I rebuilt my Aria toilet, not a big deal but expensive however the new control board seems to be better. When I took my toilet out and then put it back it I found that the water supply was difficult to reconnect due to the confined space, it kept leaking, tried several times and finally went to Lowes and got a short flexible wire braided supply line that is sold in the plumbing section. I put a loop in it to provide flexibility and it was easier to hook up and didn't/hasn't leaked in 2 years.
