Genuine Part Gp1059291 Canister Seal

Easy to install.

The toilet kept running and I looked on YouTube for the answer. It was this simple little ring. I tried cleaning the old one first. But there seemed nothing wrong with it; nothing to clean off of it. So purchased this and replaced the old one. It works like a charm! And it was much cheaper than having a plumber come out and do it!

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!

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.

The hardest part of this was figuring out which one to order. Once I figured that out & this arrived it took me less than 10 minutes to remove the worn out seal, replace it with this & have the water to the toilet back on & flushing. Wooohooo. I was cursing Kohler when trying to identify which seal needed to buy - now that I know that & how well designed the system is for easy seal replacements I am back in love with Kohler products.

The installation of this replacement seal was easy, but unhooking the valve cylinder in order to install it was the real pain. It stays in place, and the toilet no longer runs, so yeah, it does what it says on the blister pack.

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!

I have a Kohler Wellworth toilet with tank 4436 (tank numbers are stamped on the inside of the tank). I pulled up the parts list on the Kohler site and saw that this was the gasket required. My old gasket was red and severely degraded (although I didnt see how bad until I pulled it off and replaced with this yellow one). Toilet tank would slowly empty until the refill was triggered at random times during the day. Replacement was very easy, and I didnt remove the chain, you can access everything without doing that. Very easy repair and saved me a plumbers visit, my friend paid $139 for the same job. I appreciate all the comments left here in the reviews that explained so clearly how to do this.

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.

Its worth the price, dont waste your time on the cheaper knockoffs. Just get the goods and sleep well at night. No more leaking or running water. A quick you tube check and you can do it yourself. Sixty plus yo woman here, not a quick learner, but a good learner. Look everything up, your system, how-to etc. Do it once, do it right. The cheaper ones buckle, dont waste your time and money.
