Genuine Part Gp1059291 Canister Seal

My Kohler Cimmeron developed Phantom Flushing after a few years. Replacing this part fixed the problem. There were instruction on how to install on the back of the package, however I needed to watch a handy YouTube to complete the job. It was very easy and Im not at all handy.

I have a low-flow Kohler toilet that had a phantom flush. That is where your valve seal has gotten old and the water leaks out slowly. All of a sudden you hear the toilet start to fill again all by itself in a pattern. That is called the phantom flush. A very slow leak into the bowl that finally results in the water level getting so low in the tank that it flushes itself. Did some research and found out it was time to change the valve seal. Seems like they only last a couple of years (less if you use chemicals in the tank itself for cleaning). Bought this inexpensive little piece. Looked on YouTube for a video on replacing a canister flush valve seal. And voila! Toilet fixed and no repairman bill. Bought 2 of these at the same time so Id have a spare a couple of years down the road when this one fails. $7 is much better than a $75 plumber call! Do it yourself - you can do it if I did!

Had a Kohler toilet that was getting increasingly hard to flush. It was obvious the flapper was sticking somehow, but when I opened the tank I was baffled by the weird design. I went to YouTube and found a video that showed how to twist the center stalk of the “flapper” and remove the long tube. Sure enough the old red seal valve/ring was falling apart and gummy like an old rubber band. Had to run a pocket knife around both sides to remove the crusty bits and then the new yellow gasket just gets stretched on. 2 minutes on YouTube, 5 mins removing the old gasket, and 30 seconds to install the new one.

The toilet valve was going on for about 30 seconds every half hour all day and night. I’d get up an hear the toilet running, then it would stop. Read about replacing this seal, a 10 minute job, and now the toilet works like it should. I noticed that the old seal had developed a small bubble which allowed a tiny amount of water to leak, eventually triggering the valve to fill the tank. This seal fixed the problem...no plumber needed!

After disconnecting the water line in tank, I had a little trouble twisting the yellow cap off -- was afraid it would break b4 it turned. But the gasket fit in the groove perfectly. But the tank still leaks -- green food coloring doesnt lie. DK if its another tank part or the valve at the wall. So, will call in a plumber after all. At least I know what the problem isnt.

Very easy to install, no leaks!

Easy to install

Exactly what I needed and cheaper than at the hardware store

product did what promised

I noticed that my Kohler (K-4436-AA) toilet would start running randomly throughout the day when it wasnt in use. Reading online it seems that a common problem for running toilets is that the canister seal becomes brittle over time and need to be replaced. There are some great videos on YouTube showing the replacement process for the canister flush valve seal. FYI, The replacement seal is a yellow color while the original seal is red, the product packaging shows that new seal is meant to replace the original red seal. During the seal installation, I confirmed that the yellow seal is indeed a perfect replacement for the original red seal. Additionally, since installing the replacement seal I havent noticed the toilet running randomly anymore. Im hoping that this permanently fixes my running toilet if I notice its running again there is most likely another issue causing the water running.
