I am considering a tankless to preclude tank failure. I have had 3 failures over the years. One was semi catastrophic with an insurance claim over ten thousand dollars to clean up and replace AC ducting, flooring and wall sections. The others were fortunately less severe, but mold was a big problem (FYI UVC in the AC really helps). A neighbor had a full catastrophic failure and ended up having to stay in a motel for over a month because the entire house was flooded. I don't know why housing codes don't require the tanks to be closer to the house exterior with a large drain. I would be interested to hear if the tankless are less prone to failure.
