Genuine Part Gp1059291 Canister Seal

This was a necessary repair part to fix a toilet that kept randomly running. It was easy enough to pull the canister out of the tank and replace the seal. The old seal all but fell off on its own. There are some good videos on YT that show exactly how to replace it.

This product fixed my Kohler canister type toilet from leaking. The old seal was probably old when we moved into the coop in 2012. It started leaking only in the summers, then this year 2018, it was leaking all the time. I had gotten plumbers to come and look at both toilets that were leaking. They said they had to order parts, charged me $179 for nothing and they wouldnt come back. So I viewed the video on YouTube several times and got up the COURAGE to fix it myself (Im 72). It took about 2 hours start to finish partly because I had to remove and reinstall a wooden over toilet cabinet. So after an hour it was done and works 100% better than before. Oh, I fixed the other American Standard toilet flapper as well.

I surfed the web to find out why my Kohler class five toilet would periodically run. The consensus was that this little yellow gasket was worn and needed to be replaced. There was a great Kohler video that explains the steps to make this little fix. I replaced the gasket using the steps and the toilet was STILL running periodically so I flushed it once and checked it a half hour later and realized it was still losing water in the tank. I turned off the water and flushed the tank to empty it. Then looked closely at the side that did not have the gasket and realized there were TINY pieces of plastic from the old gasket that needed to be cleaned off. Once that was done, I turned the water back on and checked it a half hour later and the water level had not decreased. So, that step is not mentioned in the video but it is important when you are replacing this yellow seal.

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!

This seal works well, easy installation,took me less than 20 minutes to replace. Saved a bundle repairing myself (no that handy) thought I would need a plumber.

Exactly what I needed and cheaper than at the hardware store

This worked like a charm. I only gave it 4 stars . Because it had a perfume odor on arrival. I am chemically sensitive and the thought of my toliet smelling like that had me worried. I am happy to say that after sitting outside for a week open and then washing it several times it had no odor, and still retained its shape, thickness, and ability to seal. Very strange to have something so utilitarian smell like air freshner or perfume. Not what I expected and hope this is not a trend.

Genuine part so it was a perfect fit for a Kohler commode

We have a Kohler Cimarron toilet that has the Red valve seal. This was a perfect fit replacement. Reason we got it was because after 2 years the toilet became very difficult to flush; you really had to put a lot of pressure on the flush handle - it was like it was stuck. Replacing this made all the difference - its back to new. A little tip here, the package comes with instructions on the back so when you come to the part where it shows to rotate the center disc portion of the canister mechanism counter clockwise to loosen, well when I did that it sounded like the plastic was going to snap at the shaft. So heres what you do, just lift the actual canister up enough to reach down below it and grab the center shaft at the base where it connects to the toilet tank. It will feel like a + sign in your hand - take that and turn it counter clockwise to loosen it, and then do the same (clockwise) to tighten it. Its a much sturdier way to take the canister mechanism off and on without feeling like youre going to snap the center shaft off.

Had a Kohler toilet that had a leak due to bad o ring. I looked up the part and this was it. I installed it in about 1 min. Problem solved. Very satisfied.
