American Standard toilet makes random "pressure release" sound.

Dear Terry and message board,

My wife and I have a slightly less than 2-year-old home with new American Standard toilets with the 3142 valves. The toilets work great, and as far as I can tell do NOT leak. However, at random times they'll make a sound as though "releasing pressure."

It's not a flushing sound, nor is it the same sound that happens when one forces the ball down to cause the valve to allow water into the tank. It's more of a very fast (and fairly loud "PFFFFFFFFFT" sound!)

Is this "normal" for the American Standard toilet? Is it a sign of problems to come? We know this is happening on at least two new toilets...
