Why do you say that? All the YouTube guys I’ve seen say the opposite, to use it sparingly. They’ve not said why, just that you don’t need much.

Yeah that’s a good tip for silver solder and/or plumbing solder. It should flow to the heat source.

Awesome. Definitely not crazy high temps. Why’s that with concrete slabs? Is it in case of movement or something? Sorry for the radio silence, this is work at my MILs and I was there until midnight last night trying to get it done…

This was the answer I was hoping for, my propane torch didn’t seem to be hot enough to melt the silver solder I got first, and I don’t have easy access to oxy/acetylene and don’t want to buy a new torch. Not sure why all of the plumbers here don’t use solder, but mostly it’s o-ring fittings these days.

Thanks for the tips! Fingers crossed my joins are good…
