Hello; At some point a large enough quantity of water to be a problem will wind up on the floor. It can happen in various ways but it is more a matter of when than if. Most of my water problems have been a case of slow type leaks that happen for a long enough time to be significant. A few spills. I have only had two tanks dump a lot of water in a short period of time. I did not plan on having leaks or spills, but it has happened several times over the decades. I hope to be leak free but take precautions. I am glad that I removed the carpet from the tank area in the new house, that effort has already paid dividends. A filter leak put enough water out to be significant and all I had to do was find the leak and mop up the water. No damage to the floor of carpet, just some stand swelling. Good luck.
