Toilet lasted 22 months, replaced it

I had a leak problem when it water would not shut off after a flush. It dribbled all night and I got up to a wet floor. I bought parts and pulled it to put parts in. There is a spring on the flush pedal, it comes off your done.

I bought a Dometic 310 to replace the now defunct Aqua Magic. Whole new game, flushes around the entire rim not just a spray from a nozzle at the back, and it has a slow close lid. I'll never go back to the Aqua magic.
