Man, that's the worst feeling, watching your map just dissolve. I once had my only water filter crack on the first day of a three day loop. Had to boil every single sip for two days, which meant way less water and so much time just sitting by the fire. That sun-drying trick is smart though, I did something similar when my notebook got soaked. You just make it work with what you've got left.

Totally get that. Spent like a month on a magic system's fuel source. Could not decide if it should be crystals, a liquid, or like, emotional energy. Drove me nuts. Ended up mixing two ideas after I saw how batteries work. Sometimes you just stare at it too long.

Oh man, that's a classic move right there. Learned the hard way in my own place that you gotta trace every single line back from the fixture. Found a random valve tucked behind the drywall in the next room over, no joke. Always shut off the main house supply for any real plumbing work now, saves the surprise shower.

Your buddy's heart is in the right place, but a separate conduit for every single residential drop is overkill. The cost and labor just don't make sense for most houses. A better middle ground is to run a single, oversized smurf tube from the demarc to a central panel. That gives you a clear path for future pulls without the expense of multiple dedicated runs.

What if it's a secret hit list?
