Kohler Highline Flush Test

Video Transcript

The new version of the Kohler Highline toilet it was released in 2016 it is chair height and elongated 1.28 Dow and flush here the bottom level is not the greatest on this toilet so that could definitely affect the bowl rinsing power I will take a look at how it flushes so it looks like it has a pretty powerful flush we’re going to see how it does putting some cinnamon in the bowl it’s the tank of the toilet and I’m going to show you how it looks flushing it really quickly and this is what it looks like when you hold the lever down for a while we’re just going to spread a little bit of cinnamon on the toilet and see how the bowl rinse does okay this will just be a regular quick flush as you can see it actually did a really great job of clearing the bowl morale the story is if you want a clean toilet don’t pour cinnamon in it we’re just going to see if there’s any difference in the flushing capabilities when you hold the lever down so let’s take a look so I held the lever down until the tank was empty and pretty much the bowl is clear that’s actually pretty impressive um it actually performs better than another 2016 model of American Standard that I have um so two flushes and I would say anything in this bowl will be completely cleared quickly I’m just going to show you the American standard 1.28 gallon flesh it’s also a new model toilet and I’m just showing you the difference in the cinnamon test bowl rinse okay here we go so as you can see there is a lot more left in the American Standard Bowl as compared to the cooler and the color just has a superior bowl rights even though I actually have had zero problems whatsoever with the American Standard it’s the h2 option I’m actually pleased with both of these toilets very quickly I wanted to point out the fact that I could not use the Kohler provided flange bolts and that was simply because my flange was less than perfect and the alternative bolts just would not work with my application so this net would actually go down inside of the flange and then from above you would through the toilet actually put this nut down into this bolt and then screw it in from above so that down here then that would actually be flush with this and you wouldn’t have a bolt sticking up at all unfortunately this simply would not work for me because the nut was too short like I said I had flange problems and I unfortunately wasn’t able to use it so overall I would definitely recommend the Kohler Highline 2016 model it does an excellent job at flushing solid wastes and you have the option of holding the lever down if you want to have more flushing power but it will also save you a lot of water thanks for watching and happy flushing
