I'm installing a bathroom in my basement, I'm done with the PVC Drainage plumbing under the concrete and bathroom framing. I'm about to start installing the copper water lines (shower/vanity/toilet). Question; I'm going to sweat/solder the threaded end into the shower valve.. has anyone else ever done this? or recommend this? I've been told it's common and has a less chance of leaking then tape and pipe dope.
