Christmas evening the plumbing backed up due to tree roots. Ruined the new laminate that was 6 days old. I pull the toilet and set it on the back porch while I was ripping out the wet laminate. It sat there for a few days until I decided it would be a good idea to take it out into the yard and dump out the water. So I did. Water dumps out, all is well. When I started installing the new laminate again, I brought the toilet back inside. I figured it would be better if it was warm when I put it back down. By the time I finished with the new flooring, it was late so I left the toilet, still upside down, on cardboard. Woke up the next morning to find water everywhere. I guess in my stupidity, I neglected to consider any frozen liquid still inside the thing. But, in my (weak) defense, when I turned it over in the yard a bunch of water came out so I figured it was empty. So, third time's the charm I hope.
