I looked in the tank and noticed the hose was not pointed down the overflow tube. I clipped the hose on the tube so it would be squirting down the tube and I think all is well. I am not sure why a 'press and hold' flush would have filled it before, but maybe it was just the additional volume of water never made it out so the bowl was full. Does this sound plausable?
More testing is needed to confirm. I am eating four cans of baked beans right now and going to Taco Bell for lunch. Wish me luck.
