Easy to put in after I read the reviews. Fixed my running toilet.

As others have said, this comes with no instructions, just parts. Installation is not hard, though. I removed the old parts (work to rotate 1/6 turn clockwise then pull), disconnected the new flapper, inserted the vent into the gasket, inserted the points on the bottom to match the triangular hole, then worked it all 1/6 turn counter-revolutionary (pushing down with my left and rotating with my right). All set.

I didn''t have to, but I see where the advice about vegetable oil or cooling for the gasket would make it easier.

In Atlanta, two different plumbers wanted $395 to install kit, and both said that replacing entire toilet would be easier. Instead, I bought the kit. After reading the reviews, I dreaded the installation but I could not bring myself to pay a plumber. I took one reviewer''s suggestion and applied a little dish detergent on bottom of rubber gasket. I lined up the vertical valve and saw that you could only turn the valve counter clockwise 1/3 twist to make the water line marking face the front of toilet. So I lined up the valve so that the water level marking was perpendicular to the rear of toilet. I press down hard and turned counter clockwise and it went perfectly. The entire job took 5 minutes.

This part works well, but it’s a ripoff because the design of the original broken piece that I had to replace is faulty. The top of the toilet tank hits the plastic piece at the very top of the valve (where the fill hose connects into it with a clip) and so that black plastic piece breaks off the top of the canister assembly. You cannot purchase only the broken piece of plastic. You have to purchase the entire canister assembly—lots of parts that you have to pay for, but don’t need. I thought it would be better to go ahead and replace the entire canister assembly anyway since I now have all the new parts—but when read the instructions for installing the canister assembly, I was really bummed, because you have to remove the entire toilet tank. They must be kidding. Instead, I decided to replace only the part actually broken. I simply twisted off the center column (with the broken piece) by turning it a 1/4 turn counterclockwise, removed it and used (only) that part of the entire new assembly. This was quick and easy (thankfully), but Koehler should sell that one part that breaks, so that you don’t have to purchase the entire canister valve assembly. Also, the new canister assembly that I received is not exactly as shown in the picture—it’s a better design. It does not have that fragile plastic “cup shaped” piece at the top—the plastic piece that the flexible hose clips into and breaks when the tank top hits it. Instead, the top of the replacement assembly that I received has a very small and simple nozzle, over which I shoved the plastic hose. Because the new one is not made with that fragile cup-shaped plastic top, it sits lower down inside the toilet tank and the toilet tank lid no longer hits it. I am really glad that Koehler improved the design this way, but still they should sell a replacement for only the old fragile part that breaks so that we don’t have to pay for the entire assembly.

Glad to have my toilet flushing again.

Took me 10 minutes to install after reading the suggestions in the reviews.
Use the olive oil between the donut and the plastic assembly. The idea is to make it easier to turn the unit into place. The donut doesn''t move, but the unit does.
It only goes in one way (no effort) so the 3 plastic tabs are grabbing the ceramic part of the toilet. Then you push down hard (use a dish towel to cushion your hand) and turn counter clockwise.
It''s easier if the flapper is off and the flushing assembly is out of the way.
Practice putting in the old part so you know what to expect.
Take out the old part by pushing down on the unit and turning clockwise.
If you''re taking out the flusher, the plastic ring turns clockwise to loosen.
BTW, this part is for a Kohler Santa Rosa K-3323.
And I''m NOT a handyman by any stretch of the imagination. After 41 years in finance, I finally have time (and Amazon reviews) to help me through DIY projects.

Arrived in only one day! Replaced the broken part in 2 minutes--a snap! The bottom of the inner column had broken off and must have been flushed away. Removed only the main part of the flush valve (not the seal, etc.) so some of the new parts are not used. The new valve simply inserts into the little slot at the bottom of the tank--give it a slight turn to lock it in place. Reattach the chain and we''re back in business. Works perfectly. Very easy. Very happy!

This gasket is by far, the most challenging Flush Value and Gasket I have ever inserted. This was my first time installing a replacement valve in a one-piece toilet.

The key to installation: Leverage. Find a way to be able to gain leverage and the ability to turn the flush valve, all the while pushing down as hard as you can AND twisting against the gasket in order to lock this into place.

My trick....
One foot on the rim of the toilet, get the gasket wet before placing onto the valve. When pushing down on the valve, you must be high up in order to press the thick gasket down enough to start the flanges on the valve to lock into place. Get a dish towel and wrap it around the valve. Push down will all of your might, squishing the gasket, using the dishtowel to slowly turn the valve into the locked position. Takes a lot of strength and effort...but honestly, probably the most ingenious design for a flush valve and gasket that survived 8+ years of bleach tablets in the tank...where as the standard gaskets wear out yearly...yet are easier to replace.

This worked great; perfect fit and easy install. I did have to drain the water from the tank, and take off the tank, but no big deal. I used a shop vac to get the water out, and then used a strap wrench to get the big nut off. It''s 4 inches or something like that ... I didn''t measure it, but I''ve got lots of tools and didn''t have a wrench that big! But, it was pretty easy with just a strap wrench and after that it was just putting it back together. It came with new gaskets to go between the tank and the bowl, and of course between the tank and the canister valve. Highly recommended. I replaced the fill valve at the same time just because I figured it was easier to do while I had it apart.

I read a couple of the reviews saying to be careful with making sure it was the right part. I called Kohler customer service, and they were fantastic. I actually couldn''t decipher from the tank markings and so forth what the model # was, and they helped me figure it out. Then they recommended the right part # (it was listed inside the lid as part # 1080691, but the correct # is this one --- 1080961). I hope this helps everyone. My wife is happy again because the guest bathroom toilet doesn''t keep running all the time.

I went through 3 flush valves... yes 3... after 3 days the hold down clasps broke cause a slow leak yes 3 times of doing again and again and yes again. After contacting Koher rep locally I was informed the Kohler product will have the flow line identified on the down spot. The product I bought here on Amazon did not have this indication ….FLAG....FLAG. After purchasing my product from Kohler store I found a big difference especially in the gasket, which would explain you all having problems installing this product. The gasket for this product is not the same as the original. People go to the Kohler reps and get the right product and get the proper replacement parts...……...pay the price to get the OEM replacement part...…...end of story.

Genuine part and matching the replacement part number listed under my toilet lid. The instructions that came with the part were very vague and not helpful. It just basically says ''take out old'' and ''install new''. What they should have said were, - Turn off water supply to the tank. - Empty the water out of the tank. - To remove: Rotate the current valve counter clockwise a 1/3 of a turn. Lift up & out. - To install: Place the replacement valve with the grooves matching the cutout (1/3 of a turn counter-clockwise). Press down hard on the gasket to compress it and rotate 1/3 turn clockwise to lock into position. Tip: If this is difficult to turn, place a few drops of oil (I used olive oil) on the top and bottom of the gasket before re-attempting. Hope this helps someone!
