Genuine Part Gp1059291 Canister 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 was a genuine Kohler replacement part that I received (packaged in Kohler packaging). I am not a handy person AT ALL and even I was able to get this new seal installed on my Kohler toilet to prevent it from running. Kohler has some how to videos and manuals online. the estimated time to switch said 5 minutes, so i anticipated it taking 20 (thats how bad I am), but instead, I did it in less than 5. Glad I tried this myself and didnt call a plumber, I would have felt foolish.

Hard to rate just yet, as I need to see how well/long it holds up when continually immersed in a chlorine based tank sanitizing tablet. Kohler says not to use tank chemicals as they void the warranty, but the tablets have been a necessary evil for me to eliminate biological build up of rings in the bowl. The OEM seals were orange-red and had deteriorated within about 3 years. They got sticky and made using the flush handle very stiff as the seal was bonding with the plastic cylinder [part of the float system]. Not sure if they began to fail because of the chlorine or some material defect. However, it appears that Kohler has this new replacement seal which may be a different material and may withstand the chemicals better. In any case, the seal was a perfect fit and simple to install although the instructions were not useful. There is a trick to removing and re-installing the 6 solid plastic center shaft so that it is easily removed/re-installed. The trick being to rotate the shaft to unlock/relock it in its base, which is hidden from easy view. You may want to check out u-tube videos on the process if you are not familiar with this Kohler design.

I put off changing the gasket for awhile and I wish I hadn’t. It couldn’t have been easier. I watched a short video on how to remove the canister and it came right out. The whole process took less than 5 minutes

If you have a leaky/running off and on Kohler toilet, this part replaces the red ring that is on the bottom of the black tube in the toilet tank. The original red ring came apart easily over the years, and this replaces it. Check out the toilet lid underside for parts options, and if you cant determine it, call Kohler and ask what they recommend, with the part number required. To install this part: switch off water below tank, flush the toilet to drain the water in the tank, open the lid, remove black tube (squeeze widthwise), and scrape off red ring that has eroded. then replace it with this ring. replace lid, and turn on water, and flush! 5 minutes to replace, countless gallons of water saved

We have relatively new Kohler toilets, and none of them work very well. The biggest problem of all, however, has been these O-rings wearing out. Each toilet has one, and so we keep a few of these replacements on hand. Watch a YouTube video or two to see how to remove the old, worn-out O-ring and install this new one. Be patient, and be careful to not force any of the parts when taking them apart, because they all are made of cheap plastic. Remember the old days when Kohler built everything with iron and steel parts?

The old seal was busted and the tank would refill every minute. I was worried as I was not the one to install the flapper and I had never run into a cylindrical one before. Once I got it It was quite intuitive on how to install it and took less than 10 minutes for the whole thing to be taken apart and put back together. Now my toilet only flushes after use.

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.

The ring gasket it replaced was allowing a significant leak in my toilet tank despite no apparent damage. This causing my water softener to go through regeneration cycles approximately 3 times as often. I installed the new ring gasket and no more water leakage. Saving $20/month in softener salt.

Fit like a charm
