flapper question

[sunliner]

We went out today for about 45 minutes and came home to find one of the toilets running. found the flapper full up position. I closed it and all was fine. Hopefully septic system didn't get too much water.
Wife said she used the toilet just before we left but swears that she heard the toilet cut off before we walked out the door.
I have never heard of a condition that would pop the flapper up without someone using the lever...is that possible?
Septic tank was pumped out about 3 months ago and the guy said everything looked good on that end.

I don't know your wife so I can't call her a liar.
I wouldn't do that even if she was.
Possibly mistaken maybe.

You say it was full open. The only way I can see that happening is the handle got stuck in the upper part of it's action and held the flapper open.


OR. . . . . . . .

LoL! that's pretty much what I thought. I;ll give her a break, the last week or so has been busy as hell. Thinking she just got in a hurry and didn't notice it was still running. thanks
