It started with a leak in the basement. Looks like it's time to take the downstairs toilet apart, get a new wax ring, and re-seat it. Because something unpleasant is happening during flushing. Eww.

Unfortunately, after turning the water cutoff valve off and on a few times, the valve failed. This means I can't turn off the water to the toilet, which is a major problem begging to happen. I consider a raging flood on the first floor of our house a major problem.
