I have an American Standard one-piece elongated Lexington (331 2006) that has water leaking into the bowl and causing quick phantom flushing. The leak is coming from a couple of the rim flush holes closest to the tank. I've replaced the the entire tilt-valve assembly (everything including the bottom seal, tabs and screws, actuator disc and tilt valve). I've also replaced the fill valve (with a FluidMaster 400a), but still the trickle into the bowl. The flushes are about 10 minutes apart and really quick, about 5 seconds long or so). I don't know if it's significant, but there are tiny air bubbles, like champagne bubbles near the bottom of the fill valve. We did a color test - nothing. We've played with the height of the float - nothing. Any suggestions on how to fix this? via /r/DIY http://ift.tt/2wikdFw
