This is one of my favorite purchases of all time. I can’t believe how well my toilet is working. I am so happy. Sometimes I wake up in the middle of the night just to go flush my toilet. It is as absolutely amazing. Just the sound of the tank filling up is music to my ears. Thoroughly happy.
Easy install, very quiet
