Once you experience a powerful flush like this, there's no going back to ordinary toilets. It was very easy to install and so far I didn't have to make any adjustments to the pressure tank.

The toilet is fantastic. It’s so powerful it can flush a bale of hay down the drain. Unfortunatethe Kohler-made flush linkage that drives the actuator did not work correctly. I strongly recommend spending $30.00 to buy the Flushmate universal linkage for this unit.
