  1. Do the upper joint first. As you said.. The solder flows toward the heat.. Think about it. 🤔 and you don't clean up drips with flux. You use a dry rag.

  2. From working in the commercial/ industrial side of plumbing but originally coming from residential. They’ve taught me to just use a scotchbrite pad and clean it with a clean rag. The acid from the flux brush leaves the chemicals on the pipe and discolors the pipe. The way they’ve taught me looks really clean. I also heat the fitting and clean the excess flux that comes out of the fitting to avoid the goobers and Saulder running down the pipe. Lot of ways to do it 🤷🏻‍♂️

  3. I know this may be a dumb question, (or wait depending on who you are, there's no such thing as a dumb question) but, is soder for Cooper pipes the same as soder for copper wires? (I'm sure it is but just wondering)

  4. What do you clean the flux off with after using it to clean your joint ? Pro tip use a dry clean rag and be fast . It will wipe off the excess solder and make it smooth and shinny . After that wipe it off with a clean wet rag , that will help clean and neutralize the flux so it won’t corroded. I updated my comment as I may have been a little buzzed when I typed it out haha .

  5. Yeah, yeah, yeah. Let's get to real life. Show how to solder a ball valve (horizontal) about 8 inches off the ground. Now show a propane bottle with nozzle you buy at Home Depot or Lowes for roughly $25. The valve is about 8" from the wall or closer. Let's see it.

  6. I've done this for years, usually in the worst possible places. The worst possible time with zero room for error. The best investment I ever made was a propress tool.
