The replacement pipes for this will be 3/4", not 1/2" and will stay along the south wall where the bathroom windows are. Some walls on the 1st floor will have to be ripped out and repaired to insert plumbing.
