So we just purchased 4 new Toto toilets, 3 Drakes and the Promenade II. The CST746 Drake toilets are giving us soooo many problems with leaving debris in the toilet after every single use by every family member. It’s the Drake 2-piece https://www.totousa.com/drake-two-piece-toilet-128-08-gpf-elongated-bowl-universal-height. We’ve only lived in the home two weeks and I’ve had my hand in the toilet more times than I care to admit trying to clean the inside after a child goes number 2. More than just that, in general the inside rim just looks dirty from splashing or whatever hits the inside rim. I’ve never experienced this with any other toilets we’ve had. My husband thought there wasn’t enough water in the tank but when I looked at videos online they look comparable. It seems water just sits pretty low in the bottom of the bowl? And the shape inside the bowl seems odd and causes my kids bowel movement to get stuck and then slide down the bowl as it flushes causing skid marks that remain. I’ve searched the forum and it seems years ago people used Clorox Teflon bathroom cleaner which is no longer made. Please someone tell me there’s something we can do to fix this!!! I’m so grossed out! I was so excited to get my new Totos and now my toilets all look absolutely disgusting.
