Okay but "almost replaced a whole water heater" is a pretty big deal. That's a major job. How did you not catch that first? I mean, you have to drain the thing and disconnect all the lines. At some point pulling the old one out, didn't you stop and double check the actual leak? Seems like a huge step to skip over the easiest fix.

True, but @caleb_coleman88, people are gonna worry when new stuff shows up and they feel weird. The science might be settled, but that doesn't make their headaches hurt less. It just seems like a messy situation all around.

Honestly, I saw a video that made it seem legit, @davidmurphy.
