Recentl had to learn to solder pipe. Jacked up a delta faucet trying to replace the seats. Was original, dome had cemented itself into place and I turned too hard on this one, the third out of four that needed fixing. Turned the water to the house back on and it was leaking into the wall behind the shower. Plumber came out and said he could fix it without detroying tile and was going to get parts. He never made it back. Went to Lowe’s, bought some ball valves and by the grace of God soldered them into the lines going up to the shower. Now I’m minus one shower until I get it fixed, but at least we have running water and I learned a new skill.
This video was infinitely useful for getting the technique right.
