Exorcising a possessed toilet

I'm not a big believer in the supernatural, but an upstairs toilet has shaken my belief that paranormal activities are a myth. So for the fourth time in as many years, this toilet needed to have the fill valve replaced as it would not stop running. I've decided if a new valve doesn't work, I'm calling a priest to have the toilet exorcised.

In this toilet I've already had fill valves from Fluidmaster, American Standard, Korky, and today I installed a Peerless/FillPro water saver anti-siphon fill valve. It's much smaller than traditional ones and is only about two inches high inside the tank. I'm hoping this will finally solve the problems and am keeping my fingers crossed.
