My error cost me a hot water tank (it froze). Totally my fault. So I replaced it. And in the process, swapped out the plastic fittings, flexible hoses, and bad clamps for PEX with push-to-connect fittings to allow flexibility and reliability. This isn't a full on how-to video. It's just a short video to show how it turned out. There's a zillion videos on how to replace hot water tanks already. But I couldn't find any that shows these particular fittings.
