screaming toilet

[Campercat]

When my daughter turned on the shower this morning, the toilet started screaming. We took the tank lid off and the gmax popped up above the top of the tank. She had to turn off the water supply to the toilet to stop the shrill sound. I pushed the gmax back down, but when I turn on the water supply to the toilet, the gmax pops up above the top of the toilet tank again, and water keeps running through the tank. I've fixed the tank innards in old 3 gpf toilets, but this gmax thing in my Toto is a new challenge. And what caused the screaming

That's interesting. I have no idea, but I'm sure Terry or one of the other pros will have an answer. Sunday is often a bit slow on the forum, so hang tough. My guess is Terry is skiing today.

Push it down and turn it. There should also be a small white piece of plastic which locks it to keep it from rotating and popping up.

Thank you for responding. There was a small piece of white plastic in the bottom of the tank. Using the diagram for the Korky flush system, I figured out where to install the lock, but to no avail, the mechanism still pops up when the water fills the tank. I took the G-max apart and rinsed it out (it wasn't dirty) just to see if that might help. It didn't. Nothing appears to be broken.

Like hj mentions, it's a slight turn until it catches, and then the white tab locks that position.
When it catches, it won't rise up anymore.
