Love this toilet! All the features are amazing. My contractor was very impressed. It arrived on time in beautiful condition. If the power goes on there is a backup battery so the toilet still works. There are 3 buttons on the toilet and the rest functions automatically. This is better than getting a mounted toilet because the plumbing is hidden you don’t have to break into the wall to reach it. I believe DeerValley also offers free replacement parts. I hope this toilet last for a long time so far it’s been a month and no concerns.
