aquia dual flush toilet

Hi....we just had a reno and had the dual flush toilet installed. (two of them)
One of the soft close toilet seats takes a number of tries to get it to stay up....not too great for the males in the house. We cannot figure out how to adjust this.....is there anyone out there that can guide me through it? Look forward to anyone's help.

If the tank isn't tightened down evenly, it could lean forward and make putting the seat up far enough to stay would be impossible. Does the tank wobble if you push on it?

I just picked up a toto aquia dual flush to be installed. Are you happy with yours, and was the installation a big task? we already have 2 ultramax toto and are very happy with them, but went with this aquia because it was a godd price, hope we did right !!

I've had two installed, and the Ultramax and the Drake for the last few years.

They all work well.
The Aquia takes a bit longer to install, but looks very nice when done.

There is more information on the Aquia here
