Answer: 
Well, Dual-Flush means you have two types of flushing. The Dual flush has a handle with two levers, one green the other silver. The green is used for liquids and the silver is used for solids. The silver handle is used in conjunction with the green. When the silver handle is used it pushes the green one as well and allows more water to be used. I believe the green uses 1.1gpf where the silver uses Read More

Answer: 
You can save water by using one flush option for "number 1" and the second flush option for "number 2".
The system knows how much water to use based upon which lever you use for flushing.

Answer: 
Dual flush saves water and money. The regular shaped lever is two parts. Green for liquids uses less water (the majority of your bathroom usage) and standard lever for solids. The solid lever provides more force and water.
While it seems silly, the amount of times you flush a toilet during a week can easily compound and save or cost you money.

The "flush rating" is not the problem so much as the water being too low in the bowl so that solid waste lands on the porcelain and takes 15 flushes to wash it clean. Tell me, how does THAT "save" water?
Although I'd like to buy new, taller, toilets now, I'm keeping what I have until toilet designers get a clue and design a toilet with a trap that leaves enough water in the bowl so that solid waste does NOT land on the porcelain!
My toilet ALWAYS works with only ONE flush - and that's with three large sealed containers of water sitting in the tank to reduce the amount of water used in each flush.
The key is that there is enough water surface IN THE BOWL to prevent solid waste landing on, and sticking to, the porcelain, which requires MANY flushes to get the bowl clean.
I'd rather deal with a toilet a little lower than I'd prefer, rather than deal with solid waste landing on and sticking to porcelain and having to flush 15 times to clean it off. Read Less

I wanted a taller toilet, but so far I have found none acceptable because solid waste lands directly on the porcelain, instead of in water, and requires as many as 15 flushes to get it clean. How does THAT "save" water????

My current (old but pretty) toilet has water covering the bowl so solid waste lands in the water, requiring only ONE flush to get it clean. And this is with several closed containers of water sitting in the tank so that less water is used for the flush.

The KEY is is not so much the amount of water in the flush as it is the porcelain bowl being filled/covered with water so solid waste doesn't land on the porcelain. The cause is the trap design that keeps the water level in the BOWL too low to cover the porcelain. There is no way to fix it so that more water stays in the bowl because over a certain water level, the trap just sends the water down the drain. When will the toilet makers get a clue?

I'm keeping the toilet I have - I'd rather deal with it being lower than I prefer, than deal with having to flush and flush and flush until the solid waste gets rinsed off the porcelain. How does THAT "save" water????

Answer: 
There is a white vertical tube on the right side of the tank. Make sure that the circular ring is tightly on top of it. If not, then the water that is supposed to go into the BOW:L will go into the TANK instead , and you wind up with low BOWL water level and your complaint. :-)

Hello, my name is Leah with KOHLER Customer Service. I am happy to assist you with your toilet question.
I apologize you were unable to find the information you were looking for. The Highline toilet, model 45979-0, will have a water height that measures 5.5 inches. This measurement is taken from the rim down to the top of the water surface, perhaps you can compare this to you existing toilet to see if it meets your preference. Additionally when the toilet is flushed, water will come from opening around the full 360 degrees of the rim to clean the sides of the bowl from use.

Rated 4.2 out of 5 by 95 reviewers.
Rated 5.0 out of 5.0 by Functions well and Looks great! Our contractor recommended this toilet. It offers comfort height and economical dual flush features. It works well we just had to get used to the "less water flush". Nice thing is the flush is very quiet. It took our contractor very little time to install the toilets...we replaced 3 older models. So far....quite happy! July 26, 2016
Rated 5.0 out of 5.0 by Great Product Have had this toilet for two weeks. Our old toilet was constantly getting plugged. This has never been an issue with this one. The 'light flush' is strong enough to handle a bit of toilet paper. After reading the reviews, we purchased a new seat and didn't bother unwrapping the one that came with the toilet. July 23, 2016
Rated 5.0 out of 5.0 by Does what it's supposed to Installed last week and it works great. Came with everything needed to install although I decided to add a braided stainless steel flex hose for the water line with built in shut off valve to make things easier. We like it so much, we're going to get 2 more this weekend. May 27, 2016
Rated 5.0 out of 5.0 by A royal flush! Everything worked as needed right out of the box. While I think the mounting bolts could have been made to the specific length necessary for this model, instead of using generic ones, they worked. The dual flush mode works really well, and though I think the extra cost was high, it does work. Only installation problem I faced was lining the bowl over the mounting bolts while trying not to damage the wax ring. Either the bowl could have been lighter or I need to be stronger. August 30, 2016
Rated 5.0 out of 5.0 by Good purchase Great look ,very good quality, very little noise when flush and save money strong water pressure Easy to used September 6, 2016
Rated 4.0 out of 5.0 by Time for us to upgrade! Old toilet was 28 yr old and it was time for a new one. Of all toilets on display we picked this one! We know the Koehler brand to be the best. I gave 4 stars because we are still getting used to the dual flush system and the higher seating! I feel good that we are using less tank water. No problem with installation by Home Depot contracted plumber. Just an easy transaction all round. August 30, 2016
Rated 5.0 out of 5.0 by Good and reliable toilet model We wanted a high quality toilet that saved water. The double flush system is easy to use and works every time. September 6, 2016
Rated 5.0 out of 5.0 by Really good toilet The toilet was easy to instal and works wonderfully. It is sturdy, looks nice, and uses much less water than the regular one we had. July 26, 2016
