Why does the toilet flush on it's own? Without any warning , at any time of day (usually no more than three times a day) the toilet flushes by itself. Because there is no warning sign, I have not been able to see the phenomenon, but hear it when it happens. Late at night when it happens is particularly eerie.
Thanks!

Your toilet may have a slow leak. Put some food coloring in the tank and check it in a while and see if the color is in the bowl. If the bowl gets too full it will flush itself (or I had one that would.)

If a dog barks his head off in the forest and no human hears it, is he still a bad dog?

There are no bad dogs. Just bad owners.
